Bacteria Vaginosis (BV)

Bacterial vaginosis

Bacterial vaginosis (BV) is a common gynecologic infection, affecting nearly 29 percent of women in the U.S. While not all women with BV have symptoms, those that do may experience an abnormal vaginal discharge that may be white or gray, watery, and may also have a strong fish-like odor, or vaginal itching and irritation.

How does someone get BV?

In a healthy vagina, there is a balance among many kinds of bacteria. Some kinds of bacteria are considered “helpful” while others are “less helpful.” Helpful bacteria help keep the vagina a little bit acidic. This keeps less helpful bacteria from growing too fast. Sometimes, though, the less helpful bacteria can take over, and the result may be BV.

Anyone with a vagina can get BV, but there are some things that may increase the chance of someone getting BV, like douching or having new or multiple sex partners.

Diagnosing BV

Correct diagnosis is important. Untreated, BV can increase a woman’s risk of sexually transmitted infections (STIs), including HIV. Pregnant people can face additional problems, as BV may cause babies to be born early or with low birth weight.

Women may mistake the generic symptoms of BV—like itching and discharge—for a yeast infection. While it can be tempting to self-diagnose and self treat with over-the-counter products, it’s easy to misdiagnose the problem. In a 2017 ASHA survey, 62 percent of women mistook BV for a yeast infection prior to diagnosis. If it is BV, medication for a yeast infection won’t help.

Only a healthcare provider can accurately diagnose BV. Your provider will likely perform an exam and take a sample of vaginal discharge. The provider may examine the sample under a microscope in the office or send it to a lab to be tested.

Treatment

BV can be treated with antibiotics, including a one-day, one-dose treatment. However BV can come back in the months after treatment, so if symptoms come back, talk to a provider.

A Healthy Vagina is a Happy Vagina

Fortunately, the vagina is designed to keep itself clean with natural, healthy vaginal secretions. You can keep your vagina healthy with the same things that keep your whole body healthy—regular hygiene and a good diet. Here are a few basic tips:

Don't Douche

While some women douche thinking it keeps the vagina clean, it actually does more harm than good. Douching upsets the natural balance of the vagina and may make you more prone to vaginal infections.

Keep Clean

Wash your vaginal area with mild, unscented soap. There is no need to use anything special to clean the vulva and vagina. Also remember to wipe your vagina and anus from front to back to avoid spreading germs.

Get Help

If you have symptoms of an infection, like discharge or irritation, see a provider to find out what's going on. It may be BV, or it may be another problem like a yeast infection or an STI. Only a provider can make a correct diagnosis.
