Egg allergy is a hypersensitivity to proteins in eggs or egg products.

The immune system sees these proteins as a “threat”, and releases antibodies that will diffuse the protein. The antibodies, called immunoglobulin E (IgE), release histamine and other chemicals to fight that protein. These chemicals cause the allergic symptoms.
