Bacterial Vaginosis (BV)

Bacterial vaginosis is a condition that happens when there is a change in the normal balance between the "good and "bad" bacteria in the vagina.

What causes BV?

The cause of BV is unknown, but it typically occurs in sexually active women. New sex partner or multiple sex partners, and douching, can upset the PH balance in the vagina, thus causing BV.

  • A thin white or gray vaginal discharge
