What is Allergic Disease?

An allergy arises in the body when it produces an immune response to things such as cats or pollen that don’t affect most people. If you get too close to something that you’re allergic to (also called an allergen), you may experience symptoms like sneezing, shortness of breath, and itchy, watery eyes.

Approximately 60 million Americans suffer from allergic diseases. Allergic diseases, such as allergic rhinitis (hay fever), food allergy, and atopic dermatitis (eczema) are common among all age groups in the United States. Allergies can also play a major role in serious conditions like asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening reactions called anaphylaxis. Food allergies and reactions to the venom of stinging insects (wasps, bees, and hornets) are often associated with these severe reactions. On average, most people are allergic to 2 or 3 sources. The top 8 sources that cause allergic reactions are :

  • Grasses
  • Ragweed
  • Cat
  • Food
  • House dust mites
  • Birch
  • Dog
  • Venom
