Allergic Disease is on the Rise in Australia
Although we don’t know what causes allergies, most people learn to manage their condition.
Australia in particular has one of the highest rates of allergies in the world, with around one in five Australians having at least one allergic disease.
What is an allergy?
Allergies are the result of an overactive immune response.
The immune system, which normally recognises and responds to infections and cancers, reacts excessively to a trigger that is harmless to most people. The resulting response creates symptoms such as hives, swelling, redness and itching.
Allergic symptoms can be mild or severe. The most severe type of allergic reaction is called anaphylaxis and it can cause death without treatment.
After exposure to an allergen, allergic reactions are usually quick, within minutes or hours.
