Causes of Allergic angioedema


Angioedema is often the result of an allergic reaction.

This is where the body mistakes a harmless substance, such as a certain food, for something dangerous. It releases chemicals into the body to attack the substance, which cause the skin to swell.

Angioedema can be triggered by an allergic reaction to:

  • certain types of food - particularly nuts, shellfish, milk and eggs
  • some types of medication - including some antibiotics, aspirin and non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen
  • insect bites and stings - particularly wasp and bee stings
  • latex - a type of rubber used to make medical gloves, balloons and condoms

Angioedema caused by allergies is known as "allergic angioedema".
