A recent study shows that bacterial vaginosis (BV) is risky during pregnancy. Since up to 30% of women have BV, this is an obvious problem.

BV is thought to be the most common vaginal infection in women of childbearing age. BV is basically when the normal balance of bacteria in the vagina is compromised in some way. Usually BV results in itching, burning, or odd discharge.

How BV affects pregnancy: The new study showed that women who develop BV in their second trimester are more likely to have low-birth weight babies and may suffer from chorioamnionitis (infection of placenta and amniotic fluid). Since so many women get BV this is a huge issue.

What you can do: If you’re pregnant, watch for signs of BV, which according to the CDC can include; “Abnormal vaginal discharge with an unpleasant odor. Some women report a strong fish-like odor, especially after intercourse. Discharge, if present, is usually white or gray; it can be thin. Women with BV may also have burning during urination or itching around the outside of the vagina, or both. ” If you notice symptoms, tell your doc or midwife. BV is easily treated with antibiotics.

You will not be screened for BV during prenatal appointments unless you report symptoms, have a history of early labor, or your membranes rupture early. Since you likely won’t be randomly screened, and many women don’t even notice symptoms, prevention is your best bet.

To prevent BV: Don’t douche or use fragrances or scented soaps down you know where. All of these can disrupt your natural bacterial balance.
