Answer to Question 1
Non-celiac gluten sensitivity, or gluten sensitivity, is a reaction to gluten that results in symptoms that are similar to wheat allergy or celiac disease. The important difference is that gluten sensitivity does not involve allergic or autoimmune mechanisms. Gluten sensitivity can be suspected if blood tests for wheat allergy and celiac disease are negative and symptoms of intolerance resolve with a gluten-free diet. The diagnosis may be substantiated if a subsequent challenge of reintroducing gluten in the diet results in a return of symptoms.
