<<Disclaimer: Verify this information before applying it to your situation.>> Hi Everyone, I recently had a six month checkup with my GI doctor and we discussed the results of my children's blood tests for Celiac. I asked him about the false positives on the antigliadin IgG blood tests (all my children were negative on everything else). He reassured me that these tests are indicative of them coming into contact with something in the past and are not predictive of them necessarily being more susceptible to developing Celiac in the future. He also cautioned me about being too overzealous in testing children as you don't want to make them feel as though they are sick. I brought up one of the reasons why I had the tests done and this was because my middle child was somewhat irritable and I had heard this can be a sign of Celiac in children. He said this is only if the children have symptoms ( I am assuming he means digestive symptoms). So this is one of my questions, for the parents who have biopsy diagnosed Celiac children, were these children's main complaints digestive in nature and the irritability was a side effect or is it possible for a child with Celiac to have as a major complaint, irritability and bad behavior? My second question is about the small intestinal lymphoma. Can a biopsy proven Celiac who does not have the typical digestive symptoms still be in danger of contracting lymphoma or is it only a danger in those with the typical digestive symptoms? My GI doctor felt it was only those Celiacs who had symptoms who were vulnerable to this kind of cancer. I am again assuming he means digestive symptoms. If anyone has any documentation or studies done on this, let me know and I can show him the next time I see him. My last question is regarding intestinal gas. My doctor recommended taking activated charcoal to prevent gas and I was wondering if anyone knew anything about this. I guess I was wondering if it might be a carcinogen? Thanks for any input you might have, Barb from NE Ohio
