Recent pellet-shaped stools are associated with improper diet, constipation, irritable bowel syndrome, and need to be alerted to intestinal tumors. The formation of pellets in the stool indicates that the water in the stool is excessively absorbed. Some people have problems with their diet, such as eating too fine a diet, often eating protein and meat foods without dietary fiber. As the intestine is not stimulated by dietary fiber, peristalsis is relatively slow, and because the water in the stool is excessively absorbed in the intestine, it is expressed in the form of granules. In people with constipation, intestinal peristalsis is relatively slow and food residues stay in the intestine for a longer period of time, during which water is excessively absorbed. When irritable bowel syndrome patients have bad emotions, the disease will be triggered, some people have diarrhea and some people have constipation, so the stool is granular. For those who have pellet-like stools for a longer period of time, they should go to the hospital for colonoscopy in order to avoid intestinal tumors.
