What Causes Allergies?

If you’re experiencing sneezing, itchiness or congestion,allergies may be responsible for your symptoms. Allergies are the body’s response to substances that do not cause a reaction in most people. Common allergens range from pollen and dust to certain foods and medications.

If you’re dealing with allergy symptoms, you’re not alone. More than 50 million people in the U.S. experience various types of allergies each year, making them the county’s sixth leading cause of chronic illness. Charleston ENT & Allergy can determine the source of your allergies and create a customized treatment plan to help you get back on your feet.

Why Do Allergies Lead to Uncomfortable Symptoms?

When people with allergies encounter a triggering substance, their immune system overreacts and produces antibodies that attack the allergen. These substances can be ingested, inhaled or touched.

These antibodies then travel to cells that release chemicals that cause an allergic reaction. This often results in symptoms in the nose, lungs, throat, sinuses, ears, lining of the stomach or on the skin.

Are There Different Types of Allergies?

  • Hay fever, also known as allergic rhinitis or seasonal allergies, can result in sneezing, itchiness in the nose, eyes or roof of the mouth; a stuffy nose; and watery, red or swollen eyes.
  • Food allergies can cause tingling in the mouth; swelling of the lips, tongue, face or throat; hives; or anaphylaxis.
  • Atopic dermatitis, also known as eczema, can make the skin itch, redden, flake or peel.
  • A drug allergy can result in hives, itchy skin, a rash, facial swelling, wheezing or anaphylaxis.
  • An insect sting allergy can cause hives, itchiness, chest tightness, cough or anaphylaxis.

What Are Risk Factors for Allergies?
