Endometriosis, a painful condition that affects women of all ages, is very common. Endometriosis affects approximately 10% of women aged 16-45. Endometriosis is defined as any condition that involves the use of menstruation. Endometriosis is uncommon in women who have never experienced menstruation, or who have stopped having menstruation because of menopause. Endometriosis can be caused by many factors. There are many risk factors, including smoking and a family history of endometriosis. These are possible causes of endometriosis, although studies are not conclusive.
Endometriosis causes and symptoms occur when bits of the tissue that lines the uterus (endometrium) grow on other pelvic organs. Also, it can be caused by the presence of primitive cells, which can transform into other types of tissue. This is known as coelomic Metaplasia. These primitive tissues can be found in certain areas of the pelvic organs. They can then grow into endometrial cell-like cells and act the same as endometrial tissues, even though they are not in the uterus.

Endometriosis may also occur in rare cases due to the direct transfer of endometrial tissue. This can happen during surgery like episiotomy and cesarean section. Endometriosis implants can be found in the brain or other organs far from the pelvis. This is thought to be due to endometrial cells being transported through the lymphatic system or bloodstream.
Possible causes of endometriosis include hormonal fluctuation. The symptoms can be more severe during periods or before. Hormonal levels are subject to fluctuation during menstrual cycles. Women with these conditions have stable hormone levels, so endometriosis symptoms are not present. Endometriosis may be caused by abnormalities in the immune response, according to some studies.
