  • The Body

    The body is now ready for that allergen if it does enter the body again, because the antibody has attached to cells.
  • Sending out Signals

    When the allergen enters the body again the allergen binds to IgE antibodies and sends out signals.
  • Releasing Histamine

    The body then releases histamine throughout.

    The release of the large amounts of histamine causes irritation and swelling in areas on the body.

    Mouth swelling and itching, rashes, vomitting, stomach cramping, diahrrea, and swelling of the throat are all symptoms of an allergic reaction.
