Muscle weakness is a common complaint, but the word "weakness" itself has a fairly wide range of meanings, including fatigue, decreased stamina, or complete inability to function. The range of possible causes of muscle weakness is even wider.
What is muscle weakness?
The term "muscle weakness" can be used to describe several different things.
Primary or true muscle weakness
It manifests itself in the inability to do with the muscles what a person wanted. Even if such actions are not performed for the first time, but a trained person is trying to perform them. There is a decrease in the strength that the muscles need, but there is none. The muscle is not working properly and has become abnormal.
This type of muscle weakness can result from a stroke, and it can also occur with muscular dystrophy. In both cases, weakened muscles cannot perform the usual load, and changes occur in muscle strength.
Muscle fatigue
It is sometimes called asthenia. This is the feeling of tiredness or exhaustion that you experience. The muscles don't actually become weaker; they still function, but you'll need more effort to perform the actions. This type of weakness is observed in those who suffer from chronic fatigue syndrome, sleep disorders, depression, chronic heart, lung and kidney diseases. Muscle fatigue may be due to the fact that the muscles do not receive enough energy.
Muscle fatigue
Muscle fatigue is when a muscle begins to function normally, but very quickly loses this ability, and recovery takes much longer than usual. “Fatigue” of muscles is often combined with muscle fatigue, especially if a person suffers from myasthenia gravis or myotonic dystrophy.
Common Causes of Muscle Weakness
Deterioration in physical condition/inactive (sedentary) lifestyle
Lack of physical activity is one of the most common causes of muscle weakness. If the muscles are not used, the fibers in the muscles are partially replaced by fat. Muscle atrophy eventually occurs: the muscles become less stocky and more flexible. Each fiber remains strong, but loses its ability to contract effectively.
You may feel your muscles becoming flabby and shrinking in size. This leads to mild fatigue when you try to do something, such as gardening or housework. If your muscles were trained, everything would be much easier for you. This condition is reversible but requires regular exercise. This becomes especially relevant with age.
Peak muscle development occurs between the ages of 20 and 30. It is in this age range that the greatest number of great athletes can be found. However, you can maintain muscle tone through regular exercise at any age. Many successful long-distance runners are over 40 years old and have trained their muscles to handle the long, extended periods of exercise that a marathon requires.
No matter what age you decide to improve your fitness, choose a reasonable exercise regimen and consult your doctor before starting. At the initial stage of training, you also need advice from trainers to prevent muscle injuries from too intense exercise.
Aging
As we age, our muscles lose strength and become weaker. Even though most people accept this as a natural consequence of age, they still sometimes feel frustrated when they are unable to do the things they were able to do when they were younger. However, even in old age, physical exercise can maintain and even increase muscle strength, with careful organization and safety of training.
As we age, it takes much longer to recover from injuries, as bones become thinner and break more easily. So monitoring the safety of physical exercise at an advanced age is of great importance.
Infections
Infections and diseases are among the most common causes of temporary muscle fatigue. The most vulnerable muscles are the thigh muscles. They can become inflamed during complications from the flu, and muscle weakness in this case can last for quite a long time.
Muscle weakness can also be caused by chronic fatigue syndrome or any illness characterized by high fever and muscle inflammation. However, there are a number of medical conditions that pose the highest risk of muscle weakness. These include: influenza, glandular fever virus, HIV, Lyme disease and hepatitis C.
Less common diseases that can cause muscle weakness are tuberculosis, malaria, syphilis, and polio.
Pregnancy
During and immediately after pregnancy, high levels of steroids in the blood, as well as a lack of adequate iron (anemia) can cause a feeling of muscle fatigue. During pregnancy, you should be especially careful when exercising, as the woman has to carry quite a lot of weight. This can lead to lower back pain if you do not adapt to the changed condition and carefully monitor your posture.
Permanent (chronic) diseases
Many chronic diseases often cause muscle weakness. In some cases, this is due to a reduction in blood and nutrients needed by the muscles.
Peripheral vascular diseases: Caused by narrowing of the arteries, usually due to increased cholesterol levels. Causes may include smoking or poor diet. Blood flow to the muscles slows down, and this becomes especially noticeable during physical activity that a person can no longer cope with. Sometimes pain may appear instead of weakness, but muscle weakness can also become a problem.

Diabetes. High blood sugar levels (and sometimes changes in salt levels) negatively affect the ability of muscles to perform their functions well. As diabetes progresses, the blood supply to the nerves is also impeded. The muscle fiber nerves lose sensitivity and the muscle fiber stops working. People with diabetes also have an increased tendency for their arteries to narrow.
Cardiovascular diseases, in particular, heart failure can lead to rapid muscle fatigue by reducing blood supply during physical activity. The heart is unable to provide the required amount of blood to the muscles, which results in muscle weakness.
Chronic lung diseases: Lung diseases such as chronic obstructive pulmonary disease (COPD) cause the body's ability to absorb oxygen to decrease. Muscles require a rapid supply of oxygen from the blood, especially during physical activity. Decreased oxygen consumption leads to mild fatigue. Over time, chronic lung disease can lead to muscle wasting, although this is mostly common in very severe cases when oxygen levels in the blood begin to drop.
Chronic kidney disease affects the entire body environment through salt imbalances in the body and through changes in calcium and vitamin D levels. Kidney disease also causes concentrations of toxic substances (toxins) in the blood because the kidneys are unable to process these toxins in a timely manner. All of this can lead to true muscle weakness as well as muscle fatigue.
Anemia(lack of red blood cells). It has many causes, including poor nutrition, blood loss, pregnancy, genetic diseases, infectious diseases and cancer. Anemia also reduces the blood's ability to carry oxygen to the muscles. Anemia develops rather slowly, and muscle fatigue and shortness of breath appear as the disease progresses.
Conditions affecting the “commands” of the brain to the muscles
Anxiety
Anxiety can cause muscle weakness. This is due to the increased activity of adrenaline in the body.
Depression
Depression can also cause general fatigue and muscle weakness. Note: anxiety and depression can cause a feeling of fatigue and muscle fatigue, but not true weakness.
Chronic pain
General effects on energy levels may be a result of chronic pain. It stimulates the body to produce chemicals that respond to pain and injury. These chemicals cause you to feel tired or tired.
With chronic pain, a person may experience not only muscle weakness, but also be unable to fully use the muscles due to pain and discomfort.
Muscle damage due to injury
There are many situations in which your muscles can become damaged. The most obvious is injury, dislocation, sprain (during physical activity and sports activities).
A common cause of injury can be an attempt to start doing exercises without proper warm-up and “warming up” the muscles. During a muscle injury, bleeding occurs within the damaged muscle tissue, followed by swelling and inflammation. This makes the muscles weak and painful when they function. Localized pain is the main symptom of a muscle injury, but weakness may also be present.
Medicines
Many medications can cause muscle weakness and muscle damage as a side effect or allergic reaction. It usually starts as fatigue, but can progress if medications are not stopped.
