Allergic rhinitis can also be triggered by common indoor allergens such as the dried skin flakes, urine and saliva found on pet dander, mold, droppings from dust mites and cockroach particles. This is called perennial allergic rhinitis, as symptoms typically occur year-round.

In addition to allergen triggers, symptoms may also occur from irritants such as smoke and strong odors, or to changes in the temperature and humidity of the air. This happens because allergic rhinitis causes inflammation in the nasal lining, which increases sensitivity to inhalants.

Many people with allergic rhinitis are prone to allergic conjunctivitis (eye allergy). In addition, allergic rhinitis can make symptoms of asthma worse for people who suffer from both conditions.

Symptoms

Allergic rhinitis symptoms include:

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

Hay fever symptoms tend to flare up in the spring and fall. Perennial allergic rhinitis symptoms are year-long.

Diagnosis

An allergist / immunologist has specialized training and experience to diagnose specific allergens that trigger your illness, or to determine if your symptoms are non-allergic. Your allergist will take a thorough health history followed by allergy testing. Skin tests or blood tests are the most common methods for determining your allergic rhinitis triggers.
