Acidophilus is a colloquial name for a bacterial species more properly known as Lactobacillus acidophilus. These bacteria don't cause infection in humans; instead, they're part of the normal flora of the intestinal tract and, in the case of women, of the vagina. There may be certain uses for acidophilus during pregnancy.
Pregnancy and Digestion
There are several common concerns and complaints associated with pregnancy for which some health practitioners recommend acidophilus. The first is that during pregnancy, the action of your digestive tract slows down. This leads to increased gas, bloating, and constipation. Some studies, like a 1961 study published by Dr. C. Beck and colleagues in the "American Journal of Gastroenterology," suggest that administration of Lactobacillus acidophilus -- as obtained through consumption of yogurt and other fermented dairy products -- can help digestive disorders.
Pregnancy and Yeast
Another potential use for acidophilus in pregnancy is the prevention of yeast infections and other common vaginal infections. Acidophilus bacteria normally cultivate the vagina, and help maintain its natural acidity and pH balance. During pregnancy, hormonal changes can make you more prone to vaginal infection by yeast or certain bacterial species. Lactobacillus acidophilus consumption can help prevent yeast infections. It is also possible to introduce yogurt -- plain and unsweetened -- directly into the vagina, provided you have your doctor's permission.
Safety and Use
During pregnancy, Lactobacillus acidophilus is thought to be safe for use. As such, consuming supplemental acidophilus may help reduce several pregnancy-related conditions. Sources of acidophilus include yogurt, kefir, buttermilk, and other fermented dairy products. In general, these fermented dairy products will not only contain acidophilus, but they will also be easier for you to digest than non-fermented dairy. You can also purchase over-the-counter acidophilus supplements.
Warning
While acidophilus can help prevent vaginal bacterial and yeast infections, you shouldn't attempt to treat infections yourself by using oral or vaginal acidophilus. This is because there are some vaginal bacterial infections that can become very severe during pregnancy and increase your risk of premature labor and delivery, explain Heidi Murkoff and Sharon Mazel in their book "What To Expect When You're Expecting." If you suspect you have a vaginal infection during pregnancy, talk to your doctor.
