Whether muscle atrophy leads to death depends on the location and degree of atrophy. If atrophy occurs in muscles located locally in the extremities, it does not usually lead directly to death. Each muscle in the body has a corresponding function, and if atrophy occurs in a muscle, it will lead to the loss of the corresponding function. If muscle atrophy occurs in the mouth and tongue, it can lead to hoarseness of speech, difficulty in swallowing, and choking and coughing; if muscle atrophy occurs in the extremities, it will show weakness of the limbs and limited movement; if the respiratory muscles have been involved, the corresponding respiratory function will be affected, and the inspiratory and expiratory functions will be limited, and the development of the disease can be serious enough to cause respiratory failure, leading to death. The causes of muscle atrophy include neurogenic and muscular origin, and clinical treatment should be directed at the causes and symptoms. When muscle atrophy occurs, the body’s immunity will be relatively low, limbs paralysis and weakness, if not treated in a timely manner to alleviate the disease progression, and eventually may be life-threatening. So when muscle atrophy occurs, you need to go to a regular hospital in time to identify the cause of the disease and treat it according to the disease.
