Bacterial Vaginosis (BV)

Bacterial vaginosis (BV) is not a sexually transmitted infection, but it can cause an increase in unpleasant smelling vaginal discharge.

What is it and how do I get it?

Bacterial vaginosis (or BV for short) is not a sexually transmitted infection, but it is the most common cause of abnormal vaginal discharge in people with a vagina of childbearing age.

You cannot catch BV but it can increase your risk of getting an STI such as chlamydia.

BV is caused by a change in the natural balance of bacteria in your vagina.

BV can be triggered by using scented bubble bath, shower gel or soaps, using vaginal deodorant or putting antiseptic liquids in the bath. Semen in the vagina after unprotected sex and hormone changes during the menstrual cycle might also play a part. Smokers are also more likely to get BV.

How do I test for it?

BV is diagnosed at the sexual health clinic by looking at a sample of vaginal discharge under the microscope.

How do I get treatment?

BV may settle down on its own or vary through the monthly cycle, but it can be treated with antibiotics. This is commonly given as a course of tablets taken by mouth, but it can sometimes be given as a gel or a cream to use inside the vagina.

Should I tell the people I have sex with?
