General Information

Eggs are one of the most allergic products in children and adults.

Symptoms of anaphylaxis are: constriction of airways due to swelling, abdominal pain, increased pulse, shock - sharp decrease in blood pressure, blurring of consciousness.


An inadequate reaction of the immune system is the basis of all allergies. In case of egg allergy, the proteins in its composition are perceived as dangerous for the body. Immune system cells (antibodies) detect antigens (proteins), send a signal to the immune system that causes the release of histamine and other mediators, resulting in the development of symptoms.

Egg yolk and egg white both cause allergies, but the more sensitizing protein. Breastfed babies may also develop allergies when their mothers eat egg products.
