Candida overgrowth and an imbalance of gut ecology definitely played a part in my illness. If the same is true for you, an anti-candida diet, meds or supplements will help. Taking probiotics to reestablish the good gut flora will also be beneficial. There are alot of informative books on the subject. My favorite is Candida-Related Complex: What Your Doctor Might Be Missing.http://www.amazon.com/Candida-Related-Complex-Doctor-Might-Missing/dp/0878339353/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1195139485&sr=8-1
In my experience, you can flare again if you get complacent and return to your former bad diet. My GP says he sees alot of folks who return every year or two with yeast problems... it's a cycle for some folks. You get to feeling good for so long, that you start "cheating" again here and there. Because you don't usually have immediate and obvious reactions, you cheat more, but eventually it catches up with you. It's kinda like crash diets for losing weight... it just doesn't work for the long-term. It has to be a commitment to a lifestyle change, not a temporary diet until you're "cured."
