Can endometriosis cause heart palpitations?

Yes—some people with endometriosis (and adenomyosis) report heart palpitations, especially during pain flares, high-stress periods, or around hormonal shifts. One reason is that chronic pelvic pain and inflammation can keep the nervous system in a more “alarm” state, which can affect autonomic regulation (the balance between fight‑or‑flight and rest‑and‑digest) and make your heart rate feel more noticeable or irregular. Palpitations can also show up alongside other whole‑body symptoms some patients describe, like dizziness, temperature intolerance, fatigue, and sleep disruption.

At the same time, palpitations aren’t specific to endometriosis, and we don’t assume they’re “just endo.” Our approach is to look at the whole picture—your cycle pattern, pain history, medications/hormonal treatments, anemia from heavy bleeding, thyroid issues, and cardiac risk factors—so we don’t miss a separate (and treatable) cause. If palpitations are new, worsening, or tied to chest pain, shortness of breath, fainting, or significant lightheadedness, that deserves prompt evaluation; if you’d like, reach out to schedule a consultation so our team can help you sort out what’s driving your symptoms and how to address both the disease and the nervous-system component.
