About muscle atrophy. What causes muscle wasting?

Common causes of neurogenic muscular atrophy are disuse, dystrophy, ischemia, and toxicity. Anterior horn lesions, nerve roots, plexus, peripheral nerve lesions, etc. can cause conduction disorders of nerve excitatory impulses, so that some muscle fibers are disused, resulting in disuse amyotrophy. On the other hand, after any part of the motor neuron is damaged, the release of acetylcholine from its terminal part decreases, and the sympathetic nerve nutrition is weakened, resulting in muscle atrophy.

It is recommended that you go to the hospital as soon as possible**, and timely** is the key to the patient's recovery.

Exercise more. You can add an appropriate amount of telecontrol with weight. Remember to relax your muscles when you're done. It's best not to sit too often. Insist on 1-3 hours of distance every day. If it doesn't work, it will also be examined at the regional hospital.

Muscle atrophy is diverse, and can be caused by a variety of primary diseases and trauma. There are mainly the following reasons:

1. Genetic factors.

For example, Duchenne muscular dystrophy, also known as pseudohypertrophic muscular dystrophy, is a genetic disorder. Patients with this type of disease develop in adolescence and have difficulty rolling over, sitting up, and standing up. The disease is rare, there is no way to do it, and muscle atrophy will gradually worsen until death.

2. Neuropathy.

It mainly refers to neurogenic amyotrophic atrophy, such as amyotrophic lateral sclerosis, cerebral infarction, poliomyelitis, etc. Nerve lesions can cause nerve signaling disorders, which can lead to the disuse of some muscle fibers, the reduction of motor capacity, and the disuse of muscle atrophy.

In addition, when neurons are damaged, the release of acetylcholine from their terminals decreases, and neurotrophic effects are weakened, resulting in muscle atrophy.

3. Trauma. When a fracture occurs, it may cause muscle atrophy in the affected area. On the one hand, during the fracture**, due to the long-term fixation of the affected limb and other reasons, the limb activity is reduced, and disuse muscle atrophy occurs. On the other hand, a fracture may damage the surrounding nerves or cause compression of the spinal cord or nerves, and muscle atrophy may occur in the innervated area.

4. Other diseases.

For example, cervical spondylosis, lumbar disc herniation, tumors, etc. can cause compression of the spinal cord and nerves in the corresponding parts, which may cause muscle atrophy; In addition, malnutrition, Cushing's syndrome, hyperthyroidism, etc. can also lead to muscle atrophy;

There are also inflammatory diseases such as myositis, arthritis, and slow staining that can also cause muscle wasting.

Myogenic amyotrophy is commonly seen in muscular dystrophy, dystrophic myotia, periodic paralysis, polymyositis, trauma such as crush syndrome, ischemic myopathy, metabolic myopathy, endocrine myopathy, drug-induced myopathy, neuromuscular transmission disorder myopathy, such as myasthenia gravis, etc.

Disuse amyotrophic upper motor neuron disease is caused by long-term inactivity of muscles, systemic wasting diseases, such as hyperthyroidism, malignant tumors, autoimmune diseases, etc.

Neurogenic amyotrophy is mainly caused by lesions of the spinal cord and lower motor neurons. It is seen in vertebral hyperostosis, intervertebral disc lesions, spinal nerve tumors, arachnoiditis, neuritis, plexopathy, spinal nerve tumors, arachnoiditis, neuritis, plexopathy, nerve injury, syringomyelia, motor neuron disease, Guillain-Barré syndrome, brain lesions, spinal cord lesions, and disuse muscular dystrophy.

I used to have thighs and back muscle atrophy due to cold and dampness, which affected blood circulation, and the muscles did not get normal nutrition and atrophy.
