Many women will experience some type of vaginal infection in their lifetime. Vaginal infection may be recognized by an abnormal and sometimes foul smelling discharge. However, not all vaginal discharge represents infection. Noninfectious causes of vaginal discharge include allergic reactions and irritations to soaps, douches, or spermicidal products. The vagina normally produces a discharge as a cleansing mechanism.
Vaginal secretions maintain a normal, healthy vagina.
The healthy vagina contains a variety of bacteria, some which are potentially harmful if they are present in excess. One of the most important is called Lactobacillus, a good bacteria that keeps the vagina acidic to help reduce the growth of potentially harmful bacteria. The transfer of infectious organisms during intercourse may also cause vaginal infections. Your doctor can diagnose vaginal infections by evaluating the color, consistency, and acidity of the discharge and by analyzing the discharge under the microscope. It has been shown that BV occurs more frequently in women who have new sexual partners, and multiple partners.
