Wheat Allergy: Symptoms, Triggers, and Tips

Wheat allergies can cause a number of different symptoms. According to Cleveland Clinicsymptoms may appear minutes to hours after eating or inhaling wheat, but may take up to two days to appear.

Symptoms that occur shortly after eating or inhaling wheat may include swelling or itching of the mouth or throat, hives, itchy rash, headache, breathing problems, nasal congestion, diarrhea, cramps, nausea or vomiting (via Mayo Clinic). Some people can also suffer from anaphylaxis. This reaction has its own set of symptoms that indicate a life-threatening situation. These symptoms include tightness in the throat, chest pain, difficulty breathing, difficulty swallowing, dizziness, fainting, and pale or blue skin. Anaphylaxis can occur shortly after exposure to wheat. In some people, this can only happen if they exercise a few hours after eating wheat. The Mayo Clinic calls this wheat-dependent, exercise-induced anaphylaxis.

According to ACAAI, certain wheat allergy symptoms like stomach cramps, diarrhea, and gastrointestinal discomfort are also signs of celiac disease. It is therefore important to make the correct diagnosis.
