Constipation is a common symptom. It is because the fecal stay in the intestine for too long, the water content is absorbed, the feces are hard and hard to be discharged, and the normal frequency of defecation disappears, which is called constipation. After the food is digested and absorbed in the gastrointestinal tract, the remaining residue is feces, which is smoothly discharged from the colon in 24 to 48 hours. It is the basic physiological process of the body. If stool is retained in the body, the defecation time exceeds 48 hours is often regarded as Constipation; but there are also healthy people who have different bowel habits. There are bowel movements every 2-3 days, which may not always be constipation. But if it is too inconvenient for a long time, it will produce various symptoms of poisoning. In severe cases, it will lead to electrolyte and acid-base balance disorders, causing various diseases, for which people need to pay attention. The normal bowel movement process is completed by the two steps of colon movement and bowel reflex. Any factor that affects these two links can cause constipation. Constipation is divided into obstructive constipation, spastic constipation and flaccid constipation.

　　Obstructive constipation is caused by intestinal adhesions, tumors, or fecal lumps that block the intestine. Therefore, the primary disease should be treated first to remove the cause and the constipation will be relieved naturally. Spastic constipation is caused by hyperactive sympathetic nerve function in the intestinal wall due to drugs, condiments, excessive smoking or excessive drinking of tea, coffee, and alcohol, causing spasm of the intestinal wall and excessive contraction of muscle tension, resulting in narrowing of the intestinal cavity and difficulty in passing stool. Flaccid constipation is caused by too little intake and excessive seizure, lack of dietary fiber to stimulate colonic movement, and can not produce constipation, and elderly, obese, pregnant women, etc. affect the bowel movement due to muscle weakness to help defecation.

　　 1. Energy supply issues

　　 For obstructive constipation, the diet should be limited to providing only part of the energy and keep the amount of food residue to a minimum, and parenteral nutrition as the The main way to supply energy. Those who are constipated due to intestinal muscle weakness due to old age and frailty can add some energy and choose carbohydrates and fat to provide energy to facilitate bowel movements.

　　 2. The provision of protein, lipids and carbohydrates should be targeted

　　People with obstructive constipation should eat as little as possible or prohibit eating before the cause of the obstruction is relieved Mainly supply nutrients outside the gastrointestinal tract. Other types of constipation protein are generally supplied, and the elderly and frail constipation can increase protein in moderation.

　　People with spastic constipation and flaccid constipation can properly increase fat intake. Fat has a role in intestinal function. Fatty acids can promote bowel movements and facilitate bowel movements, but it should not be too much.

　　Convulsive constipation should eat low-slag semi-liquid diet first, and then change to low-slag soft food. Those with flaccid constipation should provide more crude fiber-containing food to stimulate the intestine, promote gastrointestinal peristalsis, and enhance the ability of defecation, such as coarse grains, peeled fruits and various fresh vegetables.

　　People with spastic constipation and flaccid constipation need to drink plenty of water and beverages to keep the intestinal tract hydrated enough to facilitate fecal discharge.

　　3. Foods that are beneficial for the prevention and treatment of constipation

　　We should choose fresh vegetables with thinner fibers and less cellulose according to different types of constipation, such as spastic constipation, and those with flaccid constipation Fresh vegetables and fruits containing crude fiber should be selected, such as various coarse grains, water spinach, soybean sprouts, bran, etc. Banana, walnut meat, pine nuts, black sesame, honey, etc. are all available.
