Bacterial vaginosis is a common infection that occurs in the vagina and can lead to a foul-smelling vaginal discharge. Vaginal discharge is a term used by healthcare professionals to describe any fluid that comes out of the vagina. While some amount of vaginal discharge is normal, those with bacterial vaginosis may experience a significant amount of discharge or discharge that has an unpleasant odor. This infection is caused by certain bacteria that can change the types and amounts of bacteria normally found in the vagina. Bacterial vaginosis is more common in people who are sexually active, especially those with new or multiple partners. Those with bacterial vaginosis are also at a higher risk of contracting other sexually transmitted infections. Symptoms of bacterial vaginosis may include a fishy-smelling vaginal discharge that is watery and off-white or gray, particularly during menstruation or after sex with a male partner. Some people may also experience a burning sensation in the vagina.
