What is the reason for the granular stool?

The most common cause of granular stool is constipation. After constipation occurs, the intestinal motility becomes very slow, and the stool stays in the intestine for a longer time. The water in the stool will be absorbed by the intestine, so it becomes particularly dry and eventually forms granules. It should also be considered as a result of irritable bowel syndrome. This disease will affect digestion and absorption of the intestine, resulting in slow intestinal motility and making the stool appear granular.
