<<Disclaimer: Verify this information before applying it to your situation.>> Hello, Our autistic daughter has been gluten free for 12 months. A few weeks ago, we decided to do a gluten challenge and gave her noodles. We did not see any increase in her autistic behaviors; however, her stools immediately started to float, and floated for a week. Two weeks ago she was given a very small amount of bread and, once, again, her stools floated for a couple of days. Last Thursday she was given breaded chicken and, once again, her stools are floating. They are soft and light golden brown, but do not appear to be greasy nor are they noticeably stinky. We are concerned about celiac disease but realize that floating stools, while a symptom, are not axiomatic; floating stools can result merely from change of diet. As I understand it celiac disease results in damage to the villi of the small intestine which decreases its surface area resulting in malabsorption. Shouldn't there be a delay between when gluten is reintroduced into the diet and the villi becoming so damaged that this malabsorption occurs? Thanks Margaret
