During pregnancy a woman's body works overtime to grow another being. As a result, her immune system is compromised. Acidophilus bifidus supplements increase good bacteria in the gut. This flora combats any bad bacteria that may be present, relieving a variety of maladies---including those specific to pregnancy---in the process.
Acidophilus Bifidus Defined
The World Health Organization defines acidophilus bifidus, also called probiotics, as "live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host." Probiotics are found in certain foods and may also be purchased in pill or powder form from natural grocers and pharmacies.
History
"Mothering" magazine points out that while acidophilus bifidus is not a traditionally valued part of the American diet, "it has been traditionally eaten for thousands of years in various cultures around the world." Acidophilus bifidus occurs naturally in fermented foods such as kimchi, yogurt, miso and kefir. Russian microbiologist Elie Metchnikoff won a Nobel Prize in 1908 for his research proving the efficacy of acidophilus bifidus in fighting infection and inflammation and for enhancing overall immune system function.
Official Statements
American Congress of Obstetricians and Gynecologists does not have an official statement on acidophilus bifidus during pregnancy. The supplement is regulated by the U.S. Food & Drug Administration and acknowledged by the National Institutes of Health as a complementary and alternative medicine.
Research
The NIH says evidence supports the efficacy of acidophilus bifidus in treating diarrhea and urinary tract infections, two common complaints of pregnant women. According to "Mothering" magazine, acidophilus bifidus benefits the baby as well. The healthy bacteria colonizes the mother's vagina, and, as the baby passes through during birth, she becomes naturally inoculated. The beneficial bacteria also transfers through the mother's breast milk, offering further immunity to her baby.
Risks
Harmful side effects of acidophilus bifidus are rare, according to the NIH. If taken in large amounts, gas or bloating may occur. Only occasionally can the immune system be hyperstimulated by acidophilus bifidus. The NIH hypothesizes that, in those with compromised immune systems---such as pregnant women---the supplement could actually cause infection that would need to be treated with antibiotics. Pregnant women should discuss supplement usage and side effects with their obstetricians or midwives.
