What is bacterial vaginosis (BV)?

Bacterial vaginosis, also called BV is the most common vaginal infection in women of childbearing age. It happens when the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria. The vagina normally contains mostly “good” bacteria, and fewer “harmful” bacteria. BV develops when there is an increase in “harmful” bacteria and fewer “good” bacteria.
