technically while there is an underlying inflammatory condition, it isn't necessarily yeast. It can be a number of things.
It was a big thing in naturopathic medicine to blame all ailments on candida. What I tell people to remember is that if you have an overgrowth of candida (which can happen, but much less often than people think!) it's a symptom of a bigger issue. The candida is basically opportunistic and it won't thrive if everything else is in balance.
