Endometriosis is a condition in which tissue that normally lines the uterus grows outside of the uterus. This tissue, which does not belong outside the uterus, becomes trapped and can cycle with your period, bleed, and cause symptoms like pain. It can also cause irritation that can lead to scarring and “adhesions,” which are abnormal bands of tissue that can cause organs to stick to each other. Endometriosis can lead to trouble getting pregnant.
The cause of endometriosis is not known. You could ask your doctor or the study doctor about this.
There is no simple test for endometriosis. A doctor or nurse may suspect that you have endometriosis if you have painful menstruation (“your monthly cycle”). The only way to diagnose endometriosis is for a doctor to do surgery. This surgery is typically a “laparoscopy,” a surgery in which a doctor makes a small cut in the belly and inserts a tube with a camera. This allows the doctor to see, and sometimes remove, endometriosis tissue.
Treatment options include oral medicines, injectable medicines, and surgery, all of which have pros and cons.
