What Is Anaphylaxis?
Reviewed: Dr. Gromatzky
2. Causes of Anaphylaxis
Anaphylaxis can result from exposure to any substance to which a person is allergic. The most common triggers are venom from an insect bite, certain foods, and certain chemical compounds in medications. Foods are the more common triggers in children. Other causes of anaphylaxis include semen, food colors and additives, and topical medications.
Physical factors like heavy exercises and extremes of temperature can also trigger anaphylaxis in some people. In some cases, called idiopathic anaphylaxis, the cause is unknown. It is also feared that some vaccines can lead to anaphylaxis. For this reason, it is prudent to test vaccines before use, especially in people with known allergies.
