Muscle weakness in the legs means loss of strength in the lower limbs.
Leg cramps or major muscle weakness can occur that do not allow standing for long periods of time.
This disorder is observed in adults and children.

Weakness and muscle aches
Weakness and muscle pain can occur together.
Causes of Muscle Pain
The pain causes a reduction in the force because the movement causes pain and, therefore, the affected person can not do daily activities or sports.
Causes of generalized muscle pain
Muscle pain is one of the main symptoms of musculoskeletal disorders such as:
- A fibromyalgia ,
- Diseases like influenza , colds or Lyme disease .
- Connective tissue disorders, for example systemic lupus erythematosus (SLE),
- Muscle degeneration, that is, polymyositis.
The pain that comes from one of these diseases can be mild or severe.
Causes of Localized Muscle Pain
The causes can be:
- A concussion ,
- An accident,
- Many exercises,
- Heavy work,
- Stretching or muscle strain ,
- A muscle contraction .
Peripheral neuropathy is another disease that causes muscle pain, in addition to tingling and loss of sensation.
The imbalance of electrolytes (eg sodium, potassium and magnesium ) in the blood causes weakness and muscle pain.
Loss of strength can have major consequences; for example, lumbar muscle weakness is a risk factor for herniated disc .
Causes of weak leg muscles
Muscle weakness in the legs can be caused by a variety of factors; some are harmless, while others can be dangerous.
Heavy physical activity is one of the most common causes of muscle weakness. Excessive exercise can cause fatigue and tiredness .
Athletes and athletes may have muscle weakness if they overdo it with difficult workouts.
It is essential to rest properly after a workout.
Diet and diet
One of the most frequent reasons for muscle weakness is diet.
Because of the very fast lifestyle, many people prefer fast food to healthy food.
Although fast food reduces hunger, it does not provide the necessary nutrients to the body.
All this can cause weakness in the legs and throughout the body.
Another cause for the weakness in the legs is poor circulation
The circulation problems in the legs can be caused by:
- An obstruction in the arteries,
- The rupture of the capillaries .
It can cause weakness, especially in muscles:
- From the shoulder,
- From the hip,
- Of the lower limbs,
- Of hand.
Side effects of medicines
Some medicines can cause muscle weakness, for example:
- A gentamicin,
- The corticosteroids (high dose)
- The diuretic (if they cause a decrease in the level of potassium in the blood)
- The laxatives.
Diseases that cause muscle weakness
A hormonal disorder called Addison’s disease causes a decrease in the production of aldosterone and cortisone (hormones from the adrenal gland). Among the consequences are:
Other metabolic diseases
2. Organic phosphate poisoning
3. Paralysis by tetrodotoxin poisoning
Cerebral palsy is a disease that causes problems of balance and movement; in addition, causes the loss of muscle tone.
It can be congenital (cerebral palsy) or secondary to a head trauma or a disease.
Myasthenia gravis is a chronic autoimmune disease characterized by fatigue and fluctuating muscle weakness.
If the brain can not send the signal to the contraction of the muscles, the force is lost and the movements can not be performed.
The signs and symptoms of myasthenia gravis are:
1. Drooping eyelids,
2. Difficulty in swallowing,
3. Muscle fatigue,
4. Difficulty in breathing (respiratory muscle weakness),
5. Inability to control facial expressions, etc.
Among the therapies there are medicines and surgery.
Multiple sclerosis (MS)
The MS is a disease that affects the central nervous system (brain and spinal cord) and millions of cells in the body.
Nerve fibers are protected by a lipid substance called myelin. In the case of multiple sclerosis myelin becomes inflamed.
The consequence is the separation of the myelin layer from the nerves and the destruction of this substance.
If the nerve remains without myelin, the impulses have a delay in conduction.
There are many possible symptoms, including:
- Difficulty walking,
- Loss of balance and coordination,
- Muscle weakness,
- Loss of strength,
- Rigidity ,
- Fatigue, tiredness and shortness of breath ,
- Incontinence ,
- Constipation ,
- Dizziness ,
- Pain in arms and legs.
The patient with multiple sclerosis in the first stage has difficulty running, but only with one leg, the right or the left.
