Bacterial vaginosis (BV)

Bacterial vaginosis (BV) is a condition where the balance of bacteria inside the vagina becomes disrupted. Sometimes you can get too many of one bacteria, namely gardnerella vaginalis.

How do you get bacterial vaginosis?

You can get BV without sexual contact, but it is often linked with sexual activity.

How do I know I have bacterial vaginosis?

Some women get BV and have no symptoms at all. Some women get a grey discharge from the vagina with a fishy or musty smell. The smell can get stronger after sex or during your period. At Marie Stopes, we can do a simple ‘PH’ test which can be used to assist in the diagnosis of BV. In addition we can send a sample to a laboratory and this can also be tested for other STIs like chlamydia.

How do I get treated for bacterial vaginosis?

We can treat BV using antibiotics or by applying a cream. If you are pregnant you may need to see a specialist.

What would happen if I didn’t get treated for BV?

In most cases, BV does not cause any long-term problems. It has, however, been linked to other STIs which can cause infections in the cervix, uterus (womb), and fallopian tubes which is called pelvic inflammatory disease (PID). This can lead to infertility. 

How can I prevent myself from getting bacterial vaginosis?

You can reduce your risk of getting BV by:

  • Wiping gently after going to the toilet from front to back, to stop bacteria from getting into the vagina.
  • Using pads instead of tampons when possible. This is because sometimes tampons can change the normal balance of vaginal bacteria.
