What is BV?
Bacterial Vaginosis (BV) is a vaginal infection caused by an imbalance in the pH levels in your vagina.
It’s the most common vaginal infection and almost twice as common as thrush. It’s also the most common cause of vaginal discharge in women of childbearing age.
For the vagina to remain healthy and free from infection, it is important that the many naturally occurring bacteria that live there remain in perfect balance.
The bacteria usually present in the largest numbers are those which produce lactic acid, helping to maintain the normal low pH of the vagina and protect against infection.
However, if the numbers of lactic acid bacteria are reduced, pH levels rise, encouraging the growth of other bacteria and resulting in embarrassing odour, abnormal vaginal discharge and discomfort.
These unpleasant symptoms all point to BV. Experts estimate that at least one in three women will develop BV at some point in their life.