Some antibiotics and anti-inflammatory painkillers can cause a similar effect, and long-term use of oral steroids also causes muscle weakness and exhaustion. There are also a number of less commonly used medications that can cause muscle weakness and muscle damage. These include some heart medications, chemotherapy medications, HIV medications, interferon, and thyroid medications.
Other substances
Long-term alcohol use can cause weakness in the shoulder and hip muscles. Smoking can indirectly weaken muscles. Smoking causes narrowing of the arteries, which leads to peripheral vascular disease. Cocaine. Abuse of this drug causes noticeable muscle weakness, as with other psychoactive substances.
Sleep disorders
Sleep disturbances lead to a feeling of general fatigue, as well as muscle fatigue. Such disorders may include pure insomnia, anxiety, depression, chronic pain, restless leg syndrome, night shift work, and the need to stay awake due to the nightly whims of young children.

Many people face the problem of muscle weakness. And everyone strives to get rid of the feeling of discomfort, resorting to various methods. But it is not always possible to achieve the desired result. In this regard, the concept of therapy effectiveness arises. To implement this, it is necessary to establish the cause of muscle weakness.
What is muscle weakness and rapid muscle fatigue?
Muscle weakness is a common phenomenon that includes several concepts. These include dysfunction, tiredness and fatigue.Primary muscle weakness (true)– muscle dysfunction, decreased strength capabilities, a person’s inability to perform an action with the help of a muscle. This is also true for trained people.
Asthenia – muscle fatigue, exhaustion. The functional abilities of the muscles are preserved, but more effort is required to perform actions. It is typical for people suffering from insomnia, chronic fatigue and heart, kidney, and lung disease.
Muscle fatigue– rapid loss of the ability to normal muscle functioning and their slow recovery, which is often observed with asthenia. Characteristic of people with myotonic dystrophy.
Causes of muscle weakness in legs and arms
Almost everyone experiences muscle weakness and there are a number of reasons for this:- Neurological(stroke, multiple sclerosis, spinal cord and brain injuries, meningitis, polio, encephalitis, autoimmune Guillain-Barre disease).
- Lack of physical activity(muscle atrophy due to inactivity).
- Bad habits(smoking, alcohol, cocaine and other psychoactive substances).
- Pregnancy(lack of iron (Fe), increased physical activity, high hormonal levels).
- Old age(muscle weakening as a result of age-related changes).
- Injuries(damage to muscle tissue, sprain and dislocation).
- Medicines(some drugs or their overdose can cause muscle weakness - antibiotics, anesthetics, oral steroids, interferon and others).
- Intoxication(poisoning of the body with narcotic and other harmful substances).
- Oncology(malignant and benign tumors).
- Infections(tuberculosis, HIV, syphilis, complex influenza, hepatitis C, Lyme disease, glandular fever, polio and malaria).
- Cardiovascular diseases(inability to provide the muscles with the required amount of blood).
- Endocrine pathologies(diabetes mellitus, thyroid disorders, electrolyte imbalance).
- Spinal problems(curvature, osteochondrosis, intervertebral hernia).
- Genetic diseases(myasthenia gravis, myotonic dystrophy and muscle dystrophy).
- Damage to the sciatic or femoral nerve(muscle weakness in only one limb).
- Chronic lung diseases(COPD, lack of oxygen) and kidneys(salt imbalance, release of toxins into the blood, lack of vitamin D and calcium (Ca)).
Lack of sleep, dehydration, anemia, anxiety and depression can also lead to muscle weakness.
Symptoms of muscle weakness
A feeling of weakness in the arms, legs or body is often accompanied by drowsiness, fever, chills, impotence and apathy. Each of the symptoms informs about serious problems of the body as a whole.There are frequent manifestations of muscle weakness at elevated temperatures, which are a consequence of inflammatory processes - bronchitis, common colds, cold kidneys, etc. The slightest jump in temperature leads to incorrect functioning of metabolic processes, and the body gradually loses its functional abilities. Therefore, at a temperature, fatigue and muscle weakness are observed, and not only in the limbs.
Manifestations of the disease are also characteristic of intoxication. Poisoning of the body can be caused by stale food, hepatitis, a certain virus, etc.
In addition, weakness and drowsiness can be a dangerous pathology of an allergic and infectious nature. Brucellosis is considered the most dangerous, often depriving its carrier of life.
There is weakness in the muscles and in cases of blood infections - leukemia and myeloid leukemia. The same symptoms appear in rheumatism.
Somatic diseases also contribute to the formation of the main symptom, including amyloidosis, Crohn's disease (associated with digestion), renal failure and cancer.
Endocrine system disorders lead to muscle weakness, as do epilepsy, neurasthenia, depression and neurosis.
Myasthenia. How to overcome muscle weakness (video)
The video talks about muscle weakness, what it is and the reasons for its occurrence. How to deal with such a phenomenon as myasthenia gravis. And what are the consequences of the lack of timely therapy?
Muscle weakness with VSD, depression, neurosis
VSD (vegetative-vascular dystonia) manifests itself in certain diseases, including hormonal disorders and mitochondrial pathology. A number of symptoms develop against the background of autonomic dysfunction of the vascular system and cardiac muscle. This is what leads to poor circulation.As a result, the limbs do not receive enough oxygen and red blood cells. It is difficult to remove carbon dioxide from the body. This causes severe weakness, or even body aches, and with advanced VSD, fainting.
The best way to eliminate the disease is physical activity. To normalize metabolic processes, lactic acid is needed, the production of which stops with low physical activity. Doctors recommend moving more - walking, running, doing daily warm-ups.
Drug and traditional therapies are not only ineffective, but are also fraught with complications due to muscle weakness due to VSD.
Depression against the background of disappointment, loss, bad mood and other difficulties can drive you into a melancholic state. Symptoms may include lack of appetite, nausea, dizziness, strange thoughts, pain in the heart - all this manifests itself in the form of weakness, including muscle weakness.
For depression, the following procedures will help overcome muscle weakness:
- positive emotions;
- help from a psychotherapist (for severe depression).
Muscle weakness in a child
The occurrence of muscle weakness is typical not only for adults, but also for children. Often they experience a time difference between the nerve signal and the subsequent muscle response. And this explains the behavior of babies who are unable to hold their body or limbs in a fixed position for a long time.Causes of muscle weakness in a child may include:
- myasthenia gravis;
- congenital hypothyroidism;
- botulism;
- rickets;
- muscular dystrophy and spinal atrophy;
- blood poisoning;
- consequences of drug therapy;
- excess vitamin D;
- Down syndrome (Prader-Willi, Marfan).
As muscle weakness develops, regardless of its cause, the child's appearance changes.
Primary symptoms of muscle weakness in a child:
- using limbs as support by placing them to the sides;
- involuntary placement of the arms, slipping when lifting by the armpits (the child cannot hang onto the parent’s arms by the armpits);
- inability to hold the head straight (lowering, throwing back);
- lack of flexion of the limbs during sleep (arms and legs are located along the body);
- general delay in physical development (inability to hold objects, sit upright, crawl and roll over).
- Special exercises.
- Proper nutrition.
- Development of coordination of movements, as well as fine motor skills.
- Development of posture and formation of gait.
- Physiotherapeutic procedures.
