Yes, checked for Celiac, two endoscopys and two colonoscopys...fun, fun, no inflammation, no blood in stool (visible or otherwise, did samples of that too.) I don't believe i have any outright food allergies , but I avoid dairy and TRY to limit gluten (not going to lie and say I do too well avoiding gluten it's in effing everything almost and I have just as much trouble with gluten free junk because of all the preservatives in it.)
