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. webmd medical reference from healthwise this information is not intended to replace the advice of a doctor. healthwise disclaims any liability for the decisions you make based on this information. © 1995-2011 healthwise incorporated. healthwise healthwise for every health decision and the healthwise logo are trademarks of healthwise incorporated.
