What You Should Know about Allergies
What are allergies?
An allergy is a reaction by our immune system to a foreign substance, called an allergen. Seasonal nasal allergies are the most common. Year-round allergies are usually caused by indoor allergens such as dust mites or mold and animals and food.
Who is at risk?
Allergies can develop at any age, possibly even in the womb. Your risk is related to your parents’ allergy history.
What are the symptoms?
Runny nose, stuffy nose, sneezing, nasal itching, itchy ears and throat, and postnasal drip. Unlike cold symptoms these persist for weeks.
How are allergies treated?
The cure depends upon the severity of your allergy. A mild seasonal allergy is often best treated by avoiding the allergen and perhaps using an antihistamine to reduce the symptoms.
New antihistamines such as Allegra and Claritin cause less drowsiness, but you will need to see your doctor as they are available only by prescription.
A moderate or severe allergy should be treated by an allergist (a doctor who specializes in this field). The allergist can identify the allergen and provide shots to control the allergy. This can be a long process, but it is worth the effort.
Be sure to discuss allergies with your doctor.
