The pain in the stomach does not hurt after the stool, and is related to constipation, chronic enteritis and intestinal dysfunction, as follows: 1. Constipation is caused by excessive absorption of water in the stool by the intestines, and the nature of the stool is too dry. Constipation is caused by irritation of the intestines during defecation, so patients will have mild pain, and after the feces is discharged, the intestinal facilitation will gradually weaken, and the pain will gradually decrease. 2. Patients with chronic enteritis will have edema and congestion of the intestinal mucosa, and the function of the intestinal system will be affected, and some substances in the feces will cause pain due to irritation of the intestinal mucosa during defecation. The pain will naturally subside after the bowel mucosa is not stimulated by feces.3. Patients with intestinal dysfunction will have stress reactions, some of which are caused by food stimulation of the intestines, and the painful symptoms of the intestines will naturally subside when the irritating substances are discharged.
