<<Disclaimer: Verify this information before applying it to your situation.>> Hello all, Thanks for your kind supportive responds to my summary (Absorption) ! Today I had two phonecalls: - the MD who did the gastroscopy stated I was no celiac because the mucous membrane and the villi of the smal intestine were O.K. The Vitamin B 12 absorption problem could lie in the last part of the smal intestine, which is not covered by the gastroscopy. I could X-Ray this part of the smal intestine to see wheter some inflammatory proces is going on. - the contactperson of the german celiac organisation told me that it still is possible that I'm a celiac, cause the Gastroscopy doesn't cover the last part of the small intestine and sometimes there and only there lies the problem. This cannot be checked by some test, also not by endoscopy. The only possibility is to do the GF diet for at least 6 months and see if my condition gets better. So we decided I'll continue GF diet (I started 10 days ago). She interpreted the fact that the flatulence decreased after the GF start as a hint on celiac. Tomorrow I'l visit her and we'll have a more detailed conversation about the whole problem. So maybe I'll know more in 6 months........ And meanwhile I'll maybe let the intestine X-rayed to check the vitamin B 12 problem. When I know more on this puzzle I'll let you know. Best wishes Kareem
