Causes of Allergies

Allergies are very common. Over the past several decades, there has been a dramatic rise in the prevalence of allergies in both adults and children. Over time you can outgrow allergies, and you can develop new ones.

Both your genes and your environment play a role in your risk factors for developing allergies.


You may be at an increased risk of developing allergies if you:

  • Have a family history of allergies
  • Have asthma, sinusitis, postnasal drip, or eczema

You’re at an increased risk of having allergies if you have family members with asthma, environmental allergies, sinusitis, postnasal drip, or eczema. Also, having one type of allergy makes you more likely to be allergic to other things as well.


The Most Common Allergens Are:

  • Indoor Allergens such as dust mites, mold, and animal dander
  • Outdoor Allergens such as pollen (trees, grasses, ragweed) and mold
