Preventing gangrene

There are a number of things you can do tohelp lower your risk of developing gangrene.

Foot care

If you have diabetes or another long-term condition that can cause Atherosclerosis (hardening or thickening of the arteries), it's importantyou take extra care of your feet.

If you have diabetes, you should have your feet checked at least once a year. However, you may needmore frequent check-ups if you have additional risk factors, such as peripheral neuropathy (numbness in the hands and feet), or a history of foot ulcers.

The advice listed below can help prevent a diabetic foot ulcer developing:

  • Check your feet daily forproblems such as numbness, discolouration, breaks in the skin, pain or swelling. Report problems to your GP immediately.
  • Avoid walking barefoot outside and wearing shoes without socks.
  • Don't use chemical preparations for corns and calluses or ingrown toenails . Instead, contact a podiatrist (a healthcare professional who specialises in foot care).
  • Wash your feet daily with warm water. Afterwards, make sure you dry your feet thoroughly, particularly between the toes.
  • Wear shoes that fit properly and don't squeeze or rub. Ill-fitting shoes can cause corns and callouses, ulcers and nail problems.

If you have a history of foot ulcers, wearing specially designed therapeutic or orthopaedic shoes can help prevent further ulcers developing.Your podiatrist may be able to provide you with specially made-to-measure footwear, or they may be able to recommend a stockist.

Smoking can cause your arteries to become blocked, resulting in a loss of blood supply to your arms or legs. This is known as peripheral arterial disease (PAD) .

If you decide to stop smoking, your GP will be able to refer you to an NHS Stop Smoking Service , which will provide dedicated help and advice about the best ways to give up. You can also call the NHS Smoking Helpline on0300 123 1044.

If you're committed to giving up smoking but don't want to be referred to a stop smoking service, your GP should be able to prescribe medical treatment to help with any withdrawal symptomsyou may experience.

Eating an unhealthy diet high in fat will make any existing atherosclerosis worse and increase your risk of developing gangrene.

Continuing to eat high-fat foods will cause more fatty plaques to build-up in your arteries. This is because fatty foods contain cholesterol.

There are two types of fat saturated and unsaturated. Avoid foods that contain saturated fats because they increase levels of " bad cholesterol " in your blood.

Foods high in saturated fat include:

  • meat pies
  • sausages and fatty cuts of meat
  • butter
  • ghee (a type of butter often used in Indian cooking)
  • lard
  • cream
  • hard cheese
  • cakes and biscuits
  • food containing coconut or palm oil

It may make you sweat but you'll still be able to hold a normal conversation. Examples include:

  • fast walking
  • cycling on level ground or with few hills
  • swimming
  • tennis

You should choose physical activities you enjoy because you're more likely to continue doing them.

It's probably unrealistic to meet these exercise targets immediately if you haven't exercised much in the past. Aim to start gradually and build up the amount of exercise you do over time.
