I was diagnosed Celiac in 2001. If I eat/drink anything with gluten, IF I don't get sick shortly afterword, the gluten destroys your immune system making you wide open for all kinds of diseases, cancers etc. So it's a bit more than an affliction for me. Had a colonoscopy and endoscopy earlier this year, and the Doc said that while I still have celiac, it is inactive, and that's all thanks to controlling my diet.
So, nothing with wheat, oats, barley or rye. Some forms of oats seem to be OK. Cheerios have a honey nut cereal that's OK. I get it at Costco, so not too expensive. No beer, bread, pasta etc., but that's OK, because I'm still healthy. My Mom passed away at 61 with cancer. That was 35+ years ago but I believe she had what I have, but was never diagnosed. Since my discovery, several others in my family have been diagnosed with it too, so it's hereditary.
There's no medication or cure for this, just control of diet.
