BV is caused by an imbalance in your vaginal microbiome where the bad bacteria which causes BV outgrows the good bacteria which usually protects your vagina. One of the best ways to treat BV is by not getting it at all. You can help your own vaginal wellness by following the steps here.BV is usually treated by a course of antibiotics which generally clears your infection within a week. In many cases BV returns soon after treatment. This may be because the antibiotics have themselves killed the good bacteria which protect the vagina. You may wish to supplement your vaginal microbiome with Perfect V while you are taking antibiotics and for some time afterwards if you keep getting it back again.
