What is wheat allergy?
Wheat allergy is an adverse reaction to the proteins in wheat. There are different forms of wheat allergy and symptoms will depend on how it presents, for example, whether it affects the gut (classic food allergy) or respiratory system (respiratory allergy or Baker‘s asthma) and can include hives, asthma, hay fever, abdominal cramps, nausea and vomiting.
Wheat allergy is a rare condition, thought to affect less than 1% of the population. The condition can be diagnosed by a skin prick test and a blood test. Wheat allergy is managed by following a wheat free diet.
Coeliac disease and wheat allergy both have very clear criteria for diagnosis (e.g. with blood tests, biopsies) and a body of medical evidence to support them. There are other gluten related conditions, such as non-coeliac gluten sensitivity, which is more difficult to diagnose.
