Bacterial vaginosis is a condition of the vagina which is associated with overgrowth or an imbalance of the bacteria that occurs naturally within the walls of the vagina. Women with bacterial vaginosis do not complain of any itching or swelling; however, the condition is associated with an off-white or yellowish vaginal discharge.

The symptoms of bacterial vaginosis include a vaginal discharge, which varies between off-white, yellow and yellowish-brown, and has an unpleasant fishy odor. Women, who develop the condition, complain of an increase in the abnormal discharge especially after sexual intercourse. Other symptoms of bacterial vaginosis are burning sensation during urination, painful intercourse, itching in the vaginal area, or light bleeding.

Though bacterial vaginosis is not a sexually transmitted disease, it however occurs more in women who are sexually active. The condition itself is not severe and may go away in a few days without medical attention, but it may lead to more severe problems like some forms of sexually transmitted diseases.
