Everyone always some amount of candida(yeast) in their bodies at all times, and different things can lead to it overtaking and becoming a problem. Hormones, stress, ph levels in the body, and not enough good bacteria to fight it off. In the old days before the over the counter creams women got rid of it douching with vinegar and water mixes. Just to know for future reference, while the over the counter stuff is great, you will get rid of it faster the old fashion way, or if you have a stubborn one it will work when no other will.

While thrush is candida it's a bit different than what you are thinking of as your typical yeast infection. You can have thrush and NOT have a vaginal yeast infection. Babies tend to get it really often especially nursing babies. My oldest did and therefore I ended up with yeast in my nipples that made the skin fall off in sheets... sooo painful and brought breast feeding to an end quick.

Alot of people have an over growth of yeast and don't have a clue about it because of where it set up shop. Someone that has chronic sinus infections or allergies, may actually not have those things but have candida instead. A simple treatment to the body and the days of sinus infections might well be a thing of the past for a handful of lucky folks.

It's a really common thing that most people have effecting them in some way or another, but don't have a clue. I think at the least everyone should just do a candida cleanse at some point just to see what symptoms they can get rid of that they may be contributing to something else. you just never know.
