Wheat Allergy

A wheat allergy is an immune system reaction to one of the proteins in wheat, which is a common ingredient in many foods. This type of allergy is most common in children and often resolves on its own by adulthood.

Symptoms

• Hives or itchy skin
• Stomach cramps
• Diarrhea
• Vomiting
• Bloody stools
• Runny nose
• Conjunctivitis (pink eye)
• Asthma-like symptoms, such as wheezing and coughing
• Anaphylaxis, a severe, life-threatening allergic reaction

Causes

A wheat allergy occurs when the immune system mistakenly identifies one of the proteins in wheat (such as gliadin or gluten) as harmful. The immune system then produces antibodies to fight the protein, which can cause the release of chemical mediators and lead to allergic symptoms.

Risk Factors

• Family history: Having a family history of allergies or asthma increases the risk of developing a wheat allergy
• Other allergies: Having other allergies, such as eczema or hay fever, increases the risk of developing a wheat allergy
• Age: Wheat allergy is most common in children under the age of 3

Diagnosis

A wheat allergy can be diagnosed through:

• Skin prick test (SPT): A small amount of wheat extract is placed on the skin, and the skin is pricked with a needle to observe the reaction
• Blood tests: Measuring the levels of immunoglobulin E (IgE) antibodies in the blood can help diagnose a wheat allergy
• Elimination diet: Removing wheat from the diet for a period of time and monitoring symptoms can help determine if a wheat allergy is present

Treatment

The primary treatment for a wheat allergy is to avoid consuming wheat and wheat products. This can be challenging, as wheat is a common ingredient in many foods.

• Reading food labels carefully: Checking the ingredient list for wheat, wheat flour, or other wheat-derived ingredients
• Avoiding cross-contamination: Taking steps to avoid cross-contamination with wheat in food preparation and storage
• Using alternative grains: Substituting wheat with other grains, such as rice, corn, or quinoa, can help manage a wheat allergy
• Medications: Antihistamines or epinephrine injectors may be prescribed to treat severe allergic reactions

Prevention

While it is not possible to prevent a wheat allergy, taking steps to avoid exposure to wheat and wheat products can help manage the condition.

• Breastfeeding: Exclusive breastfeeding for at least 4-6 months may reduce the risk of developing a wheat allergy
• Introduction of solid foods: Introducing solid foods, including wheat, in a gradual and controlled manner may help reduce the risk of developing an allergy
