No research needed here....I am a living testament that yeast/fungus is/was responsible for my UC symptoms. After going on an antifungal diet (yes, my doctors chuckled, too), along with natural antifungal supplements, I am now, and continue to be symptom-free. A diet change is paramount, along with taking the antifungals. You are still feeding the fungus if you continue to eat grains, sugar, yeast, alcohol. There is much out there to point fungus/yeast as a potential culprit of UC symptoms. If you have ever been on antibiotics, birth control pills, steroids, been exposed to mold, as well as having symptoms of arthritis, yeast infections, psoriasis, diabetes, FM, foggy brain, itchy inner ears, allergies to food or pollen, molds, perfumes, to name a few, then your fungal risk factor could be high.
Bottom line, whether you believe fungus/yeast is the 'cause' of UC symptoms, there are people with UC who, after following an antifungal regimen, have gotten well again. I believe there is a fungus link.
