Causes of recurring bacterial vaginal infections

Bacterial infections are common, and their effects vary. There are a number of different bacteria that can cause illness, and you can become exposed to them in a variety of ways. Bacteria are small organisms that can invade the body, causing illness. These infections usually trigger a protective immune response. You also have innate bacteria in your body that helps digest your food and protect your body from harmful bacteria. Children and adults of any age can develop a bacterial infection.

A yeast infection is a very common infection of the vagina that affects most women at some time in their lives, sometimes recurring over time, according to MayoClinic. Also called vaginitis and candidiasis, a yeast infection develops when the fungal microorganism candida becomes too prolific in your body. While it's not the only contributing factor in the development of yeast infections, the amount of sugar in your diet can play a role. Normally, candida — a type of yeast — exists in your vaginal canal with no problem; your body's natural healthy bacteria keep it in check. Occasionally, however, changes in your body's bacterial balance can stimulate the overgrowth of candida and develop into a yeast infection. Although generally not harmful, yeast infection symptoms can be unpleasant and annoying. Symptoms generally include inflammation of the vulva and vaginal opening; itchiness, pain and burning sensations; pain upon sexual intercourse; and creamy, white vaginal discharge, according to the College of Charleston Student Health 1.
