Viennese paediatrician Baron Clemens von Pirquet coined the term "allergy" (from the Greek "allos" meaning changed or altered state and "ergon" meaning reaction or reactivity) in 1906 [ 1 ]. Von Pirquet used the term to describe an altered reaction he had observed in patients, which he put down to the influence of external factors, an allergen , on the immune system.

Allergies are hypersensitivity reactions of the immune system to specific substances called allergens (such as pollen , stings , drugs , or food ) that, in most people, result in no symptoms .

The most severe form of allergy is Anaphylactic shock , which is a medical emergency.

Various types of classifications exist.
