What is bacterial vaginosis? Learn about the risk factors, symptoms and how it’s treated.
If you’ve been experiencing unusual vaginal discharge or uncomfortable vaginal symptoms, you may have a common infection called bacterial vaginosis (BV). About 35% of women, usually between the ages of 15 and 44, have BV at some point in their life.
Some people have no symptoms, but if left untreated, BV increases your risk of getting asexually transmitted infection (STI) and other complications. If you think you might have BV, contact your healthcare provider (HCP) as soon as you can.
BV is an infection, but it’s not an STI.
Your vagina normally has many types of bacteria in it. The so-called “good” bacteria help keep your vagina healthy by keeping harmful bacteria in check. If the harmful bacteria outnumber the good ones, the overgrowth and imbalance can cause BV. Women who are not sexually active don’t usually get BV, but it’s possible.
Any person with a vagina can get BV, but certain situations raise that risk:
Not everyone with BV has symptoms. The most common symptom is unusual vaginal discharge. Some women describe it as smelling like fish, especially after sex. The color of the discharge can range from off-white to greenish. Other symptoms include:
If you’re pregnant, vaginal discharge isn’t unusual. Discharge during pregnancy is typically thin and whitish, and has a mild odor. If you develop a thicker discharge that has a strong odor, contact your HCP.
Keep in mind that yeast infections can cause the same symptoms as BV. If you used over-the-counter yeast infection treatment to treat your symptoms, but they didn’t go away, you may have BV.

To diagnose BV, your HCP will need to do a pelvic exam. They’ll examine your vagina and the area around it. If they think you might have BV, they’ll take a sample of the discharge to send to a lab for testing.
Although you can’t pass BV on to a male partner, you can pass it to a female partner. So, if you have a sexual relationship with a person with a vagina, it’s important to tell that person about your diagnosis.
The most common antibiotics used to treat BV are metronidazole and clindamycin. You can take antibiotics in pill form or apply a gel or cream directly into the vagina with an applicator.
It’s important to complete the entire prescription, even if your symptoms go away before the medication is finished. The bacteria may still be present and the symptoms will return if you stop the medication too soon. There’s also the risk that bacteria will become antibiotic-resistant. Even after completing a course of antibiotics, about 10–15% of people need more treatment. And up to 8 out of 10 people will have a repeat infection at some point in their life.
Although BV is usually cured with treatment, there are complications to be aware of if the infection is not treated. These include:
