Bacterial vaginosis (BV) results from overgrowth of one of several organisms that are normally present in the vagina, upsetting the natural balance of vaginal bacteria. More than one in six women in the United States has bacterial vaginosis, though many aren’t aware of having it.
Bacterial vaginosis (BV) results from an overgrowth of organisms that are normally present in the vagina. Usually, “good” bacteria outnumber “bad” bacteria in your vagina. But if bad bacteria become too numerous, they upset the balance and bacterial vaginosis results. This type of vaginitis (bacterial vaginosis) can spread during sexual intercourse, but it also occurs in people who aren’t sexually active. Women with new or multiple sex partners, as well as women who douche or use an intrauterine device (IUD) for birth control, have a higher risk of bacterial vaginosis.
