What might cause incomplete bowel movements without the presence of diarrhea?

When someone feels as if they haven't completely emptied their bowels, it is often a sign of constipation rather than diarrhea. For example, studies have shown that people with diabetes may have constipation that comes with hard stools and a sense that evacuation is incomplete. This might be because diabetes can affect the nerves and muscles in the digestive system, making it difficult for the colon to move stool smoothly.

Additionally, conditions like slow transit constipation or problems with pelvic floor muscles can make it tougher to push out all the stool. When these muscles or nerves do not work well, stool may not move completely out of the rectum, which creates the feeling of incomplete bowel movements.

Other factors that may contribute include not eating enough fiber, not drinking enough fluids, or a lack of physical activity.
