What Types Of Reactions Do You Get When You're Glutened? in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted March 27, 2008 · Report to Admin i had an endoscopy but it came back negative for celiac. i am chronically constipated and was wondering what types of reactions you had/have when you've been glutened. there are days i can eat pizza and feel fine. (i know i am not suppose to eat it but i generally get a rash on my legs when i do). sometimes i cant keep the craving down, lol! today i had a bag of cadbury mini eggs and felt SO NAUSEOUS about 10 minutes after eating them. now i didn't throw-up but i had a little diahrea. i know - TMI but i am really unsure as to whats wrong with me! i also sometimes feel a weird haze (like i am all foggy) after i had corned beef the other day. i wasnt sure if that was a gluten thing. I also had a negative biopsy, but positive bloodwork. The "gold standard" isn't so gold anymore. Now the most sensitive test for celiac seems to be the tissuetransglutaminase Ttg level in your blood. Mine was three times as much as it should be and an expert in Utah told me that something must have been misread or mistaken in my biopsy. With a level that high, he said I had to have celiac. You probably had the same issue with your biopsy. Sounds like you have more than a gluten sensitivity and if I am not mistaken, the rashes are related to celiac disease not gluten sensitivity.
