<<Disclaimer: Verify this information before applying it to your situation.>> I found the following information on a WEB page related to canker sores. "In a small percentage of patients, canker sores occur with gastrointestinal problems, such as an inability to digest certain cereals. In these patients, canker sores appear to be part of a generalized disorder of the digestive tract." Does anyone know if celiacs have more canker sores than others? Any suggestions on how to treat these? Once you're on a g-f diet, is the occurrance of canker sores reduced? Ellen Switkes Oakland, CA
