Endometrosis occurs when tissue, similar to the lining of the endometrium, grows outside the uterus. The tissue that grows outside the uterus in endometriosis is not the same as endometrial tissue, but they have some features in common.
The tissue can develop anywhere in the body, but it usually affects the pelvic area, including:
the ovaries
the fallopian tubes
tissues that support the uterus
the outside of the uterus
The women who have Endometriosis may experience heavy bleeding during their menstrual cycle and may have painful periods. It may adversely affect their fertility by weakening the lining of the uterine wall. It may also cause general listlessness and depression.
