<<Disclaimer: Verify this information before applying it to your situation.>> I am trying to understand why I still experience symptoms (diarrhea, stomach ache, gas/bloating, tired) in spite of my thorough GF diet. I don't appear to be celiac(?), but am gluten intolerant and IgG antigliadin positive. I notice that I don't appear to be digesting my food properly. I can have breakfast at 7:30 am and at 1:00 pm while working out I burp and still taste breakfast! The large volume of stools I produce appear to be peppered with undigested material. This got me to thinking that perhaps it is this indigestion that is the root of my problems. Is it possible that when there is insufficient stomach acid or pancreatic enzymes/bile salts, relatively high concentrations of undigested proteins such as gliadin in the small intestines cause irritation, and eventually sensitization? Is this why so many gluten intolerant people also react to other proteins? I'm going back to the doctor for further follow-up since I'm not getting better and thought I would ask if others have traveled this path already. Has anyone with gluten intolerance also been found to have a problem with digestion (as opposed to absorption)? What caused the indigestion, what was the treatment, and was it of benefit? Thanks for your help. Reimar in Toronto
