Uterine Fibroids and Pregnancy

Uterine fibroids are noncancerous growths that can develop in or on the uterus. They can be as small as a pea or as large as a grapefruit. Most women who have been diagnosed with fibroids go on to have normal pregnancies, but sometimes fibroids can cause challenges.

Many women have fibroids, but not everyone has symptoms. An estimated 40% to 60% of women have fibroids by age 35.

Symptoms of fibroids include heavy menstrual bleeding, pelvic pain, peeing often, and possible complications during pregnancy.

Fibroids can lead to pain, a higher likelihood of needing a C-section, preterm delivery, and sometimes placental abruption. This means your placenta tears away from the wall of your uterus before your baby is delivered. Placental abruption is a serious condition that happens in about 1% of all pregnancies.

It’s important to manage pain and discomfort caused by fibroids during pregnancy. Over-the-counter medications like acetaminophen (Tylenol) can help. But avoid nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen because they may cause you to miscarry or affect the health of your baby. 

Keep track of any changes or new symptoms and let your doctor know. Each pregnancy is unique, and having fibroids doesn't mean you'll have trouble with pregnancy and childbirth. Many women with fibroids have normal, healthy pregnancies and deliveries.
