The most common symptoms of egg allergy include hives (urticaria) and facial swelling (angioedema) within minutes of exposure, and gastrointestinal symptoms (e.g., stomach pain, nausea, vomiting) within two hours of exposure.[1] More severe symptoms, such as respiratory issues (e.g., cough, wheeze, change in voice pitch or hoarseness, shortness of breath), pale skin, and weakness can also occur, though less commonly. The severity of the reaction can depend on the amount of egg consumed and the degree to which the eggs are processed (raw or cooked, cooking duration and temperature, baked in a recipe with wheat, etc.).[1]
