Bacterial Vaginosis

Bacterial Vaginosis Basics
Bacterial Vaginosis (BV) is the name of a condition in women where the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria. It is sometimes accompanied by discharge, odor, pain, itching, or burning.

Bacterial Vaginosis (BV) is the most common vaginal infection in women of childbearing age. In the United States, as many as 16 percent of pregnant women have BV.

How Do People Get Bacterial Vaginosis?
The cause of BV is not fully understood. BV is associated with an imbalance in the bacteria that are normally found in a woman's vagina. The vagina normally contains mostly "good" bacteria, and fewer "harmful" bacteria. BV develops when there is an increase in harmful bacteria.

Not much is known about how women get BV. There are many unanswered questions about the role that harmful bacteria play in causing BV. Any woman can get BV. However, some activities or behaviors can upset the normal balance of bacteria in the vagina and put women at increased risk including:

  • Having a new sex partner or multiple sex partners,
  • Douching,
  • Using an intrauterine device (IUD) for contraception.

It is not clear what role sexual activity plays in the development of BV. Women do not get BV from toilet seats, bedding, swimming pools, or from touching objects around them. Women that have never had sexual intercourse are rarely affected.
