answer type: Risk Factor.
auxiliary information: Bacterial vaginosis, also known as vaginal bacteriosis or Gardnerella vaginitis, is a disease of the vagina caused by excessive bacteria. Common symptoms include increased vaginal discharge that often smells like fish. The discharge is usually white or gray in color. Burning with urination may occur. Itching is uncommon. Occasionally there may be no symptoms. Having BV increases the risk of infection by a number of other sexually transmitted infections including HIV/AIDS. It also increases the risk of early delivery among pregnant women. BV is caused by an imbalance of the naturally occurring bacteria in the vagina. There is a change in the most common type of bacteria and a hundred to thousandfold increase in total numbers of bacteria present. Risk factors include douching, new or multiple sex partners, antibiotics, and using an intrauterine device among others. However, it is not considered a sexually transmitted infection. Diagnosis is suspected based on the symptoms and may be verified by testing the vaginal discharge and finding a higher than normal vaginal pH and large numbers of bacteria. BV is often confused with a vaginal yeast infection or infection with Trichomonas.
