The yellow bean-like substance in the stool may be caused by indigestion, constipation, gastroenteritis and other reasons. 1. Indigestion: If the patient’s gastrointestinal digestive function is poor, the food can not be digested and absorbed, which leads to the phenomenon of yellow beans in the bowel movement. 2. Constipation: If the patient’s diet is not regular or drink less water, it will lead to fecal matter accumulating in the intestine for too long, causing constipation, which will also lead to the occurrence of the situation of yellow pea-like material in the stool. 3.
