In brief: Yeast infection

A yeast infection results from an overgrowth of yeast anywhere in the body.
The growth of yeast is normally limited by our immune system and normal body bacteria. If there is a compromise in our immune system or when taking medications such as antibiotics or steroids, yeast can become so numerous that they cause infections, particularly in warm and moist areas of our body.

In brief: Yeast

Yeast infections are due to a fungus called Candida which is normally found in the vagina.
However, if there is a lack of healthy vaginal bacteria it can lead to overgrowth of yeast. Some causes of overgrowth: antibiotics, ^ estrogen (pregnancy or some birth control pills), malfunctioning immune system, diabetes mellitus as well as friction against vaginal tissues (intercourse) & douching.
