What is it?
It is called a vaginal yeast or candida infection, but that is a misnomer. What is really happening is an overgrowth of yeast in the vagina. Yeast commonly exists in small amounts in the vagina, it is kept in check by, among other things, the healthy lactobacilli which also live there. So when we have a yeast infection what we have is an overgrowth of this one element. Candida albicans is the most common strain of yeast, though others exist, this is important to remember if you are having a treatment failure: you could have a different strain.
Where does yeast grow?
Anywhere where it is warm and moist is a lovely home for yeast—skin folds anywhere, under breasts and under arms, anywhere around the genitals, inner thighs and buttock where air does not circulate. It can occur in the mouth and digestive tract, typically this is not seen unless you have a weakened immune system.
