Egg allergy

Eggs in themselves aren't bad, but when you're allergic to them, your body thinks they are. When a person is allergic to eggs, the body's immune system overreacts to proteins in the egg. Every time something made with eggs enters the digestive system of a person with an egg allergy, the body thinks that these proteins are harmful invaders. The immune system responds by creating specific antibodies to that food, which are designed to fight off the “invader.” These antibodies — called immunoglobulin E (IgE) — trigger the release of certain chemicals into the body, one of which is histamine. So when a person with an egg allergy eats a food that contains eggs, the immune system unleashes an army of chemicals to protect the body. The release of these chemicals can affect the respiratory system, gastrointestinal tract, skin, and the cardiovascular system — causing allergy symptoms like wheezing, nausea, headache, stomachache, and itchy hives. Egg allergy is like most food allergy reactions: It usually happens within minutes to hours after eating eggs. Most reactions last less than a day and may affect any of three body systems: the skin - in the form of red, bumpy rashes (hives), eczema, or redness and swelling around the mouth the gastrointestinal tract - in the form of belly cramps, diarrhea, nausea, or vomiting the respiratory tract - symptoms can range from a runny nose, itchy, watery eyes, and sneezing to the triggering of asthma with coughing and wheezing Source: http://69.7.225.164/teen/food_fitness/nutrition/egg_allergy.html
