People with a wheat allergy have an irregular immune system response to at least one of the proteins in wheat. If a person with a wheat allergy has exposure to it, they may experience debilitating symptoms. In some cases, anaphylaxis can occur. This is a life threatening allergic response. People who suspect that they may have a wheat allergy should seek immediate medical attention to confirm the diagnosis. Some people experience an allergic reaction when they inhale wheat flour. Others experience symptoms after consuming it orally. An allergic reaction may occur within minutes or hours of either consuming or inhaling wheat. A wheat allergy is one of the most common childhood food allergies. However, it can also occur in adults. A person with a wheat allergy has developed a specific antibody to one or several wheat proteins. Wheat allergy is not the same as celiac disease. Celiac disease is an autoimmune condition that affects a person’s digestive tract. Gluten can still trigger an irregular autoimmune response, but the medical management tips and nutrition guidelines are different for people with celiac disease. Also, although gluten is a protein in wheat, people with celiac disease will not experience anaphylaxis. This is because celiac disease is not a type of allergic reaction. This article covers how to recognize a wheat allergy, what triggers it, and some foods to avoid that contain wheat. Wheat allergies tend to develop in infancy, often alongside other food allergies. It will usually resolve by the time a person is 12 years of age. Although some adults have a wheat allergy, it is far more common in children. The most common symptoms of a wheat allergy include:
Anaphylaxis may also occur, leading to:
Anaphylaxis is a medical emergency that requires immediate medical attention. People need to visit a medical professional for treatment. Several strategies, including some tests, can help a doctor identify a wheat allergy. These include:
People with a wheat allergy should avoid food that contains wheat, including:
Barley, oats, and rye also contain some wheat proteins. A person with a wheat allergy may be allergic not just to wheat, but also to rye, oats, and barley. Before consuming wheat, it is good practice to check the nutrition label of each food to see if it contains wheat or any other grains that have wheat proteins. The manufacturer may have processed certain foods in a facility that also processes wheat. A wheat allergy is an immune system response. An allergic reaction occurs when the immune system mistakes a neutral or beneficial substance for a pathogen and attacks it. Allergens are substances that cause no harm to most people, unless they have an allergy to it. An allergic reaction to wheat involves immunoglobulin antibodies reacting to at least one of the following proteins in wheat:
Some people are allergic to just one of the proteins in wheat, while others may be allergic to two or more. The sections below list some of the known triggers of a reaction to wheat. Wheat and exerciseSome people may have allergic symptoms if they exercise within a few hours of consuming wheat proteins. This type of allergic reaction often leads to life threatening anaphylaxis. Baker’s asthmaPeople who work in bakeries or places with uncooked wheat flour may develop baker’s asthma. The allergy occurs due to wheat flour inhalation, not ingestion. It tends to affect breathing, and it may occur due to a wheat protein or a fungus. Celiac diseaseMedical experts class celiac disease as an autoimmune food sensitivity, rather than an allergy. The immune system reacts to gluten, causing inflammation and damage in the small intestine. This leads to poor absorption of nutrients. Some people have both celiac disease and a wheat allergy.

If a close relative has an allergy — such as a wheat allergy, hay fever, or asthma — there is a higher risk that a person will develop a wheat allergy themselves. Infants and young children are more likely to have a wheat allergy than older adults because their immune and digestive systems have not yet matured. Most children eventually outgrow this allergy, however. The best treatment for a wheat allergy is to avoid wheat proteins. This can be difficult, as so many foods contain wheat. It is therefore important to check food labels. Antihistamines can lower an individual’s immune activity, eliminating or reducing the symptoms of allergy. People should take these after exposure to wheat. Also, people should only use antihistamines under the guidance of a physician. Epinephrine, or adrenaline, is an emergency treatment for anaphylaxis. People with a high risk of anaphylaxis should carry two injectable doses of epinephrine. Adrenaline opens the airways, helping an individual breathe more easily. It also helps restore severely low blood pressure. A person can administer the medication through an auto-injector pen straight into the skin. One pen contains a single dose of adrenaline, which a person can inject using a concealed, spring-loaded needle. Examples include the EpiPen and the Anapen.
