The body's immune system recognizes the presence of these allergens and starts a reaction to prevent their invasion. In most people this is not a problem, but in some patients the immune system is overactive and identifies normally harmless particles as dangerous and start to produce an excessive reaction that actually causes inflammation. This is known as allergy and the substances causing it are known as allergens.
People who suffer from allergies seem to have a reduced resistance to respiratory infections, and have more severe symptoms when an infection occurs.
Allergies often cause lost work days, decreased work efficiency, poor school performance and a negative effect on the enjoyment of ones life. |
