After the first sting, the allergic person’s body produces an allergic substance called Immunoglobulin E (IgE) antibody, which reacts with the insect venom. The individual does not usually experience a severe allergic reaction from that first sting—but if he or she is stung again by an insect of the same or similar species, the insect venom interacts with the IgE antibody produced in response to the earlier sting. This triggers the release of histamine and other chemicals that cause allergic symptoms. For a small number of people with severe venom allergy, stings may be life-threatening. Severe allergic reactions to insect stings can involve many body organs and may develop rapidly. This reaction is called anaphylaxis.
