Allergic rhinitis is an allergic inflammation of the nasal airways, caused when an allergen, such as pollen, dust or animal dander is inhaled by an individual with a sensitized immune system. The word, Rhinitis which means irritation of nose, is derived from Rhino which means nose.
It is also called as Pollinosis, if caused by pollen and Hay fever, if caused by specific grass pollen. Hay fever is a misnomer as there is neither any fever nor any hay, but since grasses shed their pollens into the air at about the same time that hay is being cut, the common term hay fever is used. When Allergic Rhinitis occurs during a specific season, it is called Seasonal Allergic Rhinitis and when it occurs round the year, it is called Perennial Allergic Rhinitis.
When an individual comes in contact of an allergen, in such individuals, the allergen triggers the production of the antibody immunoglobulin E, which binds to mast cells and basophiles containing histamine inflammatory mediator. This usually causes sneezing, itchy and watery eyes, swelling and inflammation of the nasal passages, and an increase in mucus production. Symptoms vary in severity between individuals. Very sensitive individuals can experience hives or other rashes.
Allergic Rhinitis is usually caused by Proteins, mainly plant proteins, called pollen. However, particulate matter in polluted air, and chemicals such as chlorine and detergents, which can normally be tolerated, can greatly aggravate allergic rhinitis. Heredity and environmental exposures can contribute to a predisposition to allergies.
