Food Allergy

The prevalence of food allergies is increasing in North America. An estimated 6-8% of Canadian children have a food allergy.

The 9 most common food allergens are peanut, tree nuts, egg, cow's milk, wheat, soy, fish, shellfish, and sesame. Symptoms usually present within minutes of eating the food and can include mouth itching, hives, swelling, vomiting, coughing, or difficulty breathing. The severity of allergic reactions are often unpredictable and can lead to anaphylaxis. Therefore, it is important to identify the allergic trigger so it can be avoided and carry an epinephrine autoinjector. In infants and young children, food oral immunotherapy (OIT) is a treatment option I provide in my clinic.

If someone is having a serious allergic reaction, give them epinephrine (Epipen®) and call 9-1-1.
