Modern medicine clearly diagnoses the symptoms that appear after consuming wheat flour as a 'wheat allergy.' A wheat allergy is an excessive immune response of our body to specific proteins contained in wheat, such as gluten, albumin, and globulin, operating through a mechanism completely different from simple indigestion or gluten sensitivity.
Most wheat allergies are classified as IgE-mediated allergies. The body recognizes wheat proteins as harmful invaders and produces a specific antibody called immunoglobulin E to counter them. These IgE antibodies attach to the surface of immune cells called mast cells; upon re-exposure to wheat proteins, they activate the mast cells to rapidly release histamine and other inflammatory mediators. These released substances dilate blood vessels, stimulate nerves, and provoke diverse symptoms.
Symptoms vary greatly depending on the individual, the amount of wheat ingested, and the severity of the allergic reaction. Skin manifestations include urticaria, pruritus, and angioedema, while the digestive system may experience abdominal pain, vomiting, and diarrhea. Respiratory system symptoms range from nasal congestion, a runny nose, and sneezing to cough, wheezing, and dyspnea caused by bronchospasm. The most critical scenario is anaphylaxis, a severe allergic reaction simultaneously involving multiple organs that can lead to a drop in blood pressure, loss of consciousness, and shock, creating a life-threatening emergency.
While wheat allergies are more common in infants and young children than in adults, they can develop suddenly in adulthood as well. There are also distinct forms, such as wheat-dependent exercise-induced anaphylaxis, where symptoms manifest only under specific conditions like exercise following wheat intake, requiring caution.
Consulting an allergy specialist is essential for diagnosis. Specific IgE antibody levels against wheat proteins are measured via a skin prick test or blood test. When necessary for an accurate diagnosis, an oral food challenge may be conducted. While this test is the most accurate diagnostic method—confirming actual reactions by having the patient ingest small amounts of wheat under medical supervision—it carries risks and must only be performed under thorough preparation and observation.
The most definitive management for a wheat allergy is wheat avoidance. It is crucial to eliminate all wheat-containing foods, carefully inspect food labels, and consider the possibility of cross-contamination. Furthermore, it is vital to be prescribed and always carry an epinephrine auto-injector in preparation for potential anaphylaxis, ensuring you understand how to use it. Do not forget to establish your own emergency action plan. By recognizing and managing your body’s critical signals, you can reclaim a healthy and safe daily life.
