My Mom also had celiac. She was diagnosed back in the 1980's. So when I started having problems I knew. I was in denial for a long time but when my psoriasis got so bad that I couldn't play guitar anymore (I run a music store!) I knew I had better do something. With no insurance I decided to skip testing and just went gluten-free. Like Mom, my psoriasis cleared up. My digestive issues (which were mild) cleared up. My insomnia which had been with me all my life cleared up. Lots of other little problems that I never would have associated with celiac cleared up.
Life is good!
