Can endometriosis cause a bowel obstruction?

Yes—endometriosis can cause a bowel obstruction, but it’s uncommon. When endometriosis involves the bowel (most often the rectum or sigmoid colon), deep disease and scarring can narrow the bowel (stenosis) or tether it in ways that interfere with normal passage of stool and gas. In these cases, symptoms may look “GI” rather than gynecologic, and a colonoscopy can still appear normal because endometriosis often affects the outer bowel wall or deeper layers instead of the inner lining.

More often, bowel endometriosis causes chronic or cyclical symptoms like painful bowel movements, constipation/diarrhea shifts, bloating, cramping, nausea, or rectal bleeding that tracks with your cycle. If your symptoms suggest significant narrowing—or you’ve had episodes of severe distension, vomiting, or inability to pass stool/gas—our team focuses on careful pre-op mapping and surgical planning so the right expertise is in the room. If you’re dealing with bowel symptoms alongside pelvic pain, we encourage you to explore our bowel endometriosis information and reach out to schedule a consultation so we can evaluate the full picture and discuss next steps.
