Symptoms of Maize Allergies
Maize (commonly known as corn) is an increasingly common allergen. However, because there have been relatively few scientific studies on maize allergy, it is not a well-understood condition. Different individuals with maize allergies may each experience very different symptoms. If you think you are allergic to corn, talk to a doctor, who will perform testing to determine if you are truly allergic.

Common Symptoms

If you have a maize allergy, you may experience hives, swelling, asthma symptoms, gastrointestinal problems, and itching or tingling in the mouth after coming in contact with corn-based products.
-
Unusual Symptoms
-
More unusual symptoms of a maize allergy may include depression, tiredness, eczema, mood swings, difficulty concentrating, respiratory and sinus conditions, and trouble sleeping.
Anaphylaxis
-
There are relatively few reported cases of anaphylaxis (a severe, life-threatening allergic reaction) resulting from maize allergy. Signs of anaphylaxis include trouble breathing and a swollen throat.
Warning
-
People who have a true maize allergy should avoid corn and all its derivative products, (except for corn oil) including corn syrup and maltodextrin.
Considerations

Because maize or corn derivatives are present in many commercially packaged foods, strict avoidance of all maize products can be very difficult for people with this allergy.
