Introduction Why is foot care important to people with diabetes? Diabetes can cause nerve damage (called peripheral neuropathy) that reduces sensation in your feet. If you have neuropathy, you can have an injury or condition on your foot that requires medical care without even knowing it. Small injuries may become infected. Diabetes may also affect blood flow in your legs and feet, making it harder for cuts or sores to heal. Then a small infection can become very serious. Foot infection is the most common reason for hospitalization of people with diabetes. And

Inngrown toenaiils can happenn if you cut intto the coorners of yourr toenails wheen you trim thhem. This conddition can alsoo be causeed by wearing shoes that arre too tight. A bunion forms wheen the big to slants s towardd the small toees, and a bumpp o the big toe. This spot cann get red, sore, and infecteed. formss at the base of Bunions often run in i the family and a can also be b caused by w wearing shoess with pointed p toes. Plantaar warts, whicch form on the bottom of thhe feet, are caaused by a virrus. They tend t to go away without treeatment.

Hamm mertoes form when a foot muscle m gets weak, w shortening the tendonns, whichh then retract the toe, caussing it to curl under u the fooot and creatingg a bump at the joint onn the top of thhe toe. These areas can beccome sore, annd hamm mertoes can caause problem ms in walking and a in finding comfortable shoess.

How will I know if I'm at risk for diabetic foot problems? About 15% of people with diabetes will develop foot ulceration at some point, and 14% to 24% of these will have to have an amputation. The majority of these - almost 60% - occur in people who are 65 and older. The risk for foot ulceration leading to amputation increases in people over 40 who have had diabetes for 10 years or longer. People are at high risk for foot problems if they have loss of protective sensation - such that you can't feel an injury, or vascular disease causing poor blood flow in your feet and legs. Other risk factors are skin disorders such as calluses, especially with redness or bleeding under a callus, and nail abnormalities such as very thick nails. Structural/bony deformities such as hammertoes or bunions and limited joint mobility are also risk factors. In addition, people who do not have good control of their blood glucose are at increased risk, as are those who have cardiovascular, eye, or kidney complications. People who have had foot ulcers or amputation previously have, by definition, the necessary risk factors for future problems. The American Podiatric Medical Association has identified specific conditions that warn of impending foot problems - see the box.

Warning Signs of Foot Complications • • • • • • • •

Changes in skin color Elevation in skin temperature Swelling of the foot or ankle Pain in the legs Open sores on the feet that are slow to heal Ingrown and fungal toenails Bleeding corns or calluses Dry cracks in the skin, especially around the heel

What can I do to prevent diabetic foot problems? Every person with diabetes - with or without any of these risk factors - should take proper care of their feet. Routine foot inspection and preventive care can minimize or prevent foot problems. Below are things to make sure you ask your doctor about: • •

• •

You should have a thorough foot examination by a professional at least once a year. This includes checking the sense of feeling and the pulses in your feet. (See box.) Ask for a risk evaluation. Specific follow-up and treatment will be based on what risk category your feet are in. Ask for special instructions for people with high-risk feet, if applicable. If you have lost some sensation in your feet, they should be visually inspected at every visit. Take off your shoes and socks at every visit and make sure this happens. Ask your provider to check your footwear to make sure that the style and fit are appropriate for the condition of your feet. Ask if special shoes would help your feet stay healthy.

Components of a good foot exam: At least once a year, everyone with diabetes should have a thorough foot examination. It should include an assessment of: • • • • • •

Protective sensation - using a monofilament or vibratory sensation test Foot structure Biomechanics - including any limits in joint mobility or problems with gait and balance Vascular status - including questions about painful walking and determination of pulses in your feet Skin integrity - especially between your toes and on the ball of your foot Increased pressure on the soles of your feet; areas of warmth, redness, or callus formation may be indicative of tissue damage

Many diabetes treatment programs operate regular foot clinics to help patients with routine foot care and to make sure that preventive measures are taken. Some pharmacists specializing in diabetes care offer similar programs. Be sure to take advantage of any foot care programs that are available to you.

