The term allergy is given to special
sensitivity of the body that makes it react
with an exaggerated response of the natural
immune defence mechanism to the introduction
of an otherwise harmless foreign substance.
Hay fever in summer is caused by an allergy
to one or more kinds of pollen. Many
asthmatics are allergic to certain kinds of
dust or to microorganisms in animal fur or
feathers. There are many different kinds of
allergies, producing a range of effects.
Some people experience skin reactions, such
as dermatitis, from drugs, cosmetics or
household cleaners, some suffer gastric
upsets due to allergens in food. A severe
allergic reaction may produce profound
shock. Various drugs can be used to
counteract allergic symptoms, including
antihistamines and steroids.
