Food Allergy Overview
- A food allergy is an overreaction of the immune system that can affect any system of the body, including the respiratory, cardiovascular, gastrointestinal, and skin systems
- Ingestion of even a minute amount of the allergen can trigger this overreaction and cause a variety of symptoms ranging from mild nausea or itching to anaphylaxis (a systemic allergic reaction that can kill within minutes)
- There is no cure for food allergies. Strict avoidance of the allergenic food is the only way to prevent a potential life-threatening reaction
- An allergic reaction can occur up to two hours after ingestion
- The severity and progression of an allergic reaction is unpredictable; a seemingly mild reaction can turn fatal within minutes
- Anaphylactic reactions are treated by prompt administration of epinephrine. Time is of the essence and may mean the difference between life and death. Transport to an emergency room must follow
