Dear angelgal077,

Each month, when a woman gets her period, the lining of the uterus (which is called the endometrium) breaks down and is shed as menstrual flow. When a woman has endometriosis, the kind of tissue that makes up the lining of the uterus also grows in other parts of her body, including the ovaries, the bowels, and the bladder. During her period, this tissue breaks down — but since it's outside the uterus, it can't leave the body during menstruation, and cysts and scar tissue may form as a result.

Symptoms of endometriosis include

• pelvic or abdominal pain, especially during ovulation and menstruation
• back pain, especially during menstruation
• heavy, lengthy, or irregular periods
• painful bowel movements and urination
• pain during or after vaginal intercourse
• nausea and vomiting
• diarrhea or constipation

While no one is 100 percent sure of what causes endometriosis, researchers believe the condition may be somewhat hereditary. For example, if your mother or grandmother had or has endometriosis, you may be more likely to have the disorder.

Endometriosis often causes infertility, but not always. Endometriosis is difficult to diagnose because it can resemble other conditions. It's best to consult a clinician who will be able to run the necessary tests used to diagnose endometriosis. Call 1-800-230-PLAN to schedule an appointment at a Planned Parenthood near you.

Hope this information helps!

Take care,
