A fibroid is a tumor in the muscle of the uterus. It sounds dire, but in reality pregnant women with fibroids have a very good chance of delivering healthy babies.

Facts about Fibroids

Fibroids vary greatly in size. They can be microscopic, the size of a pea, or the size of a baseball. Some fibroids are even larger than that. They are commonly found in women ages 30 to 50, so most women with fibroids have already had, or at least started, their families. Even so, only about 20% of women find their fibroids interfere with daily life. Most women show no symptoms and experience no pain or discomfort from them.

Still, you may be a woman in your late thirties or forties wondering if fibroids can harm your baby. It's a natural curiosity since uterine fibroids exist in the uterus where the fetus develops. But actually, fibroids almost never have an affect on a woman or her baby.

Their Affect on Pregnancy

Let's say you aren't pregnant, but have plans on trying to conceive and don't want fibroids to interfere. The good news is that they probably won't. If your fibroids change the shape of your uterine cavity they can decrease fertility by 70%, but most fibroids do not do that. Instead, they stay small in size and do not decrease your chance of pregnancy at all.

If you are pregnant and worried about the well-being of your baby, it is important to note that fibroids can cause miscarriages. If your fibroid enters the uterine cavity, it can possibly decrease blood flow to the fertilized egg, causing the embryo to develop improperly. If you experience a miscarriage and a fibroid is found, it is advised that you have it removed.

Now if you're farther along in your pregnancy and you have fibroids, don't fret. You have a very high chance of delivering a perfectly healthy baby. In fact, only four babies in the past 25 years were affected by a fibroid - so it's extremely rare. You may need a caesarean section when it comes time to deliver, as many women with fibroids do, but there shouldn't be any complications.

Advice for Pregnant Women with Fibroids

Make sure you eat lots of fiber - fruits, green leafy vegetables, whole grains, etc. Try to stay away from dairy products or, if you simply can't, buy organic milk and yogurt. Don't consume as much red meat and don't buy fish raised at a farm. Try to get it wild and fresh. And of course, be sure to drink plenty of water - 8 glasses a day should be fine.

During pregnancy, your body will produce more estrogen and progesterone, which will cause the fibroids to grow. If there is more estrogen than progesterone, this can make your fibroids grow even faster. In that case, take a natural progesterone supplement to help balance out this estrogen dominance. It could slow the growth of your fibroids or even stop it completely.


During pregnancy, doctors will advise you to leave the fibroid alone and not remove it. However, its size and growth will be monitored for the safety of you and your baby. If you're in any pain, just lay down and relax. Grab an ice pack and place it on your abdomen if necessary. If the pain is severe or you experience profuse bleeding, contact your doctor right away.

After pregnancy, the fibroid will shrink and will likely not cause you any harm for the rest of your life. If you have any concerns, though, it can be treated. There are five ways: the fibroids can be ablated, you can have a hysterectomy, take medications to shrink the fibroids, undergo surgery to remove them, or take up natural treatments.

If you think you may have a fibroid, the best way to find out is to get an MRI. That might be a bit expensive, especially if you want to check regularly, but there are other methods as well. Sonograms, vaginal probe ultrasounds, and a hysteroscopy (telescope) can also be used to detect fibroids.
