Paralysis is a disease in which the lower extremities of the body completely or partially lose motor function and the random movements are reduced or lost after the occurrence of random movement or loss of sensory disorders. Central paralysis of the lower extremities is caused by lesions in the cortical motor projection area and the upper motor neuron pathway, which can cause upper motor neuron paralysis. The common causes include cranial trauma, tumors, inflammation, cerebrovascular disease, degeneration, poisoning, and certain diseases of internal medicine, such as diabetes, hematoporphyria, macrocytic anemia, and vitamin B12 deficiency. Patients with central paralysis of the lower limbs should have a light diet, with more fresh vegetables, fruits, soy products, as well as kelp, jellyfish, shrimp and shrimp, and appropriate intake of fish, chicken, eggs and milk and dairy products to ensure adequate protein intake. Those with hypertension should control their salt intake, generally 5 grams per day is appropriate. Those who have difficulty in eating should be fed or nasally fed. Before nasal feeding, gastric juice should be pumped to the stomach before infusing food to prevent food from accidentally entering the trachea. After each food infusion, a small amount of warm water should be infused to clean the lumen of the tube, and then the nasal feeding tube should be clamped. Long-term nasal feeders should change the gastric tube once a week. Clean the nose and mouth in a timely manner. 1, should supply nutritious and easily digestible food, must meet the supply of protein, inorganic salt and total caloric energy. Patients with paralysis often have the psychology of drinking as little water as possible for fear of urinating too much, which is not good for the patient. 3, pay attention to dietary fiber, increase gastrointestinal motility, food should not be too fine, in order to prevent constipation. 4, avoid strong tea, alcohol, coffee and spicy stimulating food. 5, according to the cause of paralysis, adjust the diet taboos. For example, stroke patients should control salt and cholesterol intake and increase food rich in B vitamins.
