Chronic rhinitis is a condition, characterized by the swelling of membranes in the nose, that causes many unpleasant symptoms in the nose, ears, and throat. A case of rhinitis is considered chronic if it persists for at least a few weeks or months. Nasal symptoms include sneezing, runny nose, and congestion. Other common symptoms include postnasal drip (mucus collecting in the back of the throat), a sore throat, and a cough.
There are two main types of chronic rhinitis: allergic and nonallergic. An allergic reaction to identifiable triggers causes allergic rhinitis, and nonallergic rhinitis carries the same symptoms but is caused by localized irritants. Some actions can help alleviate the irritating symptoms of chronic rhinitis.
Allergic rhinitis occurs when the nasal passages become irritated due to the body's production of histamine after an encounter with certain particles. Mucous thickens to keep potentially harmful substances from entering the body. The most common allergic triggers are pollens, molds, insects, and animals. Avoiding allergens usually requires making changes around the home. Dust mites, cockroaches, and ladybugs are the most common insect culprits.
Reducing indoor humidity (between thirty and fifty percent), clutter removal, and laundering bedding weekly in hot water can help eliminate insects. Humidity reduction is also crucial in the prevention of mold formation. Removing a pet from the home is the most effective way to avoid pet allergies. Outdoor triggers like pollen are difficult to avoid altogether, though keeping windows closed in the home and car provide some relief.
