What causes the yeast to overgrow?
There are several common causes yeast infections. One is antibiotic treatment. Because antibiotics kill bacteria, they may destroy normal acid-producing bacteria in the vagina, which makes it easier for the yeast to grow. Other conditions such as pregnancy and diabetes change the chemical environment and make it easier for yeast to grow. In some women birth control pill use may be associated with increased yeast infections. Yeast likes to grow in moist places, so, if the skin of the external genitals is not allowed to dry, this may promote yeast growth.
