-
A person consumes an allergan which causes a reaction that has never happened before.
-
After the person consumes the allergen, the body reacts by creating an IgE antibody which joins itself to cells in tissue throughout the body.
-
After the antibody joins with the cells, the body is prepared for that allergen if it enters the body again.
-
When the person consumes the allergen again, it connects to the antibodies and sends signals in order for the body to distribute huge quantities of histamine.
-
Irritation is casued by the large amount of histamine in the body.
-
The irritation differs between each person. They can be mild
reactions like hives or more severe like shortness of breath or death.
