Hayfever

What is Hayfever?
Hayfever is an allergy (a sensitive reaction to basically harmless substances) to pollen from trees, grass or weeds. It is sometimes called allergic rhinitis (inflammation of the lining of the nasal passages).

How do you get Hayfever?
Allergies are extreme reactions to basically harmless substances. You get hayfever if you are one of a number of people whose body reacts to pollen in a different way to most (you are described as being sensitive to pollen). Hayfever comes on in the spring and summer when pollen levels are high.

How is Hayfever treated?

• Both mild hayfever, and that which occurs now and again (intermittent), can be treated using medicines called antihistamines. These work by blocking the action of a chemical called histamine that is released by the body during the inflammation (allergic) response. It is the main cause of symptoms in hayfever.
  
• Persistent symptoms and more severe disease are treated with anti-inflammatory medicines called steroids (of the glucocorticosteroid type), which often come in nasal sprays. These block the whole allergic response and are therefore more effective for those people who need a stronger medicine.
