What is Endometriosis?
Endometriosis means that the tissues of the uterus are growing outside the uterus. Every month, a woman's uterine lining sheds during her period if she's not pregnant. With endometriosis, the displaced tissue "continues to act as it normally would — it thickens, breaks down and bleeds with each menstrual cycle," according to the Mayo Clinic.
Endometriosis is typically seen during the reproductive years; it has been estimated that endometriosis occurs in roughly 6–10% of women. Symptoms may depend on the site of active endometriosis. Its main but not universal symptom is pelvic pain in various manifestations. Endometriosis is a common finding in women with infertility.
