An allergy is an exaggerated immune response to substances (allergens) that are generally not harmful, such as tree or grass pollen, molds, pet dander, food or dust mites.Your immune system overreacts to these allergens by producing antibodies called Immunoglobulin E (Ig E).Ig E antibodies travel to cells and release certain chemicals that cause allergy symptoms.Seasonal allergic rhinitis is also called 'hay fever' or 'allergic rhinitis'. Other symptoms, such as a scratchy throat, cough, sneezing, and red and itchy eyes are also common with seasonal allergies.



A doctor can evaluate your allergy, help pinpoint the most likely cause, and advise on the most appropriate treatment.Your doctor will check your family history of allergies, ask about specific symptoms and when they occur, and question you about other allergy-related disorders, such as asthma, hives or eczema.Your nose, eyes and throat will be checked during a physical exam.Pinpointing the actual allergy may be easy in those with a predictable response to a given substance.

In others, a blood test or referral to a specialist may be needed. One way to help prevent allergies is to stay away from the allergen, but in many cases, this is not practical or possible.

For hay fever, staying indoors as much as possible during the allergy season, keeping doors and windows closed, using the dryer to dry clothes, and cooling the house down with an air conditioner may help.