- Medicines (anti-inflammatory and muscle tonic).
- Sometimes a trip to a speech therapist (to improve speech).
You can restore muscle function in a child with any diagnosis, but only if you consult a doctor in a timely manner.
When to see a doctor
Often muscle weakness is a consequence of overwork or temporary weakness. But in some cases it may indicate the presence of a serious illness. And if weakness is periodic or constant, you should immediately visit a doctor.Specialists such as a therapist, neurologist, endocrinologist, surgeon and others will help you find out the cause of discomfort. You will also need to take some tests and undergo a series of examinations.
If muscle weakness is rare, there is no sensation of pain or numbness, and it goes away quickly, doctors recommend doing the following on your own:
- balance your diet;
- drink more purified water;
- take walks in the fresh air more often.
Diagnostics
Before prescribing effective treatment, specialists carry out the necessary diagnostic measures, including instrumental and laboratory examination. For a patient with muscle weakness, the following procedures are provided:- Consultation with a neurologist.
- Blood test (general and antibody).
- Cardiogram of the heart.
- Examination of the thymus gland.
- Electromyography (determining the amplitude of muscle potential).
Treatment
If muscle weakness is caused by overwork, it is enough to rest your limbs after strength training or a long walk (especially in uncomfortable shoes). In other cases, appropriate therapy may be prescribed:- muscle development through special exercises;
- medications to improve brain activity and blood circulation;
- drugs that remove toxins from the body;
- antibacterial agents for infections in the spinal cord or brain;
- increasing neuromuscular activity through special medications;
- elimination of the consequences of poisoning;
- surgical intervention aimed at removing tumors, ulcers and hematomas.
Increasing weakness on the left side may indicate a stroke.
Traditional methods
You can also combat muscle weakness at home. To do this, you need to take the following steps:- Take 2-3 tbsp. l. grape juice a day.
- Drink 1 glass of decoction of unpeeled potatoes three times a week.
- Every evening use motherwort infusion (10%) in volume? glasses.
- Make a mixture of walnuts and wild honey (proportions 1 to 1), eat every day (course – several weeks).
- Include protein foods with low fat content (fish, poultry) in your diet.
- Increase your consumption of foods containing iodine.
- 30 minutes before meals, drink a mixture consisting of 2 tbsp. l. sugar, ? glass of cranberry juice and 1 glass of lemon juice.
- Take tinctures of ginseng, aralia or lemongrass 30 minutes before meals.
- Take relaxing baths with the addition of essential oils or citrus fruits (water temperature should vary between 37-38 degrees Celsius).
- 2 tbsp. juniper (berries) and 1 glass of boiling water will calm the nervous system and restore muscle tone.
- Instead of water, drink a chilled infusion made from 1 tbsp. oat straw and 0.5 liters of boiling water.
Possible consequences and complications
Lack of physical activity provokes a decrease in muscle tone and entails a number of other problems. These include:- deterioration of coordination;
- slowing down metabolism (see also -);
- decreased immunity (susceptibility to viral diseases);
- problems with the heart muscle (tachycardia, bradycardia and hypotension);
- swelling of the limbs;
- gaining excess weight.
Prevention
To avoid problems associated with muscle fatigue, it is recommended to follow a few simple rules:- Adhere to proper nutrition (including foods rich in protein and calcium, cereals, vegetables, herbs, honey, vitamins) and lifestyle.
- Dedicate enough time to work, rest and exercise.
- Monitor blood pressure.
- Avoid stress and excessive fatigue.
- Be in the fresh air.
- Give up bad habits.
- Contact your doctor if serious problems occur.
In old age, it is advisable to give up a sedentary lifestyle, devote more time to therapeutic exercises and walks in the fresh air, and also not to neglect massage therapy.
The video discusses a congenital disease - dysplasia, characterized by leg and hand weakness, frequent dizziness and high blood pressure. Special exercises and proper breathing to eliminate weakness.Muscle weakness is a phenomenon inherent in everyone. Everyone can fight the disease, especially in cases of overwork and lack of physical activity. But for more serious reasons, you will need the help of a specialist. He will diagnose the problem and prescribe effective treatment. Follow the recommendations, and myasthenia gravis will bypass you.

Muscle weakness syndrome is called myasthenia gravis - a pathological process of an autoimmune nature that reduces muscle contractility. This disease can develop as a result of damage to the anatomical components of the limbs (vessels, bones, articular surfaces, nerves). Muscle weakness can develop in both the arms and legs. In this section we will look at the main causes of muscle weakness in the legs and arms and their treatment.
Main symptoms of myasthenia gravis:
- 1. Decreased muscle strength. The measurement can be made either using a special tool - a dynamometer, or the hands of an examining doctor. To assess muscle strength without an instrument, the doctor simultaneously shakes the patient's two hands while assessing the symmetry of muscle tension.
- 2. Difficulty performing routine tasks (walking, climbing stairs, holding a mug in your hands, writing with a pen, carrying moderately heavy packages);
- 3. In addition to decreased strength in a particular limb, blepharoptosis (drooping of the eyelid), difficulty swallowing, speaking, or chewing may occur.
Causes of muscle weakness in the legs
This syndrome in the legs most often develops due to the following reasons:
- 1. atherosclerosis of the vessels of the lower extremities;
- 2. pinching of the innervating nerve;
- 3. varicose veins of the lower extremities;
- 4. wearing uncomfortable shoes or flat feet;
- 5. damage to blood vessels or muscles by infectious agents;
- 6. metabolic disorders (damage to the thyroid gland);
- 7. calcium deficiency in the body.
Causes of weakness in the hands
The syndrome develops much less frequently in the arms than in the legs. Its main reasons:
- 1. atherosclerosis of the vessels of the upper extremities;
- 2. pinching, injury, hypothermia of one of the nerves;
- 3. sudden changes in blood pressure;
- 4. stroke;
- 5. infectious damage to blood vessels and muscles of the upper extremities;
- 6. metabolic disorders;
- 7. lack of calcium in the body.
Treatment of muscle weakness
Severe flaccidity in the legs and arms causes discomfort to the patient. To the question “How to treat muscle weakness?” experts answer that there are several methods: conservative (medicinal) method, surgery and physiotherapy. If the cause of weakness lies in infection, then antibacterial, anti-inflammatory, and antiviral drugs are used. Additionally, physiotherapeutic procedures are prescribed that improve blood flow in the area of the necessary muscles.
Treatment depends on the cause that causes it (injuries, infections, genetic, autoimmune processes, consequences of stroke, etc.). If muscle weakness occurs, you should immediately contact a specialist in neuromuscular pathology.
Why does weakness occur in the arms and legs? The reasons for this condition will be discussed in this article. We will also tell you about how to treat this pathology and which specialist to contact.

General information
Quite a large number of people periodically experience weakness in the muscles of their arms and legs. The reasons for this phenomenon should only be identified by an experienced specialist. After all, unexpected and growing weakness in the limbs, when the legs are “filled with lead” and the hands are not able to hold even a cup of coffee, may indicate the development of a serious illness.
