Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Alcohol can certainly irritate an inflamed, damaged gut.  Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal.    

The past symptoms you posted in the thread below are definitely worrisome, and could be celiac disease symptoms. I agree that a full blood panel needs to be done. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.    

Celiac disease does not damage the stomach. It damages the lining of the small bowel, the part of the intestines immediately below the stomach. Also called the duodenum. Do you know if biopsies were taken from this are to look for celiac disease?

Do you mean your tTg-IgA levels? Do you happen to have the reference range for a positive test if that is the case?

@knitty kitty no genetic tests, live in the midlands UK and google didn't even throw up any options for that other than they cost a "few hundred dollars".   They did the endoscopy, the results were that my stomach was completely normal , no signs of inflammation or anything abnormal whatsoever. Hence I felt that ruled out celiac , I've been tested twice in my life , once in 2022 when my levels were 0.3, this time just they were 0.2
