Causes of anaphylaxis

Anaphylaxis can be caused by a number of allergens, which trigger this serious and extreme reaction.

The most common (and rare) causes of anaphylaxis are:


Certain foods are most common and major triggers of anaphylaxis (especially peanuts). Many more children these days have a serious reaction to peanuts, which can end up in a serious anaphylactic reaction.


Surprisingly, exercise is a little known cause of anaphylaxis and that is most likely due to it triggering a severe asthma attack that develops in a serious anaphylactic reaction. This is a less common cause of anaphylaxis and usually only occurs when food is eaten and then exercises 3-4 hours after eating it.

Insect bites

Insect bites are another common cause of anaphylaxis. The site of the insect bite is the first point of swelling and symptoms often can get worse from there. The insects that most commonly cause anaphylaxis in people susceptible are: bees and wasps.



Contact with latex (which was originally made from the sap that comes from the rubber tree) is another common cause of anaphylaxis. People who are allergic to latex cannot allow it touch their skin, otherwise it could cause an anaphylactic reaction. Latex is most commonly found in balloons, condoms, food preparation gloves, rubber bands and some toys.


An anaphylactic reaction, while rare, can occur when taking any type of medication in people who are allergic to that medication. Sometimes people do not know they have an allergy to a specific medication until they have anaphylaxis - although this is rare.

No underlying reason

Very rarely, anaphylaxis will occur with no underlying reason that can be found.
