Allergies

Allergy literally means 'altered reaction'. Allergies cause the body to 'overreact' to what are normally harmless substances. Examples are house dust mite allergy, hay fever and food allergy. The immune system regards certain substances as intruders, against which it must 'arm' itself, resulting in a hypersensitivity reaction which can take various forms.
