Frostbite is damage to the tissues of the body caused by low temperature. Frostbite can happen in the UK, for example if you are climbing, hiking, sailing, etc. and expose yourself to temperatures below freezing with inadequate clothing. It can also happen when you are skiing abroad.

Any part of the body may be affected by frostbite however the parts most likely to be affected are the tip (extremity) of the nose, ears, hands and feet.

The damage to the tissues is caused by the formation of ice crystals, which expand and rupture cells. Damage to tissues is also caused by the closure of small arteries carrying vital oxygen and blood supply to the affected area.

If only the tissues near the surface and the skin are affected then you will probably make a complete recovery. However, if blood vessels are affected, the damage is more likely to be permanent. Gangrene (dead tissue) may occur and amputation will be necessary.
