I haven't personally had any experiences with yeast and HS, but I came across this site a while back and remembered people believing that HS was linked to overproduction of yeast.

"10/03/2010: Andrea from Lahaina, Hi replies: "I have had HS for almost 20 years. I have outbreaks under my armpits, breasts and between my thighs. I started taking AZO Yeast Supplements about two years ago because I started getting Thrush on my tongue. I thought it was due to Wellbutrin, which I was taking at the time. Miracles beyond miracles my HS started to clear up. I was taking one pill a day for the thrush and now I take two pills daily without fail. If I forget a day I immediately get a breakout, then I take 4 pills, then almost overnight I start to heal. I just ordered 10 boxes of Azo Yeast pills on Vitacost.com. They are inexpensive and I will take them the rest of my life. I am convinced that HS is related to an overproduction of yeast."