Most often, the condition in question is transient and disappears very quickly. But is it possible to neglect this pathological phenomenon? Doctors say that if you develop severe or even transient weakness in the limbs, you should definitely undergo a medical examination.
Weakness in the arms and legs, dizziness: main causes
What could cause the condition in question? In most cases, this phenomenon is a sign of a neurological disorder, which is accompanied by a violation of neuromuscular impulses.
Why else might weakness in the arms and legs occur? The causes of this condition are often associated with electrolyte imbalance or metabolism. As a rule, this phenomenon is observed when following strict diets or violating the drinking regime (for example, when there is a lack of fluid in the human body).
In addition, the development of weakness in the limbs can occur due to impaired functioning of the kidneys, liver and other organs of the digestive system.
Other reasons
Why does weakness develop in the arms and legs? The causes of this condition are associated with the presence of:
- cervical spondylosis;
- cervical osteochondrosis;
- inflammatory or traumatic lesions of the shoulder, scapular or wrist areas;
- shoulder arthritis.
Most common reasons
Severe weakness in the arms and legs, the causes of which were described above, causes great discomfort to the patient. After all, such a state can take a person by surprise (for example, on the street, while driving a vehicle, at work, and so on). Therefore, it is imperative to identify the cause of this phenomenon.
Above we told you about why weakness in the arms and legs may occur. The reasons we have listed are far from the only ones. According to experts, this condition can also occur in the presence of diseases and conditions such as:
- lumbar osteochondrosis;
- lumbar hernia in the spine;
- lumbago;
- menstruation, pregnancy:
- menopause;
- hormonal changes (for example, during puberty and before menstruation);
- endocrine diseases (pathologies of the thyroid gland, diabetes);
- experiences, nervous stress, chronic fatigue syndrome.
It should also be said that there can be many reasons for the development of weakness in the limbs. Therefore, it is extremely important to diagnose all possible pathologies.
Muscle weakness
Muscle weakness in the arms and legs, the causes of which should only be diagnosed by a doctor, is treated in different ways. But before starting therapy, you need to make sure whether this symptom is the only one, or whether it is accompanied by some pain, sensory disturbances, numbness, and so on. For example, arthritis, in which there is obvious weakness in the limbs, is almost always characterized by discomfort in the joints, but dermatomyositis is often accompanied by skin lesions.
True weakness in the muscles of the legs and arms usually occurs symmetrically. Moreover, it is completely independent of physical activity. As a rule, this condition is observed first in the lower extremities, and then gradually moves to the arms.
Muscle weakness: what is it associated with?
What causes muscle weakness in the arms and legs? The reasons for this unpleasant phenomenon may be hidden in the development of many diseases. However, most often this condition indicates pathologies such as:
- diabetes;
- protein deficiency in the body;
- electrolyte metabolism disorder;
- anemia or hypovitaminosis;
- an inflammatory process occurring in any organ;
- dehydration of the body;
- presence of rheumatoid arthritis;
- penetration of infection into the body;
- neurological pathologies;
- exposure to toxic substances or poisoning;
- misuse of certain medications;
- diseases of the thyroid gland with metabolic disorders;
- asthenic syndrome;
- emotional overload and stressful situations experienced.
Weakness in the left arm and leg: causes of development
As a rule, when weakness develops in the left arm and leg, experts talk about a stroke, that is, an acute cerebrovascular accident. Indeed, a clear sign of such a pathology is precisely the numbness of one half of the body (most often the left). Such cases occur quite often. However, it should be noted that this is far from the only ailment that is expressed in the impotence of the limbs. So why else might weakness in the arms and legs and drowsiness occur? The reasons for this condition are often hidden in:
- cardiopathologies (that is, diseases of the coronary vessels and heart);
- vegetative-vascular dystonia, obliterating endarteritis;
- diseases of the left kidney, including the development of a tumor process in this organ;
- diseases of the spleen;
- obliterating atherosclerosis, thromboangiitis;
- diseases of the spine, including its curvature, disc protrusion, hernia and tumor process.
It must also be said that it is impossible to diagnose all of these diseases without special research methods. Therefore, if weakness in the limbs occurs, you should contact a doctor, who is obliged to refer the patient for further examination in order to identify the exact cause of the pathology in question. As for a stroke, if you suspect it, you should urgently visit a specialist.
Weakness in the limbs accompanied by trembling
Trembling is the frequent and involuntary contraction of the muscles of the legs or arms. Very often this condition is accompanied by weakness. It is quite difficult to identify the cause of this phenomenon. At the same time, experts argue that such a condition can be essential, physiological, cerebellar and parkinsonian.
Essential tremors and weakness of muscle tissue can be hereditary, and are also often associated with the patient’s age. This condition intensifies with physical activity. At the same time, it is not dangerous, but it significantly affects a person’s quality of life.
Physiological tremors and weakness in the limbs are the most common condition. As a rule, it is associated with anxiety, nervous overexcitation, fear, hypothermia, fatigue, certain diseases of the nervous system and endocrine system, as well as withdrawal syndrome. It should also be said that such tremors often appear after long exposure to the sun or taking large doses of caffeine.
Weakness and cerebellar tremors develop when the cerebellum is damaged. Thus, this may be a sign of congenital cerebellar ataxia, multiple sclerosis, and so on.
Parkinsonian tremors and weakness indicate the presence of Parkinson's disease.
Weakness in the limbs accompanied by numbness
A condition in which there is weakness in the limbs, as well as numbness, may indicate an impending cold or other infectious disease. Also, a similar phenomenon is often observed with poor sleep, insufficient nutrition and overwork.
If the limbs gradually become numb and weakness appears in them (for example, over the course of a week, a month or even a year), then we can talk about damage to the spinal cord, brain or neuromuscular system. In such cases, a medical examination is necessary.
It must also be said that the symptoms in question very often indicate diseases of the musculoskeletal system, including intervertebral discs, spinal column, bones and joints. A similar condition can also occur after a back injury.
Who to contact and how to treat?
Now you know why weakness occurs in the legs and arms. The causes and treatment of this pathology are discussed in this article.
If weakness in the limbs suddenly develops, the patient needs to lie down and ensure maximum peace and relaxation. You can also sit quietly for about 20 minutes.
In some cases, the normal state can be restored by taking some sedative drug (for example, Novopassit, valerian extract, Fitosed, and so on).
If you have weakness in your limbs, you should never drink alcohol or smoke. In this case, it is better to brew a soothing tea or make an infusion with mint, chamomile, honey or linden.
If the cause of this condition is a serious illness, then you should consult a doctor. Subspecialists such as a neurologist, traumatologist, psychologist and endocrinologist will help you understand the situation.
Many people face the problem of muscle weakness. And everyone strives to get rid of the feeling of discomfort, resorting to various methods. But it is not always possible to achieve the desired result. In this regard, the concept of therapy effectiveness arises. To implement this, it is necessary to establish the cause of muscle weakness.
What is muscle weakness and rapid muscle fatigue?
Muscle weakness is a common phenomenon that includes several concepts. These include dysfunction, tiredness and fatigue.
Primary muscle weakness (true)– muscle dysfunction, decreased strength capabilities, a person’s inability to perform an action with the help of a muscle. This is also true for trained people.
