Allergic rhinitis, commonly called hay fever, is the inflammation of the nasal passages caused by allergic reaction to airborne substances like grass, tree and weed pollen. An allergy sufferer’s immune system has an exaggerated response to substances that are harmless to most individuals. Seasonal allergic rhinitis occurs when the levels of plant pollen are high – in the spring, summer and early fall. Perennial allergic rhinitis occurs all year and is caused by indoor environments.


An allergy is an exaggerated response to substances that, in most individuals, cause no difficulty.  Allergy is a name given to the way your body reacts when it mistakes ordinarily harmless substances (like grass, tree or weed pollen) for something harmful.

An allergy sufferer’s immune system overreacts to pollen.  Seasonal allergic rhinitis, also called hay fever, occurs in the spring and fall when the air is full of pollen.

Allergic rhinitis, referred to as hay fever, is an inflammation of nasal passages caused by an allergic reaction to airborne substances.  Seasonal and Perennial are the two types of allergic rhinitis.  Season occurs in the spring, summer, and early fall – plant pollens are at the highest levels during this time.  Perennial occurs all year and is caused by home or work environments.

Sometimes your physician can see signs of allergies:  Allergic shines – dark circles under your eyes or nasal crease – a line, rather like a wrinkle on your  nose that comes from rubbing it often.  The color of mucus in your nose is also important.  Clear mucus usually means allergy.  Yellow or green mucus usually means an infection.
