With the inhaled allergens, the most common problem is allergic rhinitis, also known as hay fever. In actuality, the allergy is not to hay but to various tree, dust, mold and weed pollens, especially ragweed. The majority of persons develop symptoms in summer and fall, but with those senstive to molds and dust, symptoms may be year round. Skin testing is available with an allergist to determine the substances to which one is allergic, Usuallly, in mild cases, the history of seasonal problems will point out the responsible allergen. For example, tree pollens are common in early spring, grass pollen in early summer and weed pollens in early fall.
Treatment includes avoidance of the responsible allergen.
Avoidance of certain types of bedding may reduce the exposure to molds, feathers and dust. In some cases, a nasal steroid spray may be beneficial in reducing swelling and drainage. If sinusitis develops, a course of antibiotics may be necessary. Finally, desensitization with allergy shots may be helpful in some instances. This series of injections help build up resistance to certain allergens, especially those difficult to avoid.
