I just wanted to say that I was diagnosed with an auto-immune disease (fibromyalgia) a little over 20 yrs ago. I went on a gluten free diet and within 36 hours of going gluten free I would say 85% of all my major symptoms, one being severe all over body pain, had disappeared! So to answer your question, yes, I do believe that some disease can be helped with taking gluten out of your diet.
All you can do is to try it and give it time. I really hope that going gluten free can bring relief to you and possibly cure your disease!
