Pelvic Pain: Uterine Fibroids vs. Endometriosis

Fibroids can cause severe menstrual pain, but so can endometriosis. What’s the difference between these two conditions? Uterine fibroids are benign lumps of muscle and connective tissue that grow on the uterine wall. Nearly one in four women over 35 is affected.

Most uterine fibroids are harmless and don’t cause symptoms. However, fibroids can cause a feeling of moderate pelvic pressure at any time. And the closer they are to the uterine lining, the heavier the menstrual flow. It may last longer than seven days and/or cause a need to change tampons every hour or two. Discomfort or pain during intercourse can also occur with uterine fibroids. Other symptoms include an irregularly shaped uterus which may put pressure on the bowel and/or bladder. This can result in difficulty with bowel movements, constipation, urinary frequency, incontinence and backaches. Reproductive problems include recurring miscarriage, infertility and labor complications.

Endometriosis is a condition where the type of tissue that lines the uterus also grows outside the uterus, usually on the ovaries, the fallopian tubes, the outer wall of the uterus, the intestines, or other organs in the abdomen. Since they are the same type of cells that usually line the uterus, they respond to estrogen and grow a little each month and sometimes slightly bleed. As this tissue is outside of the uterus, blood cannot flow out of the body and therefore can cause irritation and pain. Symptoms for endometriosis may include heavy periods, painful menstrual cramps, bloating, constipation and/or diarrhea.

This painful condition affects up to one in three women. Unfortunately it takes an average of 10 years to diagnose endometriosis after symptoms start, partly because so many women think it’s merely severe menstrual cramps.
