Better Life Through Better Health

Bacterial Vaginosis (BV) is a common infection in women caused by an overgrowth of bacteria normally found in low levels in the healthy vagina. BV occurs when the normal balance of organisms in the vagina is disrupted and the bacteria level grows high. It is not clear what exactly causes BV. Once named after certain organisms thought to cause the infection, BV has been called Haemophilus vaginitis, Gardnerella vaginitis or nonspecific vaginitis. These terms are now outdated, as no one organism seems to cause BV.

BV can affect women at any stage of life. Since BV is not a sexually transmitted disease, women who are not sexually active can develop BV. Male partners usually do not need treatment, although some men may pick-up and harbor the organisms from a partner with BV and reinfect her or others later. Symptoms are rare in males.

BV may cause babies to be born early or with low birth weight. It can also cause infections in the mother’s womb or fallopian tubes. Over 800,000 pregnant women are diagnosed with BV each year in the US. Symptoms of BV are a thin, grayish vaginal discharge, itching, and burning. A "fishy" or ammonia odor is often present.

Women often mistake the symptoms of BV for a yeast infection. Over the counter treatments for yeast are not effective against BV. Women with symptoms should visit their health care provider for proper treatment. To prevent BV avoid tight clothing that can trap moisture. Wear panty hose and underwear with a cotton crotch. Wipe from front to back after a bowel movement or urinating. Avoid harsh soaps, douches or feminine hygiene sprays, unless advised by a health care provider.
