Why is muscle atrophy prone to occur after a stroke and paralysis? How to avoid stroke?

Paralysis is a common complication of stroke. It not only causes physical inconvenience, but also causes serious damage to mental health. Stroke patients are mostly concentrated in people over 65 years old.

Then why is there muscle atrophy after a stroke and paralysis?

1.Neuropathy

Neuropathy is mainly due to excessive compression and hypoxia of the nerves in the brain, and the functional activity of the nerves has been damaged to some extent. If not treated in time, this damage is irreversible. After the nerve lesions occur, the signal transduction function of the nerves is impaired and self-conscious control cannot be performed, which can lead to muscle cell apoptosis and muscle atrophy.

2.Malnutrition

After a stroke, there will also be a skewed mouth angle, which will have a certain impact on eating. Long-term consumption of liquid food will cause the human body to lack relevant nutrients, and the water content of the body's muscle tissue will also decrease, resulting in thinness and insufficient fat. To support the muscles can cause muscle atrophy and muscle weakness.

3. Lack of exercise and maintain a fixed posture for a long time

After a stroke, when one limb is paralyzed, it is easy to maintain a relatively fixed posture. The patient refused to engage in activities because of fear of pain. Because of the lack of exercise in the limbs, the ability of muscle contraction will also decrease to a certain extent, which will lead to a decline in muscle strength, and for the elderly, the metabolic rate is showing a gradual decline, and muscle atrophy and weakness are more likely to occur.

The foundation to avoid muscle atrophy is to avoid the occurrence of stroke, which can be improved from the following points:

①　Control blood pressure

Most people with stroke are associated with hypertension. Obviously controlling high blood pressure is also one of the important factors in controlling the occurrence of stroke. It is best to control your systolic blood pressure within 140 mm Hg, and diastolic blood pressure within 90 mm Hg. For the elderly, the range of blood pressure control can be appropriately expanded. Antihypertensive drugs should be taken on time, and the diet should be low-salt and low-fat.

②　Regular physical examination

The root cause of some hemorrhagic strokes is the malformation of a certain blood vessel in the brain, or the presence of aneurysms inside. When the size of the tumor continues to increase, it can compress the fragile malformed blood vessels and cause the rupture of the blood vessels. Therefore, when an unexplained headache occurs, you can go to the hospital for a head CT examination to determine whether there are vascular malformations, intracranial tumors and other diseases.

③　Avoid trauma

Part of hemorrhagic strokes are caused by trauma to the outside of the head, leading to intracranial hemorrhage. They are more common in injuries such as bruises, car accidents, and falls from high altitudes. In daily life, we must develop a sense of self-prevention and avoid engaging in dangerous sports and Work, if necessary, wear a safety helmet for prevention

④　Functional exercise

For people who have already been paralyzed, long-term physical training is required. Healthy limbs can be actively exercised. You can choose exercises such as finger climbing and slow walking. For paralyzed limbs, you can use the uninvolved hand. Massage, promote local blood massage, avoid further atrophy of muscle cells, you can also choose professional exercise equipment for exercise, for example, the hand function rehabilitation robotic gloves. It can effectively relieve hand edema, and reduce the muscular tension.

⑤　Strengthen nutrition

You can eat more foods rich in vitamins and protein. Sufficient protein can promote muscle production, and can also play a role in strengthening physical fitness. Eat more eggs, meat and other foods.
