Anaphylaxis (pronounced anna-fill-axis) is a life-threatening allergic reaction triggered by some serious food allergies, like eggs or peanuts. Many Canadian adults and children are at risk of this reaction.
Symptoms of a severe allergic reaction can start within minutes of coming into contact with an allergen, and can include any of the following:
- skin: itching, redness, swelling, hives, rash
- airway: trouble breathing, swallowing, speaking, coughing, nasal congestion or hay fever-like symptoms
- stomach: nausea, pain, vomiting, diarrhea
- heart: weak pulse, pale/blue colour, weak, lightheaded, fainting, shock
- other: anxiety, sense of doom, loss of consciousness
If you are concerned that you or your child may have a severe food allergy, talk to your doctor for more information.
