Candida is a type of yeast that is commonly found in the human body along with billions of other micro-organisms. This yeast is present on the skin as well as every mucous membrane in the body including the intestine, stomach, eyes, ears, lungs, vagina, penis etc. The most common strain of this kind of yeast that is found in humans is called Candida Albicans and under normal circumstances it exists in harmony along with other bacteria and fungi in the body. However there are times when there is an immune system dysfunction or an over use of antibiotics. In such a situation, all the microorganisms – good and bad – are wiped out except the resistant Candida. This gives the Candida yeast to proliferate freely and take over the systems of the body resulting in the yeast infection called Candidiasis.
