Why Might It Feel Like My Anus Is Blocked During a Bowel Movement?

Sometimes people feel that their anus is blocked when they try to have a bowel movement because stool has become very hard or packed in the lower part of the colon or rectum—this is called fecal impaction. When stool stays in the large intestine too long, it can dry out and become hard, causing a blockage-like feeling. Additionally, problems with the muscles and nerves around the anus, such as not relaxing well during a bowel movement (a condition sometimes called dyssynergia), can make it seem like the anus is blocked. Other issues, like inflammation or scar tissue from previous injury or surgery, may also contribute to this feeling. Doctors sometimes use special tests or studies to check the muscles and nerve function in the area. If you feel this way often, it is a good idea to talk with a doctor who can help find the cause and suggest ways to ease your symptoms.
