Bowel symptoms that flare with periods: IBS or bowel endometriosis?

Bowel symptoms that reliably flare around your period—like diarrhea, constipation, painful bowel movements, rectal pressure, or deep pelvic pain—can be a pattern we see with bowel endometriosis. IBS symptoms can overlap, but they’re more often tied to food triggers, stress, or a more day-to-day course rather than a consistent menstrual cycle link.

Because the symptoms can look so similar, the most helpful next step is a thorough history focused on timing, associated pelvic pain, bleeding, and how symptoms behave outside of menses. Our team can also coordinate an appropriate gastrointestinal workup when needed to rule out other bowel conditions, and we may recommend targeted imaging to look for signs of endometriosis and better define what might be driving your flares. If your symptoms are cyclical or worsening, reaching out to schedule a consultation can help us map out a clear plan for diagnosis and treatment options.
