Step 1
When a person first eats an allergen it creates no adverse affects on the outside. -
Step 2
The body creates IgE antibodies, a protein that detects harmful substances, in reaction to the allergen. -
Step 3
The antibodies attach themselves onto cells all around the body to brace for the next time the specific allergen is eaten. -
Step 4
When the allergen is eaten the second time the allergen attaches itself to the IgE antibodies. This sends out a signal to the rest of the body to release the compound called histamine that triggers the immune system response. -
Step 5
The histamine causes the allergic reaction which includes swelling and irritation in certain parts of the body. -
Step 6
the severity of the reaction is unique with every person. They may experience anaphylaxis, which could result in death, or they may just experience hives and a shortness of breath.
