Yeast infection is caused by a fungus called Candida albicans. You might be surprised to that yeast is found on and in our bodies even in normal conditions. Yeast is present normally even in a healthy vagina along with other bacteria that keep the growth of yeast under control.

When the concentration of yeast in the vaginal area increases more than the normal levels it results in what is commonly called the yeast infection.

Yeast infection is also called candidiasis. The microscopic fungi normally grows on the moist and warm parts of the body like underarms, under the breasts or one might even catch an oral yeast infection. The diaper rash caused in babies is normally due to yeast.

It is also a very common form of vaginal infection. This article describes the yeast infection for women.

A weak immune system, medicines, diabetes or obesity can alter the chemical balance of the vagina thereby allowing the fungus to overgrow which causes intense itching and burning sensation in the vaginal area.
