The Common Types of Allergy Triggers

The Common Types of Allergy Triggers

Allergy symptoms are very common. You likely either experience them yourself or know someone who does. Many different forms of allergies affect people, some more commonly than others. If you’re curious about these forms, keep reading for the common types of allergy triggers that can produce allergy symptoms in certain people.

Airborne Allergens

Airborne allergens, as the name suggests, travel through the air and can affect your respiratory system. Some of the most common offenders of airborne allergies include:

  • Pollen: Pollen often affects people with seasonal allergies. Pollen levels tend to spike around the changes in the seasons, which causes greater symptoms in people with pollen allergies.
  • Animal fur, dander, and dust mites: Animal allergy triggers can be anything from fur to saliva. Some people with animal allergies are more sensitive than others. Dust mites and dust can also cause similar respiratory reactions.
  • Mold: Mold is one airborne trigger that can be hard to detect because it presents itself similarly to seasonal allergies. Watch for the unique symptoms of mold allergies after periods of high moisture, such as rain and floods.

Food Allergies

Food allergies are also some of the most common types. Almost any food could be a trigger for a specific person, but some of the most common food allergies include:

  • Peanuts
  • Milk
  • Eggs
  • Tree nuts
  • Fish
  • Crustaceans
  • Wheat
  • Soy

There are many more food allergies, but the ones above tend to be more common than others.


You may be surprised to learn that another common type of allergy triggers is medication. Some of the most noted medications to which patients have adverse reactions include:

  • Penicillin
  • Amoxicillin
  • Cephalosporins
  • Anesthetics
  • Immune system suppressants

Like food allergies, people can be allergic to just about any type of medication, so it’s important to report any adverse symptoms of an allergic reaction to your doctor.

Were you surprised by any of the common allergens on this list? Allergies are different for everyone, and they can range from mild to severe in terms of reactions. Always keep in mind whether you or someone you know has an allergy when you’re dining, traveling, or even visiting the doctor’s office.
