What is an allergy?

An allergy occurs when a foreign substance that is usually considered harmless triggers an immune response in a susceptible individual, leading to a variety of unpleasant symptoms. If you have allergies, exposure to substances such as pollens, pets, dust, mold, and foods can release chemicals in the body that cause symptoms such as a stuffy nose, itchy eyes, sneezing, drainage and wheezing.

You may have allergies if you experience the following symptoms:

  • Nose: Stuffy, runny, sneezing, itchy, postnasal drainage, facial pressure
  • Eyes: Watery, itchy, bloodshot
  • Skin: Hives, rash, dry/itchy skin
