Allergic Reactions, What to Look For & How to Help

What is an allergic reaction? How can I help someone having an allergic reaction? What does an allergic reaction look like? Can an allergy be fatal? What does an extreme allergy or Anaphylaxis look like? What causes allergies? These are some of the questions that we have received within our first aid courses, to begin an allergic reaction is an immune response causing hypersensitivity to substances that either contact or enter the body.

Substances causing the allergy are called allergens, these can be almost anything from bee venom, pollen, pet dander, shell fish and many other substances. When your body comes into contact with an allergen it reacts as if the substance was a pathogen or harmful substance. This causes the body to have an immune response and release histamines, histamines are involved with the body’s immune response causing tissue inflammation or swelling at the sight of contact with the allergen. Depending on where the body begins to swell this can range from a slight irritation to extremes that may be life threatening “Anaphylaxis“.

Depending on the person’s sensitivity to the substance their body’s immune response “Allergy” may be slow to react or almost instantaneous. The severity of the reaction depends on each individuals immune system and sensitivity.
