An allergen is a substance that is harmless to most people, unless they have an allergy to it. An allergic reaction to wheat involves IgE (immunoglobulin) antibodies reacting to at least one of the following proteins found in wheat:
Most allergic reactions involve albumin and globulin. Allergy to gliadin and gluten are less common. Gluten allergy is often confused with celiac disease and other digestive disorders.
Some people have an allergic reaction when they inhale wheat flour, while in others, eat it triggers symptoms. An allergic reaction can occur within minutes or sometimes hours of either consuming or inhaling wheat.
Wheat allergy is very common. Please discuss with your doctor for further information.
The common symptoms of wheat allergy are:
Anaphylaxis may occur, leading to:
Anaphylaxis is a medical emergency.
There may be some symptoms not listed above. If you have any concerns about a symptom, please consult your doctor.
If you have any signs or symptoms listed above or have any questions, please consult with your doctor. Everyone’s body acts differently. It is always best to discuss with your doctor what is best for your situation.
If you have wheat allergy, exposure to a wheat protein primes your immune system for an allergic reaction. You can develop an allergy to any of the four classes of wheat proteins — albumin, globulin, gliadin and gluten.
Sources of wheat proteins
Some sources of wheat proteins are obvious, such as bread, but all wheat proteins — and gluten in particular — can be found in many prepared foods and even in some cosmetics, bath products and play dough. Foods that may include wheat proteins include:
If you have a wheat allergy, you might also be allergic to barley, oats and rye — but the chance is slim. If you’re not allergic to grains other than wheat, a wheat-free diet is less restrictive than a gluten-free diet.
Wheat-dependent, exercise-induced anaphylaxis
Some people with a wheat allergy develop symptoms only if they exercise within a few hours after eating wheat. Exercise-induced changes in your body either trigger an allergic reaction or worsen an immune system response to a wheat protein. This condition usually results in life-threatening anaphylaxis.
There are many risk factors for wheat allergy, such as:

It is important to get an accurate diagnosis of wheat allergy, so that you can avoid appropriate foods and rule out other conditions such as celiac disease. An allergist will typically diagnose a wheat allergy.
To diagnose a wheat allergy, your allergist will ask you questions about your symptoms and family history to determine whether or not allergies are common in your bloodline.
Because the symptoms of a wheat allergy can overlap with the symptoms of celiac disease and non-celiac gluten sensitivity, your doctor will perform specific diagnostic tests to rule out these conditions and determine that you have wheat allergy. The diagnostic test will either be a skin-prick test, a blood test, or both.
In a skin-prick test, your doctor will inject a small amount of purified wheat protein under the surface of your skin, usually on your forearm or upper back. If the injection site becomes red or swollen, a wheat allergy will be confirmed.
Wheat allergy can also be diagnosed through a blood test. Your doctor will draw a small sample of your blood and test for the specific antibodies that have developed against wheat in your immune system. There is a different blood test that can test specifically for celiac disease.
The best treatment is to avoid wheat proteins, but this can be difficult, as so many foods contain wheat. It is important to check food labels.
Antihistamines lower the patient’s immune system, eliminating or reducing the symptoms of allergy. These should be taken after exposure to wheat. Antihistamine should be used under the guidance of a physician.
Epinephrine, or adrenaline, is an emergency treatment for anaphylaxis. Patients at high risk of anaphylaxis should carry two injectable doses of epinephrine. The medication is administered as an auto-injector pen straight onto the skin.
One pen contains a single dose of adrenaline, which can be injected into the body through a concealed spring-loaded needle. Examples include the EpiPen and the Anapen. Adrenaline opens the airways, helping the patient to breathe more easily. It also helps to restore severely low blood pressure.
The following lifestyles and home remedies might help you cope with wheat allergy:
If you have any questions, please consult with your doctor to better understand the best solution for you.
