However, if you experience the absence of regular periods, it's recommended that you consult your health care provider. While lack of bleeding alone is not necessarily harmful, it can signal a low level of estrogen, which can eventually cause bone loss. Less commonly, endometriosis may occur on the bowel or bladder. These fragments respond to the hormonal changes of each menstrual cycle by growing, then being shed as blood, the same way as the endometrial membrane does in the uterus. The blood and other material can irritate or damage adjacent tissue, and scars may form.
Endometriosis can even lead to infertility.
Symptoms of endometriosis include chronic pain in the lower abdomen, especially during periods, pain during or after sexual intercourse, painful bowel movements, and irregular menstrual cycles. Endometriosis may also exist without any symptoms. Treatment options vary from medication to radical surgery, and depend on the extent of the condition. For more information on endometriosis, contact a health care provider. It may be mild or severe, chronic or acute, and is usually the result of an infection or a hormonal change.
