Toxic disorders

  1. Botulism
  2. Organophosphate poisoning
  3. Paralysis due to tetrodotoxin poisoning

Neurological disorders

Cerebral palsy Cerebral palsy
is a disease that causes problems of balance and movement. It also causes the loss of muscle tone.
It can be genetic (infantile cerebral palsy) or occur after a head injury  or a disease.

Myasthenia gravis
Myasthenia gravis is a chronic autoimmune disease characterized by fatigue and intermittent muscle weakness.
If the brain fails to send signals for the contraction of the muscles, there is a loss of strength, which prevents movements.
The effects and symptoms of myasthenia gravis are:

  1. Fallen eyelids
  2. Difficulty swallowing
  3. Muscular fatigue
  4. Difficulty breathing (due to weakness of the muscles of the chest wall)
  5. Facial paralysis

Among the treatments are medications and surgical operation.

MS
The MS is a disease that affects the central nervous system (brain and spinal) and millions of nerve cells in the body.
The nerve fibers are protected by a fatty substance called myelin. In case of multiple sclerosis, inflammation of the myelin occurs.
Consequently, the myelin layer separates from the nerves and degrades.
If the nerve runs out of myelin, there is a delay in sending the impulses.

There are many possible symptoms, such as:

During the first phase, the patient with multiple sclerosis presents difficulty to run, but only in one leg, the right or the left.
In an advanced stage, the patient has to stop after a walk and it takes a long time to recover.

Anxiety and depression
These mental disorders can cause fatigue and weakness (especially in the legs), rapid heartbeat , tingling, etc.

Other neurological diseases

  1. Amyotrophic lateral sclerosis is a neurodegenerative disease in which the motor neurons die and the patient can not control the muscles.
  2. Guillain-Barré syndrome is an autoimmune disease that produces weakness in the muscles of the legs.
  3. Compression of the nerve.
  4. Bell’s palsy (affects the muscles of the eye).
  5. Myotonic dystrophy.
  6. Stroke .

 

Muscular type disorders

Dermatomyositis
Dermatomyositis is an inflammatory disease that produces chronic skin and muscle inflammation .
It is an autoimmune disease of the connective tissue that develops gradually. It produces muscle weakness, especially proximal (muscles of the thighs, back and arms to the elbow).
The symptoms of dermatomyositis are:

  1. Muscle pains
  2. Gastric and duodenal ulcers
  3. Intestinal perforation
  4. Pulmonary disorders
  5. Fever
  6. Fatigue
  7. Weightloss

It causes a  red or purple rash on the face, hands, knees, chest and back.
There is no treatment for this disease. However, cortisone  and immunosuppressant drugs reduce symptoms.

Myositis
Myositis is a disorder that produces inflammation in muscle fibers and is one of the causes of muscle weakness.
The weakness can also spread to other parts of the body, causing fatigue and pain.

Duchenne muscular
Muscular dystrophy is a genetic disease characterized by gradual muscle atrophy.
The symptoms of muscular dystrophy are:

  1. Weakness
  2. Loss of mobility
  3. Lack of coordination

There is no treatment for muscular dystrophy.

Other causes of muscular type

  1. Rhabdomyolysis is characterized by the death of muscle tissue.
  2. Polymyositis is a chronic inflammatory disease of the muscles.
  3. Myotonia is a disease characterized by the inability of the muscles to relax quickly after contracting.
  4. The fibromyalgia is a chronic disorder characterized by widespread muscle pain, fatigue (especially in the morning) and stiffness.
  5. Mitochondrial myopathies are diseases in which the organs that produce energy for the cells are affected.

Other reasons of muscle weakness

  1. Malignant tumor, such as multiple myeloma (affects mostly the elderly).
  2. Restless legs syndrome.
  3. Anemia.
  4. Malnutrition
  5. Hodgkin’s disease .
  6. West Nile virus.
  7. Low pressure .

 

How does it manifest? Symptoms of muscle weakness

One of the most frequent symptoms of muscle fatigue is the loss of strength.

Although the symptoms in women and men are similar, women may be more affected by this disorder during:

Pregnant women develop these symptoms, especially in the legs and arms.
The muscle weakness in women is due mainly to:

Here is a list of signs and symptoms that are manifested together with muscle weakness

  1. Fatigue
  2. Muscular atrophy
  3. Inability to hold the arm
  4. Difficulty grasping objects due to hand weakness (for example, carpal tunnel syndrome )
  5. Fallen knee (loss of muscle function)
  6. Inability to perform a physical activity
  7. Drowsiness
  8. Prolonged tiredness
  9. Discomfort
  10. Insomnia
  11. Headache

It can produce involuntary and rapid muscle contractions called myoclonic spasms or fasciculations .
These momentary muscle contractions occur mostly in people with amyotrophic lateral sclerosis.

Symptoms are also tremors, which may be due to the maximum contraction of the muscle.

Muscle weakness after surgery
Patients who have undergone surgery soon lose quadriceps and calf strength.
If they try to do some simple exercises, these patients perceive that the leg begins to tremble when performing a maximum contraction.

 

Diagnosis of muscle weakness

The diagnosis of muscle weakness is made through an evaluation by the doctor and the following tests:

  1. Blood test
  2. Electromyography
  3. Magnetic resonance
  4. TAC

 

Treatments and natural remedies for muscle weakness

The following natural remedies can help in the treatment of muscle weakness as long as it is not caused by a serious illness.

Physical
activity Regular physical activity increases endurance, appetite and reduces stress.
The exercises play a fundamental role to promote health and fight against diseases such as fibromyalgia, such as:

  1. Aerobic exercises
  2. Stretching
  3. Yoga

Rest
Excessive effort can produce muscle weakness.
Therefore, after that, you have to rest properly.
It is necessary to sleep at least 7 hours a day.

Drink plenty of water
Drinking a sufficient amount of water prevents  dehydration  and promotes digestion.

Healthy
diet A balanced diet plays an important role in reducing muscle weakness.
It is best to avoid fried and high-fat foods.
It is advisable to eat fruit, vegetables (rich in vitamins), cereals, nuts and seeds because they help to stay healthy and fit.
As far as possible, supplements should be avoided, since mineral salts and vitamins are found in food.
