Vaginosis is a very common vaginal condition. The cause is an overgrowth of the bacteria that live normally in the vagina, and it is defined by an increased quantity of certain microbes, altered vaginal acidity, and hence unusual vaginal discharge with itching and a fishy smell. It needs to be distinguished from a yeast infection, where vaginosis generally requires special treatment while antifungal drugs work for yeast infections. Risk factors for vaginosis include vaginal douching, multiple sexual partners, and immune suppression. Maintaining good hygiene with washing and wearing breathable cotton underwear are measures to prevent vaginosis. But if the symptoms continue, the individual should consult a healthcare provider to be examined so treatment for vaginosis can be given.
