Types of Allergens

Almost any substance can cause an allergic reaction. Common types of allergens include:

  • Animals
  • Dust
  • Cockroach
  • Mold, mildew and fungi
  • Trees, grass and weeds
  • Foods
  • Insect stings
  • Medications

Allergies can cause a variety of symptoms including:

  • Sneezing
  • Watery eyes and nose
  • Itchy eyes and nose
  • Congestion

Food allergies and bee stings can cause symptoms, which range from annoying to life-threatening. These may include the above symptoms plus nausea, vomiting and difficulty breathing. The Food Allergy Network estimates that 125 people die each year from food allergy reactions. Statistics also indicate that about 25 people die each year from insect stings, however this figure could be much higher.
