Allergic Rhinitis
Allergic
rhinitis is an inflammatory disease of the nose characterized by nasal congestion,
sneezing, itching of the nose, and nasal drainage. It can begin anytime in life, even in
early infancy. When left uncontrolled, it can lead to recurrent chronic sinusitis and
ear infections. There is evidence that when the allergic component is left untreated
during childhood, asthma can develop in up to 50 to 70% of patients.
Allergic rhinitis
is the most common allergic disease, affecting 40 million Americans. It costs over $40
billion per year to treat, and accounts for 3.8 million lost work and school days per
year. In addition to nasal symptoms and their complications, allergic rhinitis is
frequently associated with disturbing systemic symptoms of fatigue, malaise, irritability,
weakness, and poor concentration leading to poor school or work performance.
Allergic rhinitis can occur year round (perennial allergic rhinitis) or
seasonally (seasonal allergic rhinitis), or in combination (perennial allergic
rhinitis with a seasonal component).
PERENNIAL ALLERGIC RHINITIS
· nasal congestion and post-nasal drainage
are the most common
symptoms
· "sinus" symptoms
are quite common including pressure and
headaches about eyes
·
commonly associated with recurrent sinus infections
· most common allergens: animal dander, mold,
house dust mites, occupational factors, and foods
SEASONAL ALLERGIC RHINITIS (HAY FEVER)
· sneezing, watery runny nose, nasal congestion,
itching of nose, ears, and throat, and
itching and watering of eyes are
the most common symptoms
· most common allergens: grass pollen, tree
pollen, weed pollen, and mold spores
TREATMENT (see
MANAGEMENT of ALLERGIC DISORDERS)

(collects pollen and mold).
· Keep windows in bedroom and autos closed, and use air
conditioning, if possible.
· Wash hair before going to bed to wash out allergens.
· Limit facial hair during pollen season (collects pollen
and mold).
· Keep basement dry and avoid crawl spaces, if mold
sensitive
