We all have yeasts, the micro-organisms, present in our bodies but in smaller amounts. Sometimes, due to certain medical conditions and even due to certain medicines like antibiotics, the yeast in our body grow to such a level that it leads to infection, mostly in warm and moist body areas. This is known as Yeast Infection whose medical name is Candidiasis. By now you know that it results from the overgrowth of a type of yeast.
This yeast is known as Candida (Candida albicans.) So, our mouths, throat, skin under arms, skin folds like those under breasts or inside elbow or knee area and more commonly genital areas can easily get yeast infection. They all are, however, differentiated with individual names. For example, it is called Thrush when we get it in mouth or throat.
