Causes
Bacterial vaginosis is caused when the normal balance of bacteria in the vagina is disrupted. Normally, the vagina has helpful bacteria ( lactobacilli ), as well as more harmful bacteria (anaerobes—bacteria that do not need oxygen to live).
Sometimes the harmful bacteria overgrow, and not enough helpful bacteria are left in the vagina. The cause of this overgrowth is not understood. In some cases, it may be related to sexual activity through transfer of harmful bacteria from a sexual partner.
Risk Factors
The following factors increase your chances of developing bacterial vaginosis:
- Smoking
- Using douches or feminine sprays
- Having sex without a condom
- Having a new sexual partner or multiple partners
- Using an intrauterine device (IUD) for birth control
