An egg allergy is caused by the immune system overreacting to the egg.
An adverse reaction to a food, not caused by the immune system, is called food intolerance. Some patients develop stomach acidity or reflux after consuming certain foods like eggs. These are symptoms of food intolerance and not food allergy.
Egg allergy is managed by strict avoidance of eggs and keeping injectable epinephrine and antihistamine available on hand for accidental exposure.
Avoid all foods that contain egg, and please see a board certified allergist or immunologist as soon as possible.
