What is endometriosis?
The endometrium is the inner lining of the uterus, which changes throughout the menstrual cycle, shedding during menstrual periods. Endometriosis is the presence of normal endometrial tissue abnormally implanted in locations other than the inner wall of the uterus.
The abnormally located endometrial tissue (endometrial implant) nevertheless responds to natural cyclic hormonal fluctuations in much the same way as the tissue located in the uterus. The result is, thickening, hormone secretion and cyclic sloughing of menstrual material. Thus, the symptoms of endometriosis depend on the cyclic production of menstrual hormones as well as where it has spread.
