What to know about endometriosis
Endometriosis is a disorder in which tissue that normally lines the inside of your uterus — the endometrium — grows outside your uterus.
Endometriosis most commonly involves your ovaries, fallopian tubes, and the peritoneum (the tissue lining your pelvis).
Rarely, endometrial tissue may spread beyond pelvic organs.
Endometriosis can cause pain — sometimes severe — especially during menstrual periods.
Fertility problems also may develop.
With endometriosis, displaced endometrial tissue continues to act as it normally would — it thickens, breaks down and bleeds with each menstrual cycle. Because this displaced tissue has no way to exit your body, it becomes trapped. When endometriosis involves the ovaries, cysts called endometriomas may form. Surrounding tissue can become irritated, eventually developing scar tissue and adhesions which can cause pelvic tissues and organs to stick to each other.
Although there is no real cure, effective treatments are available.
