Every month, a woman’s ovaries produce hormones that tell the cells lining the uterus (womb) to swell and get thicker. The body removes these extra cells from the womb lining (endometrium) when you start your period.
If these cells (called endometrial cells) implant and grow outside the uterus, endometriosis results. The growths are called endometrial tissue implants. Women with endometriosis typically have tissue implants on the ovaries, bowel, rectum, bladder, and on the lining of the pelvic area. They can occur in other areas of the body, too.
Unlike the endometrial cells found in the uterus, the tissue implants outside the uterus stay in place when you get your period. They sometimes bleed a little bit. They grow again when you get your next period. This ongoing process leads to pain and other symptoms of endometriosis.
The cause of endometriosis is unknown. One theory is that the endometrial cells shed when you get your period travel backwards through the fallopian tubes into the pelvis, where they implant and grow. This is called retrograde menstruation. This backward menstrual flow occurs in many women, but researchers think the immune system may be different in women with endometriosis.
Endometriosis is common. Sometimes, it may run in the family. Although endometriosis is typically diagnosed between ages 25 – 35, the condition probably begins about the time that regular menstruation begins.
A woman who has a mother or sister with endometriosis is much more likely to develop endometriosis than other women. You are more likely to develop endometriosis if you:
Treatment to stop the endometriosis from getting worse often involves using birth control pills continuously for 6 – 9 months to stop you from having periods and create a pregnancy-like state. This is called pseudopregnancy. This therapy uses estrogen and progesterone birth control pills. It relieves most endometriosis symptoms. However, it does not prevent scarring or reverse physical changes that have already occurred as the result of the endometriosis.
Hormone therapy and laparoscopy cannot cure endometriosis. However, these treatments can help relieve some or all symptoms in many women for years.
Removal of the womb (uterus), fallopian tubes, and both ovaries (a hysterectomy) gives you the best chance for a cure. Rarely, the condition can return.
Endometriosis can lead to problems getting pregnant (infertility). Not all women, especially those with mild endometriosis, will have infertility. Laparoscopy to remove scarring related to the condition may help improve your chances of becoming pregnant. If it does not, fertility treatments should be considered.
Other complications of endometriosis include:
In a few cases, endometriosis implants may cause blockages of the gastrointestinal or urinary tracts. This is rare.
Very rarely, cancer may develop in the areas of endometriosis after menopause.
Call for an appointment with your health care provider if:
Consider getting screened for endometriosis if your mother or sister has been diagnosed with endometriosis, or if you are unable to become pregnant after trying for 1 year.
Birth control pills may help to prevent or slow down the development of the endometriosis.
Pain is the main symptom of endometriosis. A woman with endometriosis may have:
Note: There may be no symptoms. Some women with a large number of tissue implants in their pelvis have no pain at all, while some women with milder disease have severe pain.
Dr. Corney will perform a physical exam, including a pelvic exam. Tests that are done to help diagnose endometriosis include:
Treatment depends on the following factors:
If you have mild symptoms and do not ever want children, you may choose to have regular exams every 6 – 12 months so the doctor can make sure the disease isn’t getting worse. You can manage your symptoms by using:
For other women, treatment options include:
Surgery may be recommended if you have severe pain that does not get better with other treatments. Surgery may include:
