<<Disclaimer: Verify this information before applying it to your situation.>> Hi... I have had Celiac for several years, and was diagnosed March of 97. I did gain weight and have felt better, but have had periods of complete exhastion and terrible headaches,along with on off stomach distress. The docs seem to be happy about weight gain, but I still do not feel that great. Could someone tell me what to look for with regard to intestinal yeast problems. I am having another biopsy in a few weeks. Can they test then??? Thanks for the help! Cindy in the BayArea
