Wheat allergy is a common food allergy impacting individuals across various age groups, from young children to adults. It arises when the body’s immune system, which typically defends against harmful pathogens, mistakenly identifies proteins in wheat as a threat. This misidentification leads to an abnormal immune response characterized by the production of antibodies and the release of histamine and other chemicals. These substances are intended to combat the perceived threat but instead, result in the symptoms of an allergic reaction.

It’s important to note that a wheat allergy is distinct from celiac disease, which is an autoimmune disorder triggered by gluten, and from non-celiac gluten sensitivity, which causes discomfort without the immune system’s involvement.

Understanding Wheat Allergy

A wheat allergy is an immune response to any of the proteins present in wheat, including but not limited to gluten. This response can be triggered not just by ingesting wheat but also, in some cases, by inhaling wheat flour. When a person with a wheat allergy consumes wheat, their immune system identifies wheat proteins as harmful, triggering an allergic reaction. This reaction can occur within minutes to hours after eating wheat. The time frame for the onset of symptoms can be immediate or delayed, adding to the complexity of diagnosing this allergy.

Causes and Risk Factors

While the precise mechanisms triggering wheat allergy aren’t fully understood, it’s known that both hereditary and environmental elements play a role. For example, early exposure to wheat products in infancy has been studied for its potential impact on developing this allergy. Additionally, certain conditions, like the hygiene hypothesis, suggest that a lack of early childhood exposure to infectious agents, symbiotic microorganisms, and parasites increases susceptibility to allergic diseases by suppressing the natural development of the immune system.

Signs of Wheat Allergy

Skin Reactions: Common skin reactions include itching, redness, swelling, and sometimes hives. In severe cases, it can also cause angioedema, a deeper swelling under the skin, often around the eyes and lips. 

Respiratory Symptoms: Wheezing, coughing, nasal congestion, and difficulty breathing are typical respiratory symptoms. These can resemble asthma and, in severe cases, lead to anaphylaxis, a life-threatening reaction that requires immediate medical attention.

Gastrointestinal Issues: In addition to the immediate symptoms, wheat allergy can contribute to long-term gastrointestinal disorders. These include conditions like eosinophilic esophagitis, where eosinophils (a type of white blood cell) build up in the esophagus, leading to inflammation and swallowing difficulties.

Anaphylaxis: Though rare, wheat allergy can cause anaphylaxis. This severe allergic reaction can lead to shock, a rapid drop in blood pressure, and difficulty breathing. It requires immediate medical treatment.

Diagnosis

Along with skin prick and blood tests, an oral food challenge may be conducted in a controlled setting for definitive diagnosis. This is especially useful in cases where the results of the other tests are inconclusive. Furthermore, component-resolved diagnostics, which identify specific allergenic proteins in wheat, are gaining traction as a more precise method for diagnosing wheat allergies.

Management and Treatment

Medications: Antihistamines can help alleviate mild symptoms of wheat allergy. For more severe reactions, such as anaphylaxis, carrying an epinephrine auto-injector is necessary.

Dietary Management: Consulting with a dietitian is beneficial for managing a wheat-free diet. They can offer guidance on suitable food alternatives to ensure that you meet your nutritional needs.

Oral Immunotherapy: At LAFAI, we offer oral immunotherapy (OIT) as a long-term solution for wheat allergy. The goal of this therapy is to raise the individual’s threshold that may trigger a reaction and provide them with protection against accidental ingestion of wheat.
