Allergic rhinitis is one of the most commonly diagnosed health disorders among children. Commonly called hay fever, allergic rhinitis is an inflammation of the inner lining of the nose that occurs when an allergic individual encounters an airborne allergen such as pollen, mold, dust mites or animal dander.

Symptoms of allergic rhinitis include runny nose, nasal congestion, breathing difficulties, coughing and itchy, watery eyes. Many people view allergic rhinitis as a nuisance that is unlikely to seriously harm children. However, allergy symptoms can have a profound effect on a child’s health, behavior and ability to learn.

In 80 percent of cases, allergic rhinitis develops in a person before the age of 20. Boys are more likely to develop allergic rhinitis than girls. Several studies have found that, as with asthma, rates of allergic rhinitis and other allergies appear to be climbing among children. The reason for this is not yet fully understood.
