| If you have a reaction to a substance, that
would not usually cause a reaction in a person, it
is called an 'allergy'. Common allergies include;
various foods, bee and wasp stings, dust and
medicines. Allergic reactions are caused by
hypersensitivity of the immune system. The immune
system normally protects the body against harmful
substances such as viruses, toxins and bacteria,
but allergies occur when the immune system reacts
to substances (allergens) that are usually
harmless | | |
