The medical definition for endometriosis is as follows. Normally, the endometrium builds up and passes during menstruation. Both the glands and stroma must be present for diagnosis of endometriosis. Several parts of the body can be affected by endometriosis including the uterus, the outer surface of the uterus, the supporting ligaments, Fallopian tubes, ovaries, and pelvic cavity lining. Other areas may include the bladder, bowel, vagina, rectum, cervix or vulva.
Endometriosis can also occur in almost any organ of the body including the heart and lungs.
Endometriosis found in unusual sites of the body such as the thumb, thigh or knee, have been diagnosed to have been contracted before birth in the early stages of development. Predominately, endometriosis occurs in women in their reproductive years. However, endometriosis has been diagnosed in prepubertal girls, adolescent girls, women who have never menstruated, in post-menopausal women and even in men. All rights reserved.
