It develops when there's an imbalance between the "good" bacteria in the vagina that are helpful and the "bad" bacteria that can cause problems.
Bacterial vaginosis may cause pain, itching, and a bad-smelling discharge. But most girls with BV don't notice any symptoms — and that's not necessarily a good thing. Symptoms alert us to signs of trouble. Girls who don't know they have BV might not get treated for it. BV may be mild, but if it isn't treated it can lead to other problems. BV is the most common vaginal infection affecting young women. Although it's not considered a sexually transmitted disease STD , the chances of developing bacterial vaginosis seem to increase with the number of sexual partners a woman has.
You don't need to be having sex to get BV, though. Girls who've never had sex also can get it. Normally, a lot of good, healthy bacteria live in the vagina along with a small amount of potentially harmful bacteria. But sometimes this balance can be upset by things like douching.

Treating BV The usual treatment for BV is prescription antibiotics pills, vaginal creams, or suppositories. Because BV can come back, a girl may need to take more than one series of antibiotics. Even if you feel better partway through taking the antibiotics, you'll need to take all the pills or use all the cream or suppositories.
Your health care provider should let you know about any restrictions needed while taking the antibiotic. For example, some medications can weaken condoms and diaphragms even after the treatment is finished. With other medications, people can't drink alcohol. Ask if there's anything you should avoid while taking your medication.
If a girl is having sex, her male sex partners probably won't have to get treated, but female partners will. Can It Be Prevented? It's not always possible to prevent BV. But these things can lower a girl's chance of getting it: But if it's not treated, BV can increase a girl's chances of certain health problems: Increased chance of getting an STD: Increased chance of pregnancy complications: When BV isn't treated, a woman may have more problems when she gets pregnant, such as premature birth, low birth weight, infection, and possibly miscarriage.
Infections like BV are one reason why girls who are having sex need to get regular gynecological checkups and STD tests. Even if a girl doesn't know that she has an infection, doctors and nurse practitioners can diagnose and treat it to help prevent complications.
