We went over this in my summer course today. We learned that gluten intolerance can also cause skin problems- like rashes, eczema and hives. My instructor said that some people experience defects in their teeth or may have problems with memory, like poor short-term memory or difficulty paying attention.
These symptoms are actually all very surprising to me because I didn't know that this was an immune disease. I thought it was food allergies and only caused digestive problems. I would have never thought that it could affect mood or memory.
