Your immune system tries to remove or isolate the trigger. The result is symptoms such as vomiting or swelling. The most common triggers of anaphylaxis are\u00a0<em>allergens<\/em>. Medicines, foods, insect stings and bites, and latex most often cause severe allergic reactions.<\/p>\n<ul>\n<li><strong>Medicines are the leading cause in adults<\/strong><br \/>Common culprits are penicillin and other antibiotics, aspirin, and aspirin-related products and insulin.<\/li>\n<li><strong>Foods are the leading cause in children<\/strong><br \/>In the U.S., the most common food allergies are peanuts, tree nuts, shellfish, fish, milk, eggs, sesame, soy, and wheat. These are the most common allergens.\u201d In children, the most common food allergies are milk, eggs, peanuts, soy, and wheat. In adults, the most common food allergies are shellfish, tree nuts and peanuts.<\/li>\n<li><strong>Insect stings and bites<\/strong><br \/>Stinging insects such as bees, wasps, hornets, yellow jackets, and fire ants can cause anaphylaxis. Certain tick bites can cause a person to develop severe allergic reactions to meat. Bites from the \u201ckissing bug\u201d and deer fly also cause a local allergic reaction.<\/li>\n<li><a href=\"\/allergies\/types-of-allergies\/latex-allergy\/\"><strong>Latex<\/strong><\/a><br \/>Natural rubber latex may cause a mild skin irritation or it can trigger a severe allergic reaction. Direct contact with latex items (latex gloves, condoms and balloons) can cause a reaction. Inhaling small latex particles that have become airborne can trigger latex allergy. Putting on and removing latex gloves can release small latex particles into the air.<\/li>\n<li><strong>Physical activity<\/strong><br \/>Exercise-induced anaphylaxis is a rare allergic reaction that occurs after vigorous physical activity. Temperature, seasonal changes, drugs, alcohol or eating certain foods before exercise may be co-factors. In other words, both exercise and this other factor have to be present for a person to have the severe allergic reaction.<\/li>\n<\/ul>\n<p>With proper evaluation, allergists identify most causes of anaphylaxis.
