The inability to pull the stool out one by one is caused by constipation, and some people are caused by polyps in the colon. Constipation is mainly caused by bad living and eating habits. People with constipation will have slow intestinal peristalsis, so the feces will remain in the intestinal system for a long time, especially when the colon remains for too long, the colon will repeatedly absorb the water in the feces. At this time, the feces will be too dry to form a grain-by-grain state, and it will also cause certain irritation to the intestines, which will cause difficulty in defecation.
When polyps appear in the colon, it will affect the peristalsis of the intestine, and it will be more difficult for feces to pass through the colon, so it will also form granular feces. Because polyps hinder defecation, they can't be pulled out. For patients with colon polyps, colonoscopy can be used for diagnosis and colon polyps can be removed in time.
