About Anaphylaxis
What is anaphylaxis?
Anaphylaxis is an acute, severe and potentially life-threatening allergic reaction. It happens when the immune system is exposed to a particular allergen or substance that causes an anaphylactic reaction.
Anaphylaxis is a major medical emergency that affects one or more of the body’s systems (i.e., cardiovascular, respiratory, gastrointestinal, etc.). Anaphylaxis requires immediate treatment.
Causes and triggers
Anaphylaxis happens when an allergen enters the body through inhalation, swallowing, touch or injection.
The most common causes of anaphylaxis are:
- food (especially peanuts, tree nuts, milk, shellfish, fish, eggs, soy, sesame seeds, and wheat)
- insect venom (i.e., wasps, hornets and bees)
- medications
- rubber latex (i.e., rubber gloves, balloons)
- exercise (by being exposed to an allergen during exercise or by exercise alone)
