Granular stool is a symptom of gastrointestinal dryness, constipation, and irritable bowel syndrome. Many people suffer from intestinal dryness and heat, and not only is the decomposition of food too advanced, but also the lack of water in the intestine makes it absorb a lot of water from the food residue when digesting food, and when the stool is discharged into the colon, the water is excessively absorbed and the stool becomes granular. Constipation is related to slow intestinal peristalsis and too fine a diet. After the formation of stool, it will accumulate in the sigmoid colon and rectum for a long time, so the nature of the stool will be too dry and the longer it accumulates, the more severe the dryness will be, and some people may also form fecal stones. When irritable bowel syndrome is constipated, it is characterized by slow bowel movements and dry stools, and the stools are granular.
