This situation may have the following points: 1, incomplete intestinal obstruction caused by functional dyspepsia, which is often the result of poor gastric power and is greatly related to poor digestive function caused by eating more. 2, occupying lesions in the intestine, if there is an occupying tumor in the intestine, resulting in narrowing of the intestinal lumen and causing stool discharge, which may lead to reduced discharge or no defecation. 3, inflammatory bowel disease and luminal narrowing, if there is ulcerative colitis or Crohn’s disease, as well as inflammatory infection stimulation leading to chronic inflammatory response, resulting in intestinal lumen edema, relative narrowing caused by poor stool discharge, this is relatively rare. If you have repeatedly eaten a lot of food without defecation, it is best to improve the abdominal plain film examination and, if necessary, colonoscopy to further exclude other possible causes.
