The pain around the belly button before the stool, after the stool to get relief, may be a normal physiological phenomenon, but also may be associated with acute gastroenteritis, gastrointestinal dysfunction and other pathological factors. 1. Physiological phenomenon: the human body in the sense of defecation, the brain will send a signal to prompt the gastrointestinal peristalsis to speed up, and too fast gastrointestinal peristalsis may lead to gastrointestinal spasms, which produces the phenomenon of pain around the navel before the bowel movement. 2. Pathological factors: (1) Acute gastroenteritis: due to bacterial infection and inflammatory stimulation of the intestinal mucosa, it can cause smooth muscle spasm and contraction, resulting in pain, and the abdominal pain will be improved after discharging the stool. (2) Gastrointestinal dysfunction: when the patient ingests a large amount of food, which cannot be discharged in time, it will cause gastrointestinal dysfunction, which will cause the patient to have the symptom of pain around the umbilicus before the bowel movement, but will be relieved after the bowel movement. If the discomfort occurs for a long time, it is recommended to go to the hospital in time to get a clear diagnosis and active treatment under the guidance of professional physicians.
