Allergic Rhinitis :
Allergic Rhinitis is usually called hay fever, and it provides a swelling sensation that the nasal region feels stuffed up with an itchy feeling, such that more of the same natures occur for a person's nose. Basically, it's simply an immune system reaction to the elements that view the body as hazardous, such as dust mites, pollen from trees and flowers, pet dander, and mold. It is the allergen that causes allergic reactions in allergic rhinitis. For instance, when spring or fall is near, the pollen that is emitted by a plant results in allergic reactions. Dust, pet hair, and mold spores inside your house cause a blockage all the year. A patient suffering from allergic rhinitis may sneeze, run, stuffy nose, itchy eyes, and scratchy throat. People even get tired by these disadvantages. This can be avoided by completely avoiding the allergens, windows shut when pollen counts are high, mattresses or pillows covered with dust mite covers. Over the counter drugs also exist, anti-histamines like cetirizine make it impossible for the symptoms to arise in the first place. A class of medications known as steroids and nasal sprays are designed to reduce swelling inside the nose. More serious cases of the condition demand allergy shots, whereby the patient becomes responsive to the allergen to the point that he would not respond violently to it anymore. Even lifestyle changes are not so difficult but, in fact, by picturing oneself cleaning up his living space and using an air purifier, symptoms become easier to live with.