Asthenia – muscle fatigue, exhaustion. The functional abilities of the muscles are preserved, but more effort is required to perform actions. It is typical for people suffering from insomnia, chronic fatigue and heart, kidney, and lung disease.
Muscle fatigue– rapid loss of the ability to normal muscle functioning and their slow recovery, which is often observed with asthenia. Characteristic of people with myotonic dystrophy.
Causes of muscle weakness in legs and arms
Almost everyone experiences muscle weakness and there are a number of reasons for this:
- Neurological(stroke, multiple sclerosis, spinal cord and brain injuries, meningitis, polio, encephalitis, autoimmune Guillain-Barre disease).
- Lack of physical activity(muscle atrophy due to inactivity).
- Bad habits(smoking, alcohol, cocaine and other psychoactive substances).
- Pregnancy(lack of iron (Fe), increased physical activity, high hormonal levels).
- Old age(muscle weakening as a result of age-related changes).
- Injuries(damage to muscle tissue, sprain and dislocation).
- Medicines(some drugs or their overdose can cause muscle weakness - antibiotics, anesthetics, oral steroids, interferon and others).
- Intoxication(poisoning of the body with narcotic and other harmful substances).
- Oncology(malignant and benign tumors).
- Infections(tuberculosis, HIV, syphilis, complex influenza, hepatitis C, Lyme disease, glandular fever, polio and malaria).
- Cardiovascular diseases(inability to provide the muscles with the required amount of blood).
- Endocrine pathologies(diabetes mellitus, thyroid disorders, electrolyte imbalance).
- Spinal problems(curvature, osteochondrosis, intervertebral hernia).
- Genetic diseases(myasthenia gravis, myotonic dystrophy and muscle dystrophy).
- Damage to the sciatic or femoral nerve(muscle weakness in only one limb).
- Chronic lung diseases(COPD, lack of oxygen) and kidneys(salt imbalance, release of toxins into the blood, lack of vitamin D and calcium (Ca)).
Lack of sleep, dehydration, anemia, anxiety and depression can also lead to muscle weakness.
Symptoms of muscle weakness
A feeling of weakness in the arms, legs or body is often accompanied by drowsiness, fever, chills, impotence and apathy. Each of the symptoms informs about serious problems of the body as a whole.
There are frequent manifestations of muscle weakness at elevated temperatures, which are a consequence of inflammatory processes - bronchitis, common colds, cold kidneys, etc. The slightest jump in temperature leads to incorrect functioning of metabolic processes, and the body gradually loses its functional abilities. Therefore, at a temperature, fatigue and muscle weakness are observed, and not only in the limbs.
Manifestations of the disease are also characteristic of intoxication. Poisoning of the body can be caused by stale food, hepatitis, a certain virus, etc.
In addition, weakness and drowsiness can be a dangerous pathology of an allergic and infectious nature. Brucellosis is considered the most dangerous, often depriving its carrier of life.
There is weakness in the muscles and in cases of blood infections - leukemia and myeloid leukemia. The same symptoms appear in rheumatism.
Somatic diseases also contribute to the formation of the main symptom, including amyloidosis, Crohn's disease (associated with digestion), renal failure and cancer.
Endocrine system disorders lead to muscle weakness, as do epilepsy, neurasthenia, depression and neurosis.
Myasthenia. How to overcome muscle weakness (video)
The video talks about muscle weakness, what it is and the reasons for its occurrence. How to deal with such a phenomenon as myasthenia gravis. And what are the consequences of the lack of timely therapy?
Muscle weakness with VSD, depression, neurosis
VSD (vegetative-vascular dystonia) manifests itself in certain diseases, including hormonal disorders and mitochondrial pathology. A number of symptoms develop against the background of autonomic dysfunction of the vascular system and cardiac muscle. This is what leads to poor circulation.
As a result, the limbs do not receive enough oxygen and red blood cells. It is difficult to remove carbon dioxide from the body. This causes severe weakness, dizziness or even body aches, and with advanced VSD, fainting.
The best way to eliminate the disease is physical activity. To normalize metabolic processes, lactic acid is needed, the production of which stops with low physical activity. Doctors recommend moving more - walking, running, doing daily warm-ups.
Drug and traditional therapies are not only ineffective, but are also fraught with complications due to muscle weakness due to VSD.
Depression against the background of disappointment, loss, bad mood and other difficulties can drive you into a melancholic state. Symptoms may include lack of appetite, nausea, dizziness, strange thoughts, pain in the heart - all this manifests itself in the form of weakness, including muscle weakness.
For depression, the following procedures will help overcome muscle weakness:
- proper nutrition;
- good sleep;
- contrast shower;
- positive emotions;
- help from a psychotherapist (for severe depression).
Neurosis is characterized by nervous exhaustion of the body through prolonged stress. The disease is often accompanied by VSD. In addition to physical weakness, there is also mental weakness. To eliminate the consequences, a set of measures is required, including a change in lifestyle, giving up bad habits, playing sports, walking in the fresh air, as well as drug therapy and a course of psychotherapy with a specialist.
Muscle weakness in a child
The occurrence of muscle weakness is typical not only for adults, but also for children. Often they experience a time difference between the nerve signal and the subsequent muscle response. And this explains the behavior of babies who are unable to hold their body or limbs in a fixed position for a long time.
Causes of muscle weakness in a child may include:
- myasthenia gravis;
- congenital hypothyroidism;
- botulism;
- rickets;
- muscular dystrophy and spinal atrophy;
- blood poisoning;
- consequences of drug therapy;
- excess vitamin D;
- Down syndrome (Prader-Willi, Marfan).
As muscle weakness develops, regardless of its cause, the child's appearance changes.
Primary symptoms of muscle weakness in a child:
- using limbs as support by placing them to the sides;
- involuntary placement of the arms, slipping when lifting by the armpits (the child cannot hang onto the parent’s arms by the armpits);
- inability to hold the head straight (lowering, throwing back);
- lack of flexion of the limbs during sleep (arms and legs are located along the body);
- general delay in physical development (inability to hold objects, sit upright, crawl and roll over).
Treatment depends on the cause and extent of muscle dysfunction. Specialists such as an orthopedist, physiotherapist, neurologist and others may prescribe the following treatment:
- Special exercises.
- Proper nutrition.
- Development of coordination of movements, as well as fine motor skills.
- Development of posture and formation of gait.
- Physiotherapeutic procedures.
- Medicines (anti-inflammatory and muscle tonic).
- Sometimes a trip to a speech therapist (to improve speech).
You can restore muscle function in a child with any diagnosis, but only if you consult a doctor in a timely manner.
When to see a doctor
Often muscle weakness is a consequence of overwork or temporary weakness. But in some cases it may indicate the presence of a serious illness. And if weakness is periodic or constant, you should immediately visit a doctor.
Specialists such as a therapist, neurologist, endocrinologist, surgeon and others will help you find out the cause of discomfort. You will also need to take some tests and undergo a series of examinations.
If muscle weakness is rare, there is no sensation of pain or numbness, and it goes away quickly, doctors recommend doing the following on your own:
- balance your diet;
- drink more purified water;
- take walks in the fresh air more often.
