Allergy of wheat: understanding symptoms, diagnosis, and management

Wheat is a staple food in many cultures and is found in various forms such as bread, pasta, cereals, and baked goods.

While it provides essential nutrients and carbohydrates, for some individuals, wheat can trigger allergic reactions. Wheat allergy is a common food allergy, especially among children, and can cause a range of symptoms from mild to severe. Understanding the symptoms, diagnosis, and management of wheat allergy is crucial for affected individuals and their caregivers.
Allergy of wheat: understanding symptoms, diagnosis, and management


Wheat allergy symptoms can vary widely among individuals and may include:

Skin reactions:

Skin reactions are common in wheat allergy and may manifest as hives, eczema, or dermatitis. These reactions typically occur shortly after consuming wheat-containing foods or coming into contact with wheat.

Respiratory symptoms:

Respiratory symptoms may include nasal congestion, runny nose, sneezing, wheezing, coughing, or difficulty breathing. In severe cases, wheat allergy can lead to anaphylaxis, a life-threatening allergic reaction characterized by swelling of the throat, rapid pulse, drop in blood pressure, and loss of consciousness.

Gastrointestinal distress:

Gastrointestinal symptoms such as abdominal pain, cramps, diarrhea, nausea, or vomiting may occur after ingesting wheat.


Diagnosing wheat allergy involves a combination of medical history, physical examination, and diagnostic tests. Your doctor may perform the following:

Medical history:

Your doctor will ask about your symptoms, including when they occur and their severity. Be prepared to provide details about your diet and any recent exposure to wheat-containing foods.

Skin prick test:

A skin prick test involves placing a small amount of wheat protein extract on the skin and then pricking the skin to allow the extract to enter. If you’re allergic to wheat, you may develop a raised, red bump at the site of the prick within 15-20 minutes.

Blood tests:

Blood tests measure the levels of specific antibodies, such as immunoglobulin E (IgE), produced in response to wheat proteins. Elevated levels of these antibodies may indicate an allergy.

Oral food challenge:

In some cases, your doctor may recommend an oral food challenge, where you consume increasing amounts of wheat under medical supervision to monitor for allergic reactions.


Managing wheat allergy involves strict avoidance of wheat-containing foods and preparedness for allergic reactions. Here are some tips for managing wheat allergy:

Read food labels:

Carefully read food labels to identify wheat and its derivatives, such as wheat flour, wheat germ, wheat starch, and semolina. Be aware of hidden sources of wheat in processed foods and sauces.

Substitute wheat:

Explore alternative grains and flours such as rice, oats, corn, quinoa, and almond flour for baking and cooking.

Inform others:

Inform family members, friends, caregivers, and restaurant staff about your wheat allergy to avoid accidental exposure. Emphasize the importance of cross-contamination prevention.

Carry medication:

Carry an epinephrine auto-injector (e.g., EpiPen) at all times, especially if you have a history of severe allergic reactions. Learn how to use it and make sure it’s not expired.
