Allergies

Whether you are facing a sudden health crisis, unexplained ill-health or a recognisable minor ailment, the NHS* Home Healthcare Guide is here to help.

An allergic reaction is when the body's defence system responds to a substance that doesn't affect most people. Allergies can be caused by many different substances and cause a wide range of symptoms.

They can develop at anytime in life. Most allergies are unpleasant but not dangerous, although in a few people they can cause serious illness.
