It’s not just the wheat that takes someone with Celiac disease out it is anything that has gluten in it including a lot of antibiotics. My husband very nearly died as well, caused him to hemorrhage and had to have 6 units of blood. He never i intentionally went off the diet and was well for three years until Melanoma got him. If he by some chance he was exposed to gluten, he was sick for three days without fail.
Interesting. My teenaged son is exactly the same. He has Celiacs and if he gets contaminated with gluten he is out of commission for three days.
I ended up taking two antibiotics for a micro plasma bacterial infection on my lungs. This was followed by some new sickness every week for 6 month’s. When I could not swallow they finally diagnosed it as celiacs. Within three days of not being on gluten I felt like I was on speed I had so much energy. A month later some one I know gave me something that had gluten in it. In twenty minutes I went to sleep and slept for 18 hours. This was after my hands felt like they were on fire and I got cramps. There was maybe a cheese it worth of gluten in what I ate. Now I check everything including my medicine. I won’t eat out either and I don’t eat anything someone has made. I can tell when something has any gluten in it.
