Risk factors for bacterial vaginosis include:

  • Multiple sex partners or a new sex partner. The link between sexual activity and bacterial vaginosis isn't entirely clear, but bacterial vaginosis occurs more often in women who have multiple sex partners or a new sex partner. Bacterial vaginosis also seems to occur more frequently in women who have sex with women.
  • Douching. The practice of rinsing out your vagina with water or a cleansing agent (douching) upsets the natural balance of your vaginal environment. This can lead to an overgrowth of anaerobic bacteria, which in turn can result in bacterial vaginosis. Since the vagina is self-cleaning, douching isn't necessary.
  • Natural lack of lactobacilli bacteria. If your natural vaginal environment doesn't produce enough of the good lactobacilli bacteria, you're more likely to develop bacterial vaginosis.
