Allergic rhinitis is a condition that affects the airways in the nose. It is caused by an allergic reaction to certain environmental allergens, such as dust, pollen, animal dander, and mold. Symptoms include sneezing, a runny nose, nasal congestion, and itchy, watery eyes. Allergic rhinitis can be divided into two main types: seasonal and perennial.
Seasonal Allergic Rhinitis
Seasonal allergic rhinitis, also known as hay fever, is an allergic reaction to airborne particles from pollen, grass, and weeds. Symptoms usually begin in the spring and last until the fall. Common symptoms include sneezing, a runny nose, nasal congestion, and itchy, watery eyes.
Perennial Allergic Rhinitis
Perennial allergic rhinitis is an allergic reaction to indoor allergens, such as dust, pet dander, and mold. Symptoms usually occur year-round and can be worse in certain seasons. Common symptoms include sneezing, a runny nose, nasal congestion, and itchy, watery eyes.
Non-Allergic Rhinitis
Non-allergic rhinitis is a condition characterized by nasal congestion, sneezing, and a runny nose. It is not caused by an allergic reaction, but is instead caused by irritants in the air, such as smoke, perfumes, strong odors, and changes in weather.
