I and every single doctor I have ever been to about this, and I have traveled to specialists in the field would totally disagree.
You are welcome to believe that, but it is not true from a medical perspective.
DH and Celiac disease are classified as Celiac the same way Pneumonia and TB are pulmonary disease. Both have the same root cause but both effect different biological functions in your body. I do not get gas or diarrhea from eating gluten. I only know I am having an attack when i feel an adrenalin surge. One bite of bread no matter how small sets me off.
I have sat though lectures and read about AG4 proteins and antibodies way over my head. You are welcome to do so too, if you think you can understand it.
But, when I bring them to my MD, this is about all I can get out of his explanation.
No, no, no! Dh IS celiac disease! you have been given links to the medical proof of that. The U of Chicago Celiac Disease Center is one of the premier authorities if not the premier authority on celiac disease.
Not all celiacs get GI symptoms. Did you know there is such a thing as silent celiac disease where there are NO symptoms at all? It's true. But those people have villi damage never the less.
