I have seen 5 patients in the past 2 weeks asking the question: "Do I have a wheat allergy or celiac disease?" Both are immunologic diseases, but they are not the same and they can coexist. Wheat allergy is a classic food allergy caused in this case by the proteins in wheat. Typically, affected patients havesymptoms of the gastrointestinal tract and sometimes with the skin and respiratory tract. Avoiding wheat is the only available therapy and this is very effective.
In both cases, I recommend a diet that avoids at least all wheat products for at least one month plus keeping a very detailed food diary. This should list what the food and drinks were as well as where they came from. Often, patients discover that the cause is not wheat but something else, such as an additive, preservative, food dye, or excipient. Once known, these should be avoided. Balancing good nutrition versus avoiding triggering substances can be difficult. In some cases, I recommend speaking with a certified nutritionist. As part of a healthy lifestyle, I also recommend regular exercise.
If you have questions about wheat allergy or celiac disease, ask your doctor.
