When Is Diarrhea Just Diarrhea? in Parents, Friends and Loved Ones of Celiacs Posted June 19, 2008 · Report to Admin I look for the other symptoms before sayng my daughter has been glutened. Changes in mood, disposition, hunger, sleep habits, pee habits, etc. along with the diarrhea usually indicate she has been glutened. Finding the source is always fun. The cat food could easily be a problem. Then again, crumbs on the table, floor, etc cause problems too.
