Dear joan1,

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 shows up 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

If you are experiencing symptoms like those of endometriosis, it is important that you talk to your clinician. Only a clinician can diagnose and treat endometriosis.

Hope this information helps!

Take care,
