What is the definition or description of: corn allergy?

Coorn Allergy: A corn allergy is an exaggerated immune response due to exposure to corn protein. The reaction can present with typical symptoms of hives, respiratory symptoms (cough, wheeze, shortness of breath), GI symptoms (abdominal pain, vomiting), swelling, loss of consciousness, and can be fatal. Symptoms typically present within minutes to a couple hours after ingestion or contact.

Food allergy: Ige, the immune protein that is involved in an allergic reaction, can be specific for corn. If you have a high ige specific for corn then you are allergic to corn and may develop wheezing, rashes, diarrhea and anaphylaxis when eating corn.
