Celiac Disease and Gluten Sensitivity
There are no tests or biomarkers for conclusively diagnosing gluten sensitivity, says Alessio Fasano, MD, medical director of the University of Maryland Center for Celiac Research. The condition is typically determined by a positive response to the gluten-free diet. Gluten sensitivity may be up to 6 to 7 times more common than celiac disease, according to Fasano. Unlike celiac disease, gluten sensitivity causes no measurable intestinal damage. Classic symptoms are gastrointestinal discomfort, such as diarrhea, bloating or constipation, but symptoms can range from clumsiness, brain fog and depression to ADHD or autistic behaviors.
