Can endometriosis cause breathing problems?

Yes—endometriosis can cause breathing-related symptoms in a small subset of patients when disease involves the diaphragm, the lining around the lungs, or (more rarely) the lungs themselves. This is often discussed under the umbrella of thoracic endometriosis syndrome, and it can show up as shortness of breath, chest tightness or pain, shoulder pain, or even a recurrent collapsed lung. A major clue is timing: symptoms that reliably flare just before or during your period are more suspicious for endometriosis-related chest involvement than symptoms that are random.

Because imaging doesn’t always clearly “show” thoracic or diaphragmatic endometriosis, diagnosis often depends on your symptom pattern plus a careful whole-body evaluation and, in some cases, minimally invasive surgery to confirm and treat disease. If you’re noticing cyclical chest or breathing symptoms—especially if you also have pelvic pain, heavy bleeding, bowel/bladder symptoms, or infertility—our team can help connect the dots, coordinate appropriate workup, and discuss treatment options that may include targeted hormonal suppression and/or planned excision with the right surgical team (including thoracic expertise when needed).
