Dr. Samira Jeimy says the increased stress from the transition and the new or changing exposures that happen in September can impact allergic and immunologic disease.

A food allergy occurs when the immune system mistakenly treats a food protein as dangerous. It creates antibodies called immunoglobulin, and on later exposure these antibodies trigger the release of histamine, which can affect the respiratory, gastrointestinal, skin or cardiovascular systems.

In severe cases the reaction can develop into anaphylaxis, a rapid and potentially fatal response. Health experts advise anyone at risk to carry an epinephrine device such as an EpiPen, which can stop the reaction if used promptly.

Dr. Allan Grill stresses that life‑threatening outcomes are preventable when students are educated, have their EpiPen on hand, recognize the warning signs, and know how to use the device correctly.

Jennifer Gerdts, executive director of Food Allergy Canada, adds that when a clear plan is in place and everyone knows about the child’s allergy, the children feel more confident and safe at school.

Because stress and new environmental contacts are inevitable in September, parents, teachers and students should review allergy action plans, practice inhaler and EpiPen use, and keep open communication. Proper preparation can keep the school year healthy for children with food allergies.
