Conditions We Treat: Allergies
People who suffer from allergies have immune systems that respond to common allergens in the environment — such as pollen and animal dander — by release of chemical mediators from the body such as histamine. The histamine and other chemical mediators which are released by the body then cause the allergy symptoms to develop.
Allergies: What You Need to Know
- About 45 million Americans suffer from allergies.
- Common symptoms of allergies include frequent sneezing, itchy eyes, nose or throat, stuffy nose, runny nose and postnasal drip.
- Allergies may also play a part in other disorders of the ear, nose and throat area, such as ear infections, hoarseness and sinusitis.
- Both adults and pediatric allergy patients can easily undergo evaluation and diagnostic allergy testing and receive their results within the same day. Allergies are diagnosed with either a skin test, where small amounts or allergen are placed on the skin, or with blood testing.
- The treatment of allergies typically involves the combination of avoidance of the allergens if possible, medications and immunotherapy (allergy shots or sublingual drops/tablets that are taken under the tongue at home). Medications helpful in treating allergies include nasal steroids and antihistamines.
