Celiac Disease Support Group
Celiac disease is an auto-immune disorder of the digestive system that occurs in genetically-predisposed individuals. It is characterised by damage or flattening to all or part of the villi lining the small intestine, which interferes with the absorption of nutrients. This damage is caused by eating anything with gluten (gliadin), a protein found in wheat, rye, and barley...
Another thing that happened to me when I first went gluten free, was that I felt worse before I felt better. There is a definite withdrawal to the stuff. You may be experiencing that too. Take care and keep us posted on how you are doing.
