What is recurrent bacterial vaginosis? Recurrent bacterial vaginosis is an imbalance of the vaginal bacteria normally present in the vagina. Bacterial vaginosis is a common condition and treatment is available; however, in some women the condition may recur or even become chronic, requiring multiple and sometimes long-term treatments.
Bacterial vaginosis is a mild infection of the vagina caused by bacteria. Normally, there are a lot of good bacteria and some bad bacteria in the vagina. The good types help control the growth of the bad types. In women with bacterial vaginosis, the balance is upset. There are not enough good bacteria and too many bad bacteria. Bacterial vaginosis is usually a mild problem that may go away on its own in a few days. But it can lead to more serious problems. So it's a good idea to see your doctor and get treatment.
