Here is a checklist. This doesn't even include the crazy-long list of symptoms for non-celiac gluten intolerance, though since the intestinal biopsy is no longer considered 'the gold standard" and really there is no gold standard, it's even tougher to get any kind of a diagnosis. It is estimated that in the United States 95% OF PEOPLE WHO HAVE CELIAC DISEASE HAVE NOT BEEN DIAGNOSED. Try eating gluten free, you just might feel better and it's not that difficult. If I can do it, anyone can.
