What could cause the sensation of something blocking during a bowel movement?

Reviewed by Yoshinori Abe, MD

Internal Medicine

A sensation of blockage during a bowel movement is often caused by one of three main issues: fecal impaction (when hard, dry stool becomes stuck in the rectum), an intestinal obstruction such as a small bowel obstruction that prevents normal passage, or external pressure from a pelvic mass pressing on the bowel. Each cause has distinct symptoms and treatments, so identifying the underlying issue is essential.

Because these conditions range from easily treatable to medically urgent, it's important not to guess. Taking a free, instant, online symptom check can help you clarify your symptoms, understand possible causes, and decide whether home care, a doctor's visit, or urgent care is the right next step.

Explanation

Sometimes, people feel like something is stuck when they go to the bathroom. One common reason is fecal impaction. This happens when hard stool builds up in the bowel, making it tough for softer stool to pass through. Fecal impaction can occur if someone isn't drinking enough water, eating too many low-fiber foods, or not moving around enough.

Another reason might be a partial bowel obstruction. This is a blockage in a part of the small intestine that can limit the normal flow of things inside. Sometimes, a mass or growth in the pelvic area can press against the intestines, giving a similar feeling. Each of these issues puts pressure on the bowel and makes it feel like there is a blockage when trying to have a bowel movement.
