Many of the different allergic reaction types can trigger an anaphylactic reaction. However, anaphylactic reactions affect the whole body, rather than just one area or system. Because of this, anaphylactic reactions are much more serious. There are some symptoms that are specific to anaphylactic reactions. They are:

  • Anxiety
  • Flushing or a feeling of warmth throughout the body
  • Itchy rash
  • Light-headedness
  • Difficulty breathing
  • Tingling in the mouth
  • Unconsciousness (this is caused by the rapid decrease in blood pressure)
  • Weak pulse

Some people have certain characteristics that put them at a greater risk for suffering from allergies. Some of these characteristics are:

  • Age (children are more prone to allergies than adults)
  • Asthma
  • A family history of allergies
  • A personal history of allergies (some people who experience allergic reactions react to more than one kind of trigger)
