What is the cause of muscle wasting?

1. Muscle atrophy is generally due to no exercise or little exercise, resulting in little muscle contraction, and muscle function degeneration; For example, if you are in bed after an injury, your muscles are resting for a long time, and you don't have an appropriate amount of contraction exercises. In addition, nerve damage causes muscles to contract. Because of malnutrition, myotissue protein is decomposed, causing atrophy, generally due to insufficient nutrient intake or imbalance of nutritional structure leads to insufficient protein in the body, causing atrophy.

2. Muscular dystrophy disease belongs to myopathy and motor neuron disease, which is a type of disease that is difficult to treat in the world, and these diseases often cause patients to lose their ability to live and even die due to muscle weakness and muscle atrophy. Muscular dystrophy diseases include many diseases, among which the common ones are myasthenia gravis, progressive muscular dystrophy, amyotrophic lateral sclerosis, progressive spinal muscular atrophy, syringomyelia, polyradiculitis, peripheral neuritis, and neuromuscular atrophy caused by various causes. Muscular dystrophy is a type of myopathy and motor neuron disease, which is a type of disease that is difficult to treat in the world, and these diseases often cause patients to lose their ability to live due to muscle weakness and muscle atrophy.

The pathogenesis of amyotrophic diseases can be divided into three types: neurogenic amyotrophia, myogenic amyotrophia, and disuse amyotrophia.

Amyotrophy refers to the visible atrophy of the overall volume of muscles due to various reasons, which is caused by the decrease in the number or volume of muscle fibers, therefore, muscular dystrophy is not a disease, but a clinical symptom. Neurogenic amyotrophic disease mainly refers to the amyotrophy caused by lower motor neuron damage caused by various reasons, and lower motor neuron disease mainly refers to the damage of lower motor neurons such as anterior horn cells and peripheral nerves of the spinal cord, especially the muscle atrophy caused by anterior horn cell damage usually progresses rapidly, such as polio, amyotrophic lateral sclerosis, etc.

Myogenic amyotrophy refers to muscular atrophy caused by a lesion of skeletal muscle itself, such as progressive muscular dystrophy associated with abnormal genes. Disuse amyotrophy refers to amyotrophy caused by limb paralysis, long-term bed rest, and reduced exercise caused by various reasons, and mostly involves disused limbs. Different ** amyotrophic atrophy has different clinical manifestations, signs, auxiliary examination results, ** mode and prognosis.

There are several causes of muscle atrophy, first of all, it is caused by muscle diseases, myositis such as polymyositis, and patients will have muscle atrophy and muscle damage. Secondly, patients with myasthenia gravis, there is a type of myasthenia gravis that is amyotrophic type, and patients can also develop muscle atrophy. There are also diseases of the peripheral nerves, such as diabetes, and the situation caused by metabolic factors after poisoning, or autoimmune factors, resulting in more serious muscle atrophy, which is caused by neurological factors caused by peripheral neuropathy.

Central nervous systems, such as spinal cord lesions, can also cause muscle wasting.

There are several causes of muscle atrophy: 1. Nerve diseases, peripheral nerve diseases can cause muscle atrophy such as Guillain-Barré syndrome, multiple peripheral neuropathy, when the peripheral nerve is damaged, the area it innervates loses neuronutrition, neurogenic muscular atrophy will occur, electromyography can be confirmed. 2. Muscle diseases are more common in polymyositis, dermatomyositis or various types of muscular dystrophy, the former is mainly an inflammatory lesion of the muscle, there is no muscle atrophy in the acute stage, if it is not timely, it lasts for a long time, and muscle atrophy can occur in the later stage.

Some patients with muscular dystrophy will have pseudohypertrophy, others will have significant muscle atrophy, and electromyography will show myogenic damage. 3. Disuse muscle atrophy, which is caused by the patient's brain or spinal cord damage resulting in limb paralysis, limb inactivity for a long time, muscle contraction movement, because of the gradual loss of exercise ability resulting in disuse atrophy.

The causes of muscle atrophy mainly include neurogenic and myogenic muscles, disuse and other reasons. Common diseases include poliomyelitis, amyotrophic lateral sclerosis, cervical spondylosis or Guillain-Barré syndrome, cerebrovascular disease, progressive muscular dystrophy, myositis, etc. Therefore, in the case of muscle atrophy, the specific cause can only be determined by combining the patient's medical history, electromyography and imaging examination.

After the determination of **, it is necessary to carry out ** in time, and at the same time, it is necessary to actively carry out ** exercise to improve the symptoms of local muscle atrophy.

Most of the cerebellar atrophy is considered to be a degenerative disease, there is no specific method, oral oxiracetam, piracetam, citicoline can improve brain metabolism**, you can apply some drugs to improve blood circulation, such as safflower, notoginseng, etc., may delay the progression of the disease. Patients may also experience cerebellar atrophy when drinking heavily over a long period of time. It is necessary to abstain from alcohol first, and at the same time can give the above drugs**, and if necessary, **** and balance training.

When cerebellar atrophy, patients mainly present with balance dysfunction, dizziness, nausea, and so on.

Muscle wasting can be one of the symptoms of several diseases or conditions. Here are some common diseases and conditions that can lead to muscle wasting:

1.Neuromuscular dystrophy (amyotrophic lateral sclerosis): This is a progressive neurological disorder that causes muscles to gradually atrophy and lose strength.

2.Spinal muscular atrophy: This is a genetic disorder that affects the cells in the anterior horn of the spinal cord, causing muscle loss and atrophy.

3.Multiple sclerosis: This is an autoimmune disease that causes damage to the central nervous system, which can lead to muscle wasting and limited motor function.

4.Myasthenia gravis: This is a disorder in which the muscles of the hail are impaired due to abnormalities in the immune system, and are characterized by muscle fatigue and fatigue.

5.Arthritic myositis and fibromyalgia: These are a group of chronic inflammatory diseases that can cause muscle discomfort, pain, and atrophy.

6.Myasthenic syndromes: This is a group of diseases in which muscle weakness and atrophy are caused by various causes, such as metabolic disorders, nerve damage, etc.

In addition to the above-mentioned diseases, other factors such as traumatic injury, long-term bed rest, muscle inactivity, malnutrition, cancer, etc., can also cause muscle atrophy. Because muscle wasting can be associated with a variety of underlying conditions, it is best to consult a doctor for evaluation and diagnosis if you or someone else is experiencing muscle wasting, and to take appropriate measures.
