Can adenomyosis cause diarrhea?

Yes—adenomyosis can be associated with diarrhea for some patients, especially around the menstrual cycle. Even though adenomyosis stays within the uterine muscle (it doesn’t spread onto the bowel), the inflammation, cramping, and pelvic nerve cross-talk it creates can “spill over” and trigger IBS-like bowel urgency or loose stools.

That said, diarrhea isn’t specific to adenomyosis, and bowel symptoms are often a clue that more than one issue may be contributing—most commonly endometriosis (which can involve tissue outside the uterus) and/or bowel sensitivity patterns that overlap with pelvic pain conditions. If your diarrhea is cyclical, paired with heavy bleeding or severe cramping, or persists after other treatments, our team can help evaluate the full picture—uterus, pelvis, and bowel—so the treatment plan matches the true drivers of your symptoms. If you’d like, you can reach out to schedule a consultation with us to review your history and imaging and map out next steps.
