Allergic rhinitis, also called hay fever, is an allergic reaction that causes sneezing, congestion, itchy nose and sore throat. Pollen, pet dander, mild and insects can lead to hay fever symptoms. Hay fever can make you feel awful, but you can find relief with lifestyle changes, allergy medications and immunotherapy (allergy shots).

 Allergic rhinitis (hay fever) is an allergic reaction to tiny particles in the air called allergens. When you breathe in allergens through your nose or mouth, your body reacts by releasing a natural chemical called histamine.

Several indoor and outdoor allergens cause hay fever. Common causes include dust mites, mild, pet dander and pollen from trees and plants. 

Symptoms of hay fever include sneezing, nasal congestion and irritation of the nose, throat, mouth and eyes. Allergic rhinitis is not the same as infectious rhinitis, otherwise known as the common cold. Hay fever is not contagious.

CAUSES OF ALLERGIC RHINITIS

Allergic rhinitis occurs when your body’s immune system reacts to an irritant in the air. The irritants (allergens) are so tiny that you can easily inhale them through your nose or mouth.

Seasonal and perennial allergies can result from many allergens, including:

• Dust mites that live in carpets, drapes, bedding and furniture.

• Pollen from trees, grass and weeds.

• Pet dander (tiny flakes of dead skin).

• Mold spores.

• Cockroaches, including their saliva and waste.

SYMPTOMS OF ALLERGIC RHINITIS

 Symptoms of hay fever include: 

• Nasal stuffiness (congestion), sneezing and runny nose.

• Itchy nose, throat and eyes.

• Headaches, sinus pain and dark circles under the eyes.

• Increased mucus in the nose and throat.

• Fatigue and malaise (general feeling of discomfort).

• Sore throat from mucus dripping down the throat (postnasal drip).

• Wheezing, coughing and trouble breathing.
