Allergies can change over the course of your lifetime. While much is unknown about allergy, that seems to be static.

Maybe you have a friend whose had to give up shellfish, because he/she broke out in hives the last time they went to Red Lobster. Perhaps you were surprised to discover you have a severe insect allergy after a recent bee sting ended in a hospital visit – but you swear you were stung as a kid, and it wasn’t that bad.

According to Dr. Harold Kim, president of the Canadian Society of Allergy and Clinical Immunology,allergy conditions such as hay fever, can lessen as we age, while others, such as insect allergy, can become more deadly.
