Thanks for the reply, I will ask for the antibody test. FODMAP does not eliminate gluten so it shouldn’t affect the results.

I would ask to have celiac antibody blood tests done. These tests would not be valid, however, unless you were eating normal amounts of gluten for weeks or months leading up to the blood draw. So, not sure how the FODMAP diet figures into that. Ask for a minimum of 1. total IGA and 2. TTG-IGA. "Villi are swollen, congested, and shorter." "Moderate chronic duodenitis with loss of villi." These two lab findings you list are classic signs of celiac disease but can also have other causes.

I never said anesthesia. Medical companies can of course change their ingredients at anytime. What may be listed as gluten free on a website may not be updated so always good to check with pharmacy or the medical company itself. 

So there can be gluten in pain meds, but I've never heard of it in anesthesia before. Do you have any more info on this claim, perhaps a link to a source?

The only thing that was visually seen was oesophagitis. The rest of the results are from biopsies. The blood vessels were from the small intestine
