Symptoms of Bacterial Vaginosis

Bacterial vaginosis (BV) is not a sexually transmitted infection (STI), but it can increase your risk of getting one. Symptoms include:

An unusual vaginal discharge that has a strong fishy smell, particularly after sex.
A change to the colour and consistency of your discharge, such as becoming greyish-white and thin and watery.

Half of women with BV do not have any symptoms. It does not usually cause any soreness or itching.

Treatment and Prevention

Getting Treatment

BV is usually treated with antibiotic tablets, gels or creams prescribed by a GP or sexual health clinic. It's common for BV to return, and you may require further treatment.

Things You Can Do

Use water and plain soap to wash your genital area.
Do not use perfumed soaps, vaginal deodorants, or douches.
Do not use strong detergents to wash your underwear.
If you are pregnant and notice changes to your vaginal discharge, speak to a GP or midwife, as there is a small chance BV can cause complications.
