Anaphylaxis is a very serious and possibly life-threatening allergic reaction. This severe allergic reaction occurs when the immune system releases a flood of chemicals, such as histamines, when exposed to seemingly nonthreatening substances.

What Causes Anaphylaxis?

Anaphylaxis is often caused by certain foods. Other common causes of this severe allergic reaction include:

  • Foods
  • Latex
  • Insect stings, mainly wasps, bees and ants
  • Certain medications
  • Exercise following consumption of trigger foods

Symptoms of Anaphylaxis

  • Severe eye or facial itching
  • Breathing and swallowing difficulties
  • Cramps
  • Abdominal Pain
  • Vomiting
  • Diarrhea
  • Angioedema
  • Hives

The symptoms of anaphylaxis can quickly evolve into anaphylactic shock, so it is important to treat these symptoms immediately.