For other manifestations of muscle weakness, you must make an appointment with a specialist to quickly eliminate the possible disease. And self-medication in such cases is contraindicated.
Diagnostics
Before prescribing effective treatment, specialists carry out the necessary diagnostic measures, including instrumental and laboratory examination. For a patient with muscle weakness, the following procedures are provided:
- Consultation with a neurologist.
- Blood test (general and antibody).
- Cardiogram of the heart.
- Examination of the thymus gland.
- Electromyography (determining the amplitude of muscle potential).
Treatment
If muscle weakness is caused by overwork, it is enough to rest your limbs after strength training or a long walk (especially in uncomfortable shoes). In other cases, appropriate therapy may be prescribed:
- muscle development through special exercises;
- medications to improve brain activity and blood circulation;
- drugs that remove toxins from the body;
- antibacterial agents for infections in the spinal cord or brain;
- increasing neuromuscular activity through special medications;
- elimination of the consequences of poisoning;
- surgical intervention aimed at removing tumors, ulcers and hematomas.
Increasing weakness on the left side may indicate a stroke.
Traditional methods
You can also combat muscle weakness at home. To do this, you need to take the following steps:
- Take 2-3 tbsp. l. grape juice a day.
- Drink 1 glass of decoction of unpeeled potatoes three times a week.
- Every evening use motherwort infusion (10%) in volume? glasses.
- Make a mixture of walnuts and wild honey (proportions 1 to 1), eat every day (course – several weeks).
- Include protein foods with low fat content (fish, poultry) in your diet.
- Increase your consumption of foods containing iodine.
- 30 minutes before meals, drink a mixture consisting of 2 tbsp. l. sugar, ? glass of cranberry juice and 1 glass of lemon juice.
- Take tinctures of ginseng, aralia or lemongrass 30 minutes before meals.
- Take relaxing baths with the addition of essential oils or citrus fruits (water temperature should vary between 37-38 degrees Celsius).
- 2 tbsp. juniper (berries) and 1 glass of boiling water will calm the nervous system and restore muscle tone.
- Instead of water, drink a chilled infusion made from 1 tbsp. oat straw and 0.5 liters of boiling water.
Possible consequences and complications
Lack of physical activity provokes a decrease in muscle tone and entails a number of other problems. These include:
- deterioration of coordination;
- slowing down metabolism (see also - how to speed up metabolism);
- decreased immunity (susceptibility to viral diseases);
- problems with the heart muscle (tachycardia, bradycardia and hypotension);
- swelling of the limbs;
- gaining excess weight.
Prevention
To avoid problems associated with muscle fatigue, it is recommended to follow a few simple rules:
- Adhere to proper nutrition (including foods rich in protein and calcium, cereals, vegetables, herbs, honey, vitamins) and lifestyle.
- Dedicate enough time to work, rest and exercise.
- Monitor blood pressure.
- Avoid stress and excessive fatigue.
- Be in the fresh air.
- Give up bad habits.
- Contact your doctor if serious problems occur.
In old age, it is advisable to give up a sedentary lifestyle, devote more time to therapeutic exercises and walks in the fresh air, and also not to neglect massage therapy.
The video discusses a congenital disease - dysplasia, characterized by leg and hand weakness, frequent dizziness and high blood pressure. Special exercises and proper breathing to eliminate weakness.
Muscle weakness is a phenomenon inherent in everyone. Everyone can fight the disease, especially in cases of overwork and lack of physical activity. But for more serious reasons, you will need the help of a specialist. He will diagnose the problem and prescribe effective treatment. Follow the recommendations, and myasthenia gravis will bypass you.
Weakness in the muscles of the arms and legs
If you complain about weakness of the muscles of the arms and legs, you should first make sure whether this symptom is the only one or is accompanied by pain, numbness, sensory disturbances, etc. For example, arthritis, which is accompanied by weakness of the limbs, is almost always characterized by pain in the joints, and dermatomyositis - damage to the skin.
True muscle weakness, as a rule, occurs symmetrically and is independent of physical activity. Most often, weakness begins in the lower extremities, gradually moving to the arms.
Muscle weakness can be a consequence of many diseases and conditions of the body. Perhaps most often, such weakness indicates the following pathologies:
- about protein deficiency in the body;
- about the inflammatory process in any organ;
- about the penetration of infection into the body;
- about exposure to toxic substances or poisoning;
- about dehydration of the body;
- about a disorder of electrolyte metabolism;
- about anemia or hypovitaminosis;
- about diabetes;
- about thyroid diseases with metabolic disorders;
- about neurological pathology;
- about the presence of rheumatoid arthritis;
- about the incorrect use of certain medications;
- about asthenic syndrome;
- about emotional overload and stressful situations experienced.
In any case, to determine the cause of the disease, you should consult a doctor, since treatment must be aimed at eliminating the underlying disease.
Weakness of the left arm and leg
Usually, if weakness of the left arm and leg appears, the first thing to suspect is a stroke - an acute cerebrovascular accident. Indeed, a characteristic symptom of this pathology is numbness of one half of the body, in this case the left. This is quite likely, but not the only factor that can result in limb weakness. So what else could cause this condition?
- vegetative-vascular dystonia, obliterating endarteritis;
- cardiopathology (diseases of the heart and coronary vessels);
- disease of the left kidney, including a tumor process;
- spleen disease;
- obliterating atherosclerosis or thromboangiitis;
- diseases of the spine, including curvature of the spinal column, disc protrusion, hernia, tumor process in the spine.
It is almost impossible to diagnose such diseases without special research methods. Therefore, the doctor must send the patient for further examination in order to accurately identify the possible cause of the weakness of the left arm and leg. If you suspect a stroke, you should consult a doctor immediately.
Trembling hands and weakness in legs
Limb trembling is an involuntary frequent contraction of various muscle groups in the arms or legs. The condition when hands shake and weakness appears in the legs is common and is not always the result of any one cause. This condition can be physiological, essential, parkinsonian and cerebellar. Let's consider these states in more detail.
- Essential tremors and muscle weakness may be hereditary or may be age-related. This pathology intensifies with physical activity: it is not dangerous, but it significantly affects the patient’s quality of life.
- Parkinsonian tremors and muscle weakness are commonly present in Parkinson's disease and are usually accompanied by or without hypokinesia. Symptoms most often occur at rest.
- Cerebellar tremors and muscle weakness occur when the cerebellum, which controls movement, is damaged. This may be a manifestation of multiple sclerosis, congenital cerebellar ataxia, etc.
- Physiological hand tremors and weakness in the legs are the most common condition. It is associated with nervous overexcitation, anxiety, fear, fatigue, hypothermia, withdrawal syndrome and some diseases of the nervous and endocrine systems. Often, tremors in the hands and weakness in the legs appear after taking large doses of caffeine, or after prolonged exposure to the sun.
Numbness and weakness in the arms and legs
A condition in which a person feels weak and their arms and legs are numb may be a sign of an impending cold or other infectious disease. Poor sleep, insufficient nutrition, and overwork can also become indirect causes of this condition.
