Deep Disease
Can endometriosis cause a bowel obstruction?
The short answer
Yes, endometriosis can cause a bowel obstruction, but it’s uncommon. Deep disease and scarring can narrow the bowel or tether it in ways that interfere with stool and gas passing, and a colonoscopy can still appear normal.
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, causing stenosis, or tether it in ways that interfere with the normal passage of stool and gas. In these cases, symptoms may seem gastrointestinal rather than gynecologic, and a colonoscopy can still appear normal because endometriosis often affects the outer bowel wall or deeper layers rather than the inner lining.
More often, bowel endometriosis causes chronic or cyclical symptoms like painful bowel movements, shifts between constipation and diarrhea, 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 or 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.

Don’t ignore bowel warning signs.
Deep endometriosis can rarely narrow or tether the bowel and cause obstruction-like symptoms—even when a colonoscopy looks normal. Our specialists can evaluate bowel-involving endometriosis and help plan the right imaging and treatment options.
Questions people ask next
All deep disease questionsCan constipation be a sign of bowel endometriosis?
Yes, constipation can be a sign of bowel endometriosis, especially when it predictably flares before or during your period. It can result from effects on the bowel, adhesions or pelvic floor muscle spasm, but symptoms don’t reliably show how deep endometriosis is.
What are the symptoms of bowel endometriosis?
Bowel endometriosis can cause lower abdominal or pelvic pain, bloating, constipation and/or diarrhea, nausea, and pain with bowel movements. Symptoms may fluctuate with your menstrual cycle, and some people notice rectal bleeding, especially around menstruation.
Do bowel endometriosis symptoms require a colonoscopy?
Bowel endometriosis symptoms do not usually require a colonoscopy. Most disease is outside the bowel or within its wall, so colonoscopy cannot reliably confirm or rule it out. It can be part of the workup for another condition or red-flag bowel symptoms.
Can a CT scan detect bowel endometriosis?
Sometimes, but a CT scan is not reliable for diagnosing or ruling out bowel endometriosis. Many lesions won’t be visible, so evaluation typically relies more on symptoms, a targeted pelvic exam, and expertly interpreted ultrasound and/or MRI.
