Gangrene is a serious condition where a loss of blood supply causes body tissue to die. It can affect any part of the body but typically starts in the toes, feet, fingers and hands.

Gangrene can occur as a result of an injury, infection or a long-term condition that affects blood circulation.

Symptoms of gangrene include:

redness and swelling in the affected areaeither a loss of sensation or severe pain in the affected areasores or blisters in the affected area that bleed or produce a foul-smelling pus

You should see your GP immediately if you're worried you may have gangrene

Who's affected

Anyone can develop gangrene, particularly after a serious injury, but there are certain groups of people who are more at risk.

These include people with long-term conditions that can affect the blood vessels, such as:

diabetes – a lifelong condition that causes a person's blood sugar level to become too highatherosclerosis – where the arteries become clogged up with a fatty substance called plaque, narrowing them and restricting blood flow peripheral arterial disease – where a build-up of fatty deposits in the arteries restricts blood supply to leg musclesRaynaud's – where blood vessels in certain parts of the body, usually the fingers or toes, react abnormally to cold temperatures.
