Maybe it's different down here in an area where allergies and environmental sensitivities are almost in fashion these days, but none of the medical professionals I know have failed to see or acknowledge gluten sensitivity and/or celiac disease. In fact, two of the people we know who have celiac disease are physicians themselves; one's a rheumatologist and one an internal medicine doc. Gluten reaction was one of the first things the allergists I've gone to since adolescence ever looked at as a possible cause of my eczema and allergies, which I've had for years. (It wasn't caused by gluten intolerance.) I think it's important for informed people not to assume it's the possible root of all illnesses.