If numbness of the limbs and weakness appear gradually, over a week or a month or even a year, damage to the brain or spinal cord, as well as the neuromuscular system, can be suspected. In such situations, a thorough examination is necessary, since all the causes are quite serious and require careful medical supervision.
Numbness of the arms and legs combined with weakness may be a sign of a disease of the musculoskeletal system: the spinal column, intervertebral discs, joints and bones. It can also be a consequence of a long-standing back injury.
In addition, you need to remember the most common reason leading to numbness and weakness of the limbs (usually one-sided) is a stroke. A stroke develops quite quickly as a result of a violation of the integrity of the vascular wall or cessation of blood flow in any of the vessels of the brain.
Sudden numbness in the arms and legs combined with weakness, headache or dizziness is a characteristic sign of a brain disease. This is more than enough reason to immediately consult a doctor.
Severe muscle weakness manifested by severe fatigue and muscle weakness. This symptom is often one of the first signs hyperparathyroidism.
How does severe muscle weakness manifest?
Muscle fatigue characterized by a pronounced decrease in strength in one muscle or several at once. It is very important to clearly distinguish between muscle weakness and the general state of fatigue, weakness and lethargy. Chronic muscle fatigue is felt both in a specific limb and in any other area of the body.
In medicine it is determined objective(in this case, the study confirms the fact of a decrease in muscle strength) and subjective(a person feels tired in a muscle, but the results of the study show that strength is preserved) muscle weakness. Classification related to the affected area is practiced. Varies localized And generalized forms of this disease.
This condition is characterized by rapid fatigue of the striated muscles, which will determine the functioning of the human musculoskeletal system. Quite often a person, feeling weakness in the muscles of the arms or legs, only suffers from general fatigue, so the doctor needs to be very careful in the process of making a diagnosis.
Often muscle weakness in the arms or muscle weakness in the legs is a symptom myasthenia gravis- a disease caused by autoimmune attacks of the body. This disease usually appears periodically. Exacerbations of the disease alternate with periods of remission. In patients with myasthenia gravis, the muscular system loses the ability to contract, as the person gradually loses muscle strength. In most cases, the disease affects young and middle-aged women, as well as men over 50 years of age.
Proximal muscle weakness It occurs primarily in the arms and legs, but sometimes it can occur in both the upper and lower extremities.
A patient with this symptom often finds it difficult to move long distances or walk up stairs. In some cases, it is even difficult for such people to stand and sit. Often their gait takes on the characteristics of a so-called “duck” walk - they walk as if rolling from side to side. If the muscles of the foot are affected, then over time the person develops flat feet. Subsequently, a person may develop hyperparathyroidism- a disease associated with too active hormone production parathyroid hormone, which subsequently leads to the development hypercalcemia. In such patients, in addition to muscle weakness, there are disorders of the kidneys, gastrointestinal tract, and signs of changes in the nervous system.
Why does severe muscle weakness occur?
The causes of muscle weakness are associated with various diseases and factors affecting the human body. Severe muscle weakness in older people and in younger patients can develop against the background of both muscular and mental diseases. Causes of muscle weakness in the legs and arms are often associated with the development of myasthenia gravis. This disease is of an autoimmune nature. Myasthenia gravis affects synapses– places where nerves and muscles connect. Consequently, this process leads to innervation. Myasthenic syndrome often develops against the background thymus tumors, hyperplasia, as well as for some diseases of the human nervous system. Symptoms of muscle weakness associated with myasthenia gravis are more common in women. Sometimes this illness is a consequence of severe stress or an infectious disease. Muscle weakness is sometimes noted in children. As a rule, the manifestation of this symptom indicates the development muscle tissue dystrophy. A child with this symptom often has various types of disturbances in the functions of the central nervous system, muscle development defects, or the presence of certain genetic disorders.
However, the causes of weakness in the arms and legs are not always associated with myasthenia gravis. If a person feels normal, but at the same time notices severe fatigue and weakness in the legs, then in some cases the manifestation of this symptom is explained by overwork, constant work in a standing position, or even regularly wearing not very comfortable shoes. In this case, the patient suffers from fatigue, rumbling in the legs, and fatigue. This symptom is most often observed in older people, but women who prefer high-heeled shoes often report fatigue and a feeling of weakness in the lower extremities. In addition, this phenomenon may be a sign Varicose veins, spinal diseases.
Weakness of the muscles of the neck, back, pelvic floor, limbs, etc. manifests itself not only as a result of an independent autoimmune disease, but can also be a symptom of certain diseases and pathological conditions. Often, muscle weakness is observed with a constant protein deficiency, with the active development of inflammatory processes or infectious diseases, with intoxication or dehydration of the body. Patients with diabetes mellitus, thyroid diseases. Muscle pain and weakness are a symptom of severe poisoning, an overdose of certain medications. Weakness in the leg muscles is characteristic of rheumatoid arthritis. It should also be taken into account that in some cases the causes of muscle weakness are associated with the development asthenic syndrome. A person sometimes notices a pronounced feeling of fatigue in the calf muscles after experiencing stress or serious emotional stress.
Weakness of the heart muscle leads to the development heart failure and occurs against the background of many cardiovascular pathologies.
How to get rid of severe muscle weakness?
Treatment of muscle weakness always depends on the underlying disease and is prescribed only after a complete diagnosis and determination of the cause of the disease. For patients who suffer from myasthenia gravis, it is very important to establish a diagnosis as early as possible, since the disease is more effectively treated at an early stage. In the diagnostic process, both laboratory and instrumental research methods are practiced.
During therapy, the doctor prescribes symptomatic treatment, as well as a course of physiotherapeutic procedures that help restore the normal state of a person’s muscles. However, as a rule, the disease has a chronic course, so it is impossible to completely get rid of the symptoms. The doctor prescribes medications and their dosage regimen for patients with myasthenia gravis individually, since it is necessary to take into account the characteristics of the symptoms and course of the disease. Most patients are prescribed drugs that block the destroyers acetylcholine- a substance that is formed in the body and takes part in the transmission of impulses to the muscles.
If necessary, radical treatment methods are prescribed, in particular surgical removal of the thymus gland or its tumor. In some cases, radiation exposure is indicated. With proper treatment, most patients note a noticeable improvement in their general condition. However, periodic maintenance therapy is necessary throughout the patient's life.
The question of how to relieve muscle fatigue is also relevant for people who have fatigue and pain in limbs- This is a consequence of the influence of other factors. If constant pain and a feeling of fatigue are associated with general fatigue, it is necessary to reconsider your lifestyle, ensure regular good rest, and reduce stress. Often, rapid and very severe pain and fatigue in the muscles appears after training. It is important to take a responsible approach to the selection of exercises, taking into account the general condition of the body and the presence of chronic diseases. However, a person must constantly practice adequate physical activity.
It is important to balance your diet and constantly maintain the correct drinking regime to prevent dehydration. If necessary, you should take care of changing your shoes to more comfortable ones. Massage and a warm, relaxing bath help to effectively relieve fatigue.
