wabillin replied to at1992's topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsIt is unusual to have such a delay in symtpom onset following gluten ingestion, a hours to a couple days is much more typical. It sounds like whoever did your scopes what not thorough enough and you should try to get another endoscopy and colonoscopy with biopsies of at least your small and large intestines to difinitely check for Celiacs, IBD, etc. It is certainly possible to have negative blood tests and positive biopsies with Celiacs disease, particularly if you have an IgA deficiency (associated with Celiacs). Bleeding is also somewhat unusual for Celiacs disease and is certainly more associated with IBD, but alone doesn't help terribly much with diagnosis. I would definitely recommend you see a new GI who is more well versed or specializes in Celiacs and or IBD to get those biopsies. In the meantime stick with a gluten free diet as best as possible. Good luck!
