How is muscle atrophy caused

summary

Muscle atrophy refers to rhabdomyodystrophy, muscle fiber thinning, or even disappear, resulting in muscle volume reduction. Literally, this disease is very harmful. But what is the cause of this disease?

How is muscle atrophy caused

Reason 1: myogenic atrophy is common in muscular dystrophy, dystrophic myotonia, periodic paralysis, polymyositis, trauma such as crush syndrome, ischemic myopathy, metabolic myopathy, endocrine myopathy, drug-induced myopathy, neuromuscular dystrophy, such as myasthenia gravis.

The second reason: the motor neuron lesion of disuse muscular atrophy is caused by long-term immobility of muscles and systemic wasting diseases, such as hyperthyroidism, malignant tumor, autoimmune diseases, etc.

Reason 3: neurogenic muscular atrophy is mainly caused by spinal cord and lower motor neuron lesions. It can be seen in vertebral bone hyperplasia, intervertebral disc disease, spinal nerve tumor, arachnoiditis, neuritis, plexus disease, spinal nerve tumor, arachnoiditis, neuritis, plexus disease, nerve injury, syringomyelia, motor neuron disease, Guillain Barre syndrome, brain disease and spinal cord disease, resulting in disuse muscular atrophy, etc.
