Corn allergy: Should I be worried?

Corn allergy arises if the immune system erroneously identifies corn as a threat. As a response of the body, antibodies are released to deal with the allergen. On the next exposure to the allergen, the immune system triggers the release of histamine and other chemicals that cause the allergy symptoms.

Nevertheless, this allergy is considered rare. It might arise due to cross contamination with a different allergen including soy. Even minimal traces of soy can instigate a reaction among highly sensitive individuals.

What are the indications?

A severe reaction can progress to anaphylaxis that can be dangerous. The symptoms that might arise include:

  • Difficulty breathing due to the swollen throat and air passages

It is vital to consult a doctor right away if corn allergy is suspected or if any of these indications are present.

Preventive measures

An allergic reaction can be prevented by bringing your own food when travelling. When eating outside, ask the server regarding the ingredients used in the dishes being ordered.

In case the individual experienced a severe allergic reaction to corn in the past, a medical necklace or bracelet must be used. This will help others know that the individual has corn allergy.