At an advanced stage, the patient should stop after a walk and recovery times are very long.
Anxiety and depression
These mental disorders can cause fatigue and weakness, especially in the legs, rapid heart beat , tingling, etc.
Other Neurological Diseases:
1. Amyotrophic lateral sclerosis is a neurodegenerative disease in which the motor neurons are destroyed and the patient is unable to control the muscles.
2. Guillain-Barrè syndrome is an autoimmune disease that weakens the leg muscles.
3. Nerve compression.
4. Bell’s palsy (affects the eye muscles).
5. Myotonic dystrophy.
6. Stroke .
is an inflammatory disease that causes chronic inflammation of the skin and muscles.
This is a progressive autoimmune disease of the connective tissue that causes muscle weakness, especially proximal (muscles of the thighs, shoulders and arms to the elbow).
The symptoms of dermatomyositis are:
1. Muscle pain,
2. Gastric and duodenal ulcer ,
3. Intestinal perforation,
4. Pulmonary disorders,
5. Fever ,
6. Fatigue ,
It causes a red or purple rash on the face, hands, knees, chest and back.
There is no treatment for this disease, but it is possible to reduce symptoms with cortisone and immunosuppressants.
Myositis is a disease that causes inflammation of muscle fibers and is one of the causes of muscle weakness in the legs.
Weakness can radiate to other parts of the body causing pain and tiredness.
dystrophy Muscular dystrophy is a genetic disorder characterized by progressive muscular atrophy.
The symptoms of muscular dystrophy are:
2. Loss of mobility,
3. Lack of motor coordination.
There is no treatment for muscular dystrophy.
Other Causes of Muscle Type
1. Rhabdomyolysis is characterized by the destruction of muscles.
2. Polymyositis is a chronic inflammatory disease of the muscular apparatus.
3. Myotonia is a pathology characterized by slow relaxation of the muscles after a contraction.
4. Fibromyalgia is a chronic muscular disease characterized by generalized pain, fatigue (especially in the morning) and stiffness.
5. Mitochondrial myopathies are diseases in which the organs that produce energy for the cells are damaged.
Other causes of muscle weakness
How does this occur? Symptoms of muscle weakness
One of the most common symptoms of muscle fatigue is loss of strength.
Although the symptoms of muscle fatigue are similar in men and women, females are more prone for:
- The pregnancy,
- The menopause .
A pregnant woman develops these symptoms primarily on her legs and arms.
The muscle fatigue in women is caused mainly by:
- By fibromyalgia,
- For chronic fatigue syndrome .
2. Numbness of muscles,
3. Inability to support an arm,
4. Difficulty in grasping objects because of weakness in the hands (for example due to carpal tunnel syndrome ),
5. Knee instability,
6. Inability to perform physical activity,
7. Drowsiness ,
8. Prolonged fatigue,
11. Headache .
There may be involuntary and rapid muscle contractions called myoclonic spasms or fasciculations .
These momentary muscle contractions are mainly seen in people with amyotrophic lateral sclerosis (ALS).
Among the symptoms is also the tremor.
The tremor can be caused by the maximum possible contraction of the muscle.
Muscle weakness post-surgery
Patients who undergo surgery immediately lose strength in the quadriceps and calves.
If you try to do some simple exercises, you will realize that your leg is shaking because you are performing a maximum contraction.
Diagnosis of muscle weakness
Natural Treatment and Remedies for Muscle Weakness
The following natural treatments may help in the therapy of muscle weakness if it is not caused by serious diseases.
Regular physical activity improves endurance, appetite, and reduces stress .
Exercises have a key role in promoting health and fighting diseases such as fibromyalgia, for example:
Excessive exertion can cause muscle weakness. Therefore, after a tiring activity is advised a suitable rest.
You need to sleep at least seven hours a day.
Drink plenty of water
Drinking enough water prevents dehydration and helps digestion.
A balanced diet plays an important role in reducing muscle weakness.
It is best to avoid greasy and fried foods.
It is advised to eat fruits, vegetables (rich in vitamins), cereals, nuts and seeds because they are useful for staying healthy and fit.
If possible, it is best to avoid supplements because the minerals and vitamins are found in food.
