Seasonal vs. Year-Round Allergies: How to Tell the Difference

January 8, 2026

Not all allergies are seasonal. Understanding whether your symptoms are seasonal or year-round can help guide proper treatment and prevent unnecessary discomfort.

Seasonal allergies are typically caused by pollen from trees, grasses, or weeds and tend to flare during specific times of the year.

Year-round allergies are often triggered by:

  • Dust mites
  • Pet dander
  • Mold
  • Indoor allergens

Symptoms may look similar, but treatment strategies can differ significantly.

At Dr. Osborne’s allergy clinic in Portland, comprehensive testing helps determine the exact cause of symptoms. From there, a customized plan can be created to reduce exposure, control symptoms, and improve quality of life.

For patients searching for seasonal allergy treatment near me or long-term allergy relief, proper diagnosis is key.
