Allergies 101

If you’re diagnosed with an allergy, it means that your body has an overactive immune response to a certain substance. Your immune system produces antibodies that incorrectly inform your body that a particular substance is harmful. When you’re exposed to that substance, you experience a reaction. The substances to which you are allergic are called allergens, or allergy triggers. Some of the most common triggers include pollen, mold, pet dander, insect stings, medications, and some foods.

When exposed to an allergy trigger, you’ll experience symptoms such as a runny nose, itchy eyes, and congestion. The exact symptoms you experience depend on your specific allergy. Food allergies, for example, can cause swelling of the facial area. Some allergic reactions are life-threatening, which is why it’s important to understand and manage your allergies.
