Inflammation of the mucus membranes of the nose and upper respiratory tract can occur in response to the irritant. In allergic rhinitis, the hypersensitive response of the immune system occurs in response to airborne allergens. This is a common disorder, affecting at least a quarter of the population.
Causes of Allergic Rhinitis
Pollens which are released into the air causes allergic rhinitis. Seasonal plants, glasses, flowers, trees, and ragweed are common sources. In addition, mold spores, animal dander, and household dust can produce the condition. Occasionally, it can be precipitated by using medications, such as aspirin and anti-inflammatory drugs or by the overuse of nasal decongestant sprays.
Signs and Symptoms of Allergic Rhinitis
Sneezing, red swollen eyes, and a runny nose are the most common symptoms. Itching in the throat, coughing, and sneezing may occur. When the condition is chronic, it can impair the sense of smell and taste.
