Constipation refers to the state of not having a smooth bowel movement, including the two cases of not passing feces smoothly and not passing feces even if they are not dry. Generally less than 2-3 times a week can be called constipation. Normal people’s bowel habits vary greatly, which is related to individual differences, living habits, especially eating habits. In general, normal people have 1-2 bowel movements per day, some have 1 bowel movement in 2-3 days, but most people have one bowel movement per day. Constipation is one of the common conditions of the digestive system. In the past, people do not pay attention to, in many medical books, only as a visceral symptoms to be introduced, and in the treatment, can only be limited to “headache, foot”, so the effect is not good. With the development of basic medical research and diagnosis and treatment technology, the medical concept and diagnosis level of constipation has undergone a major breakthrough. At present, we clearly recognize that a small number of patients with constipation is caused by intestinal and systemic diseases, belonging to organic constipation, the majority of patients with constipation belong to simple constipation, due to defecation reflex malfunction or obstruction caused by rectal constipation and colon constipation caused by slow peristalsis of the colon. In recent years, functional constipation has progressed rapidly, greatly contributing to the development of constipation therapy and improved efficacy.
