I went to a Gastroenterologist that found the yeast infestation by performing an colonoscopy and endoscopy while I was under sedation. He found yeast infestation in my throat and lower intestines. He showed me this on the monitor and provided me with pictures. He gave me Difulcan which barely scratched the surface. Finally I agreed to go to a naturpath and he was able to help me through the candida diet, nystatin and hefty doses of probiotics (50 billion count).
