-
A person consumes an allergen
-
After the subject consumes the allergen, the body immediately makes an antibody
-
the antibody then will attach itself to the cells located through the entire body to prepare for another consumption of the allergen
-
then when the food allergen enters the body once more, the allergen attaches itself to the antibodies and then sends signals out to release histamine.
-
the release of the histamine causes irritation and swelling throughout the body.
-
Some of the results of the swelling and irritation can vary depending on the persons but can cause hives, anaphylaxis, and shortness of breath.
