ALLERGENS Meaning and
Definition
-
Allergens are substances that are capable of inducing an allergic reaction or causing an allergic response in individuals who are sensitive or allergic to them. These substances can be found in various forms, such as compounds, proteins, or particles, and are commonly known to trigger an immune response in the body. When a person is exposed to an allergen, their immune system mistakenly identifies it as harmful and releases chemicals, such as histamines, in an attempt to protect the body. This immune response results in allergy symptoms, ranging from mild to severe, depending on the person and the specific allergen.
Common examples of allergens include pollen, dust mites, pet dander, certain foods (such as nuts, shellfish, or dairy), insect venom (from bee or wasp stings), medications (like penicillin), and certain chemicals (such as latex or fragrances). Allergens can enter the body through various routes including inhalation, ingestion, or direct contact with the skin or mucous membranes.
Identifying specific allergens can be crucial in managing allergies, as avoidance or reduction of exposure to these substances is generally the most effective way to prevent an allergic reaction. People who suffer from allergies may undergo allergy testing, which can help determine the specific allergens they are sensitive to. Treatment options for allergies often involve allergen avoidance, over-the-counter or prescription medications for symptom relief, allergy shots (immunotherapy), or in severe cases, emergency treatment with epinephrine.

Etymology of ALLERGENS
The word "allergens" is derived from the combination of two Greek words, "allo" meaning "other" or "different", and "ergon" meaning "work" or "action". The term was coined in the early 20th century, specifically in 1906 by the Viennese pediatrician Clemens Pirquet, to describe substances that cause an abnormal immune response or allergic reactions in individuals.
