Causes of egg allergy

If you have an egg allergy, proteins in eggs cause your immune system to overreact (this is what causes an allergic reaction). The proteins that cause egg allergies are mostly in egg whites. If you have an egg allergy, your body creates immunoglobulin E (IgE) after your first exposure to eggs. IgE is an antibody your immune system makes. Your body makes many different types of IgE, which target specific allergens. IgE antibodies bind to mast cells (allergy cells) in your skin, respiratory tract (airways) and cardiovascular system. When they encounter egg proteins, they release histamine. Histamine is what causes your allergy symptoms. IgE reactions happen quickly after you eat eggs. Reactions may include anaphylaxis.
