ALLERGIC REACTION Meaning and
Definition
-
An allergic reaction refers to an abnormal response of the immune system to a substance that is usually harmless. It is characterized by a range of symptoms that vary in severity from mild to life-threatening. Allergy-causing substances, also known as allergens, can trigger this response, leading to the production of antibodies called immunoglobulin E (IgE).
When a person with allergies comes into contact with an allergen, such as pollen, pet dander, food, medications, or certain chemicals, their immune system recognizes it as harmful. This recognition prompts the immune system to release chemicals, including histamine, into the bloodstream. Histamine is responsible for the classic symptoms associated with an allergic reaction, such as itching, hives, swelling, redness, nasal congestion, sneezing, coughing, wheezing, shortness of breath, and gastrointestinal discomfort.
Allergic reactions can manifest in different ways, depending on the individual and the specific allergen involved. While most allergic reactions are mild and merely inconvenient, some can be severe and life-threatening, leading to anaphylaxis. Anaphylaxis is a severe whole-body allergic reaction that can cause breathing difficulties, a rapid drop in blood pressure, and even loss of consciousness.
Treatment for allergic reactions can involve avoiding known allergens, taking antihistamines to alleviate symptoms, using corticosteroids to reduce inflammation, and carrying an epinephrine auto-injector for emergencies. An allergic reaction should be taken seriously, as prompt medical attention is essential to prevent complications and manage severe reactions safely.

Etymology of ALLERGIC REACTION
The word "allergic" comes from the Greek word "allos", meaning "other" or "different", and the Greek word "ergon", meaning "work" or "action". In this context, it refers to a reaction that is different from the normal response. The word "reaction" originated from the Latin word "re-", indicating "back" or "again", and the Latin word "actio", meaning "act" or "doing". Therefore, the term "allergic reaction" implies a response that is different or altered from the usual reaction.
