Symptoms of Endometriosis

Patients with endometriosis can have symptoms varying from constant excruciating pelvic pain to no symptoms whatsoever. Paradoxically, the extent of endometriosis has no correlation to the amount of pain a women will experience. Some women with severe endometriosis do not have any symptoms and may not know they have endometriosis until a pelvic mass is detected on a routine pelvic examination or a problem with infertility is discovered. The following are the common symptoms of endometriosis, but remember that women with endometriosis may have all, some, or none of these symptoms.

Pain and Discomfort in the Pelvic area

Women with endometriosis most commonly experience increasing pain and discomfort right before and during their monthly cycles. Painful sexual intercourse, pressure and bloating in the lower abdomen, and severe, sometimes incapacitating, cramps during this period are not uncommon. Some women with endometriosis, however, have constant pelvic pain, cramps, and painful intercourse which may not be associated with monthly cycles.

Abnormal Uterine Bleeding

A women with endometriosis may have some vaginal spotting a few days before and/or after her period, or she may have abnormally heavy and long periods.

Gastrointestinal symptoms

Gastrointestinal dysfunction ranges from abdominal bloating or nausea to intestinal cramps, cycles of diarrhea and/or constipation. Rectal bleeding and painful bowel movements may occur when the rectum and sigmoid colon are invaded by the endometriosis.


The most common cause of unexplained female infertility is endometriosis.

Urinary symptoms

Frequency, urgency, bladder pain, and occasionally bloody urine may occur when endometriosis has involved the bladder. Endometriosis can invade the ureter (tube between the kidney and the bladder), may cause obstruction of the ureter, and damage the kidney.