If muscle weakness is associated with other diseases, you should definitely tell your doctor about this symptom, who will adjust the treatment regimen. Particular attention should be paid to the health of those who have weakness of the heart muscle, since if not properly treated, this condition can be life-threatening.
Why does weakness occur in the arms and legs? The reasons for this condition will be discussed in this article. We will also tell you about how to treat this pathology and which specialist to contact.
General information
Quite a large number of people periodically experience weakness in the muscles of their arms and legs. The reasons for this phenomenon should only be identified by an experienced specialist. After all, unexpected and growing weakness in the limbs, when the legs are “filled with lead” and the hands are not able to hold even a cup of coffee, may indicate the development of a serious illness.
Most often, the condition in question is transient and disappears very quickly. But is it possible to neglect this pathological phenomenon? Doctors say that if you develop severe or even transient weakness in the limbs, you should definitely undergo a medical examination.
Weakness in the arms and legs, dizziness: main causes
What could cause the condition in question? In most cases, this phenomenon is a sign of a neurological disorder, which is accompanied by a violation of neuromuscular impulses.
Why else might weakness in the arms and legs occur? The causes of this condition are often associated with electrolyte imbalance or metabolism. As a rule, this phenomenon is observed when following strict diets or violating the drinking regime (for example, when there is a lack of fluid in the human body).
In addition, the development of weakness in the limbs can occur due to impaired functioning of the kidneys, liver and other organs of the digestive system.
Other reasons
Why does weakness develop in the arms and legs? The causes of this condition are associated with the presence of:
- cervical spondylosis;
- cervical osteochondrosis;
- inflammatory or traumatic lesions of the shoulder, scapular or wrist areas;
- shoulder arthritis.
Most common reasons
Severe weakness in the arms and legs, the causes of which were described above, causes great discomfort to the patient. After all, such a state can take a person by surprise (for example, on the street, while driving a vehicle, at work, and so on). Therefore, it is imperative to identify the cause of this phenomenon.
Above we told you about why weakness in the arms and legs may occur. The reasons we have listed are far from the only ones. According to experts, this condition can also occur in the presence of diseases and conditions such as:
- lumbar osteochondrosis;
- lumbar hernia in the spine;
- lumbago;
- menstruation, pregnancy:
- menopause;
- hormonal changes (for example, during puberty and before menstruation);
- endocrine diseases (pathologies of the thyroid gland, diabetes);
- experiences, nervous stress, chronic fatigue syndrome.
It should also be said that there can be many reasons for the development of weakness in the limbs. Therefore, it is extremely important to diagnose all possible pathologies.
Muscle weakness
Muscle weakness in the arms and legs, the causes of which should only be diagnosed by a doctor, is treated in different ways. But before starting therapy, you need to make sure whether this symptom is the only one, or whether it is accompanied by some pain, sensory disturbances, numbness, and so on. For example, arthritis, in which there is obvious weakness in the limbs, is almost always characterized by discomfort in the joints, but dermatomyositis is often accompanied by skin lesions.
True weakness in the muscles of the legs and arms usually occurs symmetrically. Moreover, it is completely independent of physical activity. As a rule, this condition is observed first in the lower extremities, and then gradually moves to the arms.
Muscle weakness: what is it associated with?
What causes muscle weakness in the arms and legs? The reasons for this unpleasant phenomenon may be hidden in the development of many diseases. However, most often this condition indicates pathologies such as:
- diabetes;
- protein deficiency in the body;
- electrolyte metabolism disorder;
- anemia or hypovitaminosis;
- an inflammatory process occurring in any organ;
- dehydration of the body;
- presence of rheumatoid arthritis;
- penetration of infection into the body;
- neurological pathologies;
- exposure to toxic substances or poisoning;
- misuse of certain medications;
- diseases of the thyroid gland with metabolic disorders;
- emotional overload and stressful situations experienced.
Weakness in the left arm and leg: causes of development
As a rule, when weakness develops in the left arm and leg, experts talk about a stroke, that is, an acute cerebrovascular accident. Indeed, a clear sign of such a pathology is precisely the numbness of one half of the body (most often the left). Such cases occur quite often. However, it should be noted that this is far from the only ailment that is expressed in the impotence of the limbs. So why else might weakness in the arms and legs occur? A similar condition is often hidden in:
- cardiopathologies (that is, diseases of the coronary vessels and heart);
- vegetative-vascular dystonia, obliterating endarteritis;
- diseases of the left kidney, including the development of a tumor process in this organ;
- diseases of the spleen;
- thromboangiitis;
- diseases of the spine, including its curvature, hernia and tumor process.
It must also be said that it is impossible to diagnose all of these diseases without special research methods. Therefore, if weakness in the limbs occurs, you should contact a doctor, who is obliged to refer the patient for further examination in order to identify the exact cause of the pathology in question. As for a stroke, if you suspect it, you should urgently visit a specialist.
Weakness in the limbs accompanied by trembling
Frequent tremors of the legs or arms are called trembling. Very often this condition is accompanied by weakness. It is quite difficult to identify the cause of this phenomenon. At the same time, experts argue that such a condition can be essential, physiological, cerebellar and parkinsonian.
Essential tremors and weakness of muscle tissue can be hereditary, and are also often associated with the patient’s age. This condition intensifies with physical activity. At the same time, it is not dangerous, but it significantly affects a person’s quality of life.
Physiological tremors and weakness in the limbs are the most common condition. As a rule, it is associated with anxiety, nervous overexcitation, fear, hypothermia, fatigue, certain diseases of the nervous system and endocrine system, as well as withdrawal syndrome. It should also be said that such tremors often appear after long exposure to the sun or taking large doses of caffeine.
Weakness and cerebellar tremors develop with Thus, this may be a sign of congenital cerebellar ataxia, multiple sclerosis, and so on.
Parkinsonian tremors and weakness indicate the presence of Parkinson's disease.
Weakness in the limbs accompanied by numbness
A condition in which there is weakness in the limbs, as well as numbness, may indicate an impending cold or other infectious disease. Also, a similar phenomenon is often observed with poor sleep, insufficient nutrition and overwork.
If the limbs gradually become numb and weakness appears in them (for example, over the course of a week, a month, or even a year), then we can talk about damage to the spinal cord, brain, or In such cases, a medical examination is necessary.
It must also be said that the symptoms in question very often indicate diseases of the musculoskeletal system, including intervertebral discs, spinal column, bones and joints. A similar condition can also occur after a back injury.
Who to contact and how to treat?
Now you know why weakness occurs in the legs and arms. The causes and treatment of this pathology are discussed in this article.
If weakness in the limbs suddenly develops, the patient needs to lie down and ensure maximum peace and relaxation. You can also sit quietly for about 20 minutes.
In some cases, the normal state can be restored by taking some sedative drug (for example, Novopassit, valerian extract, Fitosed, and so on).
If you have weakness in your limbs, you should never drink alcohol or smoke. In this case, it is better to brew a soothing tea or make an infusion with mint, chamomile, honey or linden.
If the cause of this condition is a serious illness, then you should consult a doctor. Subspecialists such as a neurologist, traumatologist, psychologist and endocrinologist will help you understand the situation.
