Bacterial vaginosis (BV) is caused by an overgrowth of bugs (bacteria) that are normally found in the vagina in small numbers. It is not passed on during sex.
BV may cause an increase in discharge from the vagina, or an unusual smell.
You can be tested for BV with a vaginal swab.
If BV is causing symptoms, it is treated with antibiotics.
If you have any vaginal symptoms, it is important to get checked in case you have a sexually transmitted disease (STI). You can go to your general practice team, Sexual Health Clinic or Sexual Wellbeing Aotearoa Clinic
