Pollen Allergies

Rhinitis (Hay Fever-Pollen)

There are two common types of rhinitis: allergic and non-allergic.

Allergic rhinitis, happens when the immune system mistakenly identifies a typically harmless substance (allergen) as an intruder. The response to the allergen is the release of histamine that cause symptoms in the nose, throat, eyes, ears, skin and roof of the mouth.

Seasonal allergic rhinitis (hay fever) is most often caused by pollen carried in the air during different seasons.

Non-allergic Rhinitis
One out of three people with rhinitis symptoms do not have allergies. Non-allergic rhinitis usually effects adults and may cause year-round runny nose and nasal congestion symptoms. This condition differs from allergic rhinitis because the immune system is not involved.

Symptoms

Allergic rhinitis symptoms include:

  • Itching in the nose, roof of the mouth, throat, eyes
  • Sneezing
  • Stuffy nose (congestion)
  • Runny nose (post nasal drip)
  • Tearing eyes
  • Dark circles under the eyes
