Are you one of 50 million Americans who suffer from allergies? Allergies are the fifth-leading chronic disease in the U.S. among all ages, and the third most common chronic disease among children under age 18, according to the Asthma and Allergy Foundation of America.
Allergy is characterized by an overreaction of the human immune system to a foreign protein substance (â€œallergenâ€) that is eaten, breathed into the lungs, injected or touched. This immune overreaction can result in symptoms such as coughing, sneezing, itchy eyes, runny nose and scratchy throat. In severe cases it can also result in rashes, hives, lower blood pressure, difficulty breathing, asthma attacks, and even death.
In a series of new videos, Emory University pediatric allergist and immunologist Karen DeMuth, MD, discusses seasonal allergies, allergy triggers, coping methods, treatments and common allergy myths.
In another video series, DeMuth explores the link between asthma and allergies and the impact of air pollution on people with asthma.
DeMuth is an assistant professor of pediatrics in the Emory School of Medicine.Â She practices at the Emory-Children’s Center and Childrenâ€™s Healthcare of Atlanta.
