How Does IBS Contribute to Incomplete Bowel Movements?

In people with IBS, especially those with constipation (IBS-C), the muscles in the intestines may not contract or relax in the normal rhythm. Instead, they sometimes move too slowly, which means the stool stays in the colon for a longer time. This delayed movement can lead to extra water being absorbed from the stool, making it hard and dry. When you try to have a bowel movement, the stool may not be fully passed out of the colon, which causes a feeling of incomplete emptying. Moreover, the nerves in the gut can be extra sensitive in IBS. They send signals that might make you feel like you still need to go even after you’ve used the bathroom. Stress, diet, and changes in gut bacteria also play a role in worsening these symptoms. Managing IBS often means finding ways to adjust your eating habits and sometimes using medication to help the muscles move better, which can help reduce the feeling of not fully emptying your bowels.
