What is a yeast infection?

Yeast infections are a fungal overgrowth of naturally ocurring yeast organisms on our skin.  While there are more than 20 species of yeast, the most notable series for causing yeast infections is Candida albicans.  There are various types of yeast infections and they may be called by different names depending on who is infected and where the infection occurs.  Vaginal yeast infections, diaper rash, and oral thrush are all yeast infections.
