What is Hay Fever?

Hay Fever- you or someone you know probably suffers from this condition. For most people, the feeling comes every spring. Do watery itchy eyes, congestion, nonstop sneezing, or just that constant tickle in your throat haunt you as the flowers start to bloom. As unfortunate sounding as this may be, the seasonal hay fever sufferers have it easy compared to the who suffer from perennial, or year round, allergies.  As a fellow "allergy sufferer" I can relate to having the constant wad of tissues secured in my pockets or purse for both the exacerbations in spring and having to be in the presence of mold year round.

However these symptoms are very well known, but the confusion begins with what Hay Fever really is. Hay Fever, or sometimes known as allergic rhinitis, occurs when the presence of an allergen which would be completely harmless, is perceived as being just that opposite and triggers an immune response. This allergen could be from pollen, mold, dust mites, pet dander, cockroaches etc. (The in depth pathophysiologic explanation will be brought up in a future post). The higher levels of these allergens cause a more intense response and sensitization with exposure- that's why for seasonal sufferer's, the very high levels of pollen in the spring can leave some feeling miserable.

The most common symptoms experienced by hay fever include the initial sneezing, watery itchy eyes, altered smell or taste, thin watery nasal discharge, sustained nasal congestion. Throughout chronic exposure there may be headache, congestion, pressure, nasal polyps, post nasal drip (which will exacerbate a cough). The constant congestion may also lead to snoring and daytime drowsiness from difficulty sleeping.

So what can you do? There are plenty of OTC medications (which will be explained more in a future post), such as antihistamines, mast cell stabilizers, intranasal corticosteroids, and leukotriene receptor antagonists (LTRAs). These are all triggered at symptom relief because there is no real "cure" once the antibodies have been made to the specific antigen- however immunotherapy (or allergy shots) can be used if trigger is identified and if medications are not effective. People often do nasal rinses or other alternative methods. The main thing that can be done is to identify the allergen and avoid it.
