I gave you a link. Trying not to diagnose you or scare you but - get your liver checked. Get checked for other AI diseases. Chron's? Colitis? I'm sorry. It's highly unlikely you have Celiac. What was the result of your colonoscopy biopsies? That is likely your problem.
Colonoscopy done earlier this year, one small polyp removed, biospsy neg.
Blood test and ultrasound done for liver as part of abdominal US. All normal. No GI doc has even mentioned Chron's or UC. IMO, I may have SIBO, due to previous antiobiotic issues previous to all this starting. I know when I take an antibiotic, things get better. When I take a probiotic, get very bloated. I have told the docs this, in one ear out the other.
