Amputation and diabetes

Maxwell Adeyemi

GOOD DIABETES management and regular foot care help prevent severe foot sores that are difficult to treat and may require amputation.

Diabetes complications can include nerve damage and poor blood circulation. These problems can lead to skin sores (ulcers) on the feet that can get worse quickly.

The good news is that managing your diabetes and taking care of your feet can help prevent foot ulcers.

When you get a foot ulcer, it’s important to get care immediately. Most lower leg and foot removals begin with foot ulcers. An ulcer that won’t heal causes severe damage to tissues and bone. It may require surgical removal (amputation) of a toe, a foot or part of a leg.

Some people with diabetes are at higher risk than others. Factors that lead to a higher risk of amputation include:

* High blood sugar levels

* Smoking

* Nerve damage in the feet (peripheral neuropathy)

* Calluses or corns

* Foot deformities

* Poor blood circulation to the arms and legs (peripheral artery disease)

* A history of foot ulcers

* A past amputation

* Vision problems

* Kidney disease

* High blood pressure, above 140/80 millimetres of mercury (mm Hg)

Preventing foot ulcers

The best way to prevent complications of diabetes – including foot ulcers – is to manage your diabetes. This includes eating a healthy diet, exercising regularly, checking your blood sugar regularly, and taking your medicine correctly.

Taking care of your feet will help prevent problems. It can also ensure you get medical care quickly when you see problems. Proper foot care includes the following:

*
Look at your feet daily. Check your feet once a day for blisters, cuts, cracks, sores, redness, tenderness or swelling. If you have trouble reaching your feet, use a hand mirror to see the bottoms of your feet. Put the mirror on the floor if you can’t hold it, or ask someone to help you.

*
Wash your feet every day. Wash your feet in lukewarm (not hot) water once a day. Dry them gently, especially between the toes. Use a pumice stone to gently rub the skin where calluses easily form.

Use a moisturising cream or lotion on the tops and bottoms of your feet to keep the skin soft. Preventing cracks in dry skin helps keep bacteria from getting in.

*
Don’t remove calluses or other foot lesions yourself. To avoid hurting your skin, don’t use a nail file, nail clipper or scissors on calluses, corns or warts. Don’t use chemical wart removers. See your provider or foot specialist (podiatrist) to remove any of these issues.

*
Cut your toenails carefully. Cut your nails straight across. Carefully file sharp ends with an emery board. Ask someone for help if you can’t trim your nails yourself.

*
Don’t go barefoot. To keep from hurting your feet, don’t go barefoot, even around your house.

*
Wear clean, dry socks. Wear socks made of material that pulls sweat away from your skin. This includes cotton and special acrylic fibres – not nylon. Don’t wear socks with tight elastic bands. These bands reduce circulation. Avoid socks with seams that could irritate your skin.

*
Buy shoes that fit correctly. Buy comfortable shoes that provide support and cushioning for the heel, arch and ball of the foot. Avoid tight-fitting shoes and high heels or narrow shoes that crowd your toes.

*
Don’t smoke. Smoking makes it harder for your blood to go through your body. It also reduces the amount of oxygen in your blood. These problems can make wounds worse and slow down healing. Talk to your provider if you need help to quit smoking.

*
Schedule regular foot check-ups. Your provider or podiatrist can look at your feet for signs of nerve damage, poor circulation or other foot problems. Have a foot exam at least once a year, or more often if recommended by your provider.

Danger signs in foot care

If you notice any of these signs on your foot, they are red flags to get aggressive with and take immediate action:

* Ingrown toenails

* Blisters

* Flesh-coloured bumps with dark specks (plantar warts) on the bottoms of your feet

* Athlete’s foot

* An open sore or bleeding

* Swelling

* Redness

* Warmth in one area

* Pain (though you may not feel anything if you have nerve damage)

* Discoloured skin

* A foul odour

* An ulcer that lasts longer than one to two weeks

* An ulcer bigger than 3/4 inch (two centimetres)

* A sore that doesn’t quickly begin to heal

* An ulcer so deep you can see the bone underneath

When amputation

is the only option

Treatments for foot ulcers depend on the wound. Most of the time the treatment is to remove dead tissue or debris, keep the wound clean, and help with healing. Wounds need to be checked often, at least every one to four weeks.

When the ulcer causes severe loss of tissue or an infection that threatens your life, an amputation may be the only treatment.

After surgery, other medical professionals that should be involved in your treatment may include:

* An endocrinologist, who is a physician with special training in the treatment of diabetes and other hormone-related disorders.

* A physical therapist, who can help you regain strength, balance and co-ordination. A physical therapist can also teach you how to use an artificial (prosthetic) limb, a wheelchair or other devices to help you move around better.

* An occupational therapist, who specialises in therapy to improve everyday skills. This can include teaching you how to use products to help with everyday activities.

* A mental health provider, such as a psychologist or psychiatrist, who can help you address your feelings about the amputation or cope with how other people react.

* A social worker, who can assist with finding services and planning for changes in care.

Even after amputation, it’s important to follow your diabetes treatment plan. People who have had one amputation are at higher risk of having another.

Eating healthy foods, exercising regularly, controlling your blood sugar and not smoking can help you prevent more diabetes complications.
