-
A person eats a food or substance that causes an allergic reaction for the first time.
-
The person swallows the food or substance and then the body creates an antibody or a protein that can detect the harmful substance.
-
Then the antibody attatches to the cells found in tissues all over the body. This prepares the body to expect the food or substance if it enters the body again.
-
When the food or substance enters the body again, it attaches to antibodies. It then sends out signals to the body and releases large amounts of histamine.
-
The histamine then causes swelling and irritation in some parts of the body.
-
The result of histamine can vairy from person to person. It can range from mild hives to anaphylaxis.
