Constipation is mainly considered to be caused by slow gastrointestinal peristalsis, intestinal obstruction, etc., which can generally be relieved by eating more fiber-rich foods, such as bananas, leeks and so on. When the patient is constipated for a long time, the water of the intestinal contents is absorbed by the intestinal wall, causing the feces in the rectum and sigmoid colon to be drier, accelerating the formation of constipation, and at this time, appropriate consumption of foods containing a large amount of fiber and vitamins, such as bananas, leeks, etc., can promote gastrointestinal peristalsis and regulate gastrointestinal function. Through the promotion of gastrointestinal peristalsis, reduce the intestinal wall of the intestinal contents of the reserves of absorption, promote the discharge of stool, relieve constipation. If the above regulation does not improve the constipation, the patient must be consulted in the hospital to improve the examination, to clarify the cause of constipation, and the appropriate application of drugs for treatment, such as lactulose, glycerin enema, etc., but before using the drug, consult a physician, under the guidance of the physician to use the drug.