Preventive foot care - for all Of course, the best way to prevent foot problems is to keep your blood glucose under control. But there are also specific things you should do EVERY DAY to make sure your feet stay fit. Here are some of them:

Examine your feet EVERY DAY to look for cuts, sores, blisters, redness, etc. If you have anything of that nature, and it doesn't heal in a day or two, notify your doctor. If you have trouble seeing or reaching your feet, ask someone to help, or use a mirror to help you see better. Wash your feet EVERY DAY with lukewarm water and mild soap. Dry them carefully and thoroughly with a soft towel. Dust your feet with talcum powder, which will help keep them dry. Don't soak your feet - this will make your skin too dry. If you have dry skin on your feet, use a moisturizing lotion to prevent cracking - but NEVER use a lotion or cream between your toes, as this can lead to infection. If you have corns or calluses, DO NOT cut them, don't use corn plasters or liquid corn and callus removers - they can damage your skin. Check with your doctor or foot care specialist who may advise you to use a pumice stone to smooth calluses or corns. Keep your toenails trimmed. Trim them with toenail clippers after you have washed and dried your feet. Trim the nails following the shape of your toes, and smooth them with an emery board or nail file. Don?t cut into the corners of the nail, which could trigger an ingrown toenail. If your nails are very thick or yellowed, have a foot care specialist trim them. Don't go barefoot - not even indoors. Always wear socks, stockings, or nylons with your shoes to help avoid blisters and sores. Choose soft socks made of cotton, wool, or a cottonpolyester blend, which will help keep your feet dry. Avoid mended socks or those with seams, which can rub to cause blisters. Avoid wearing socks or hose that are too tight around your legs. Knee-high or thigh-high stockings as well as elasticized men's dress socks can constrict circulation to your legs and feet.

Choose the proper footwear - for all Choosing the right footwear is an important part of foot care, since poorly fitted shoes are involved in as many as half of serious foot problems. Here are some tips for choosing the best footwear: 1.

Wear well-cushioned walking shoes or athletic shoes. If you have foot deformities such as hammertoes or bunions, you may need extra-wide shoes or depth shoes. Depth shoes have more room in them to allow for different shaped feet and toes or for special inserts made to fit your feet. If problems are severe, custom-molded shoes are available. Medicare provides coverage for some special shoes; your doctor or foot care specialist can help determine if you qualify. 2. Don't wear shoes with high heels or pointed toes. They can create pressure, which might contribute to bone and joint disorders as well as diabetic ulcers. 3. Don't wear open-toed shoes or sandals with a strap between the first two toes. They increase the chance that you'll injure a toe. 4. When you buy new shoes, be sure your feet are properly measured and fitted. Your feet can change size and shape, so an experienced shoe fitter should measure them whenever you

  IX

  DR.  TARIK  TORKI [email protected]   YOUR   WAY  FOR  HEALTHY  LIFE   HTTP://TARIKTORKI.JIMDO.COM get new shoes. Shoes should fit both the length and width of your foot, with room for your toes to wiggle freely. 5. Your new shoes should be sturdy and comfortable. They should have leather or canvas uppers, which breathe to keep your feet from getting sweaty. Avoid vinyl or plastic shoes, because they don't stretch or breathe. 6. When you get new shoes, break them in gradually so you won't get blisters. 7. Shake your shoes before you put them on. Even a small pebble in your shoe can lead to problems.

Special care for high-risk conditions If you do have any of the high-risk conditions, there are specific things you should do to keep your feet healthy. • • • • • •

If you have neuropathy or evidence of increased pressure on the soles of your feet, wear well-cushioned walking shoes or athletic shoes. If you have lost some sensation in your feet, be sure to carefully inspect them often to identify any problems early. If you have calluses, have a foot care specialist treat them. If you have bony deformities such as hammertoes or bunions, you may need extra-wide shoes or depth shoes. In extreme cases, custom-molded footwear may be needed. Promptly treat minor skin conditions such as dry skin or athlete's foot to keep them from progressing. Have a complete foot examination every 3 to 6 months.

A formal, comprehensive program has been developed at the Gillis W. Long Hansen's Disease Center in Carville, LA, known as the "LEAP program" for Lower Extremity Amputation Prevention. It consists of 5 relatively simple activities: • • • • •

Annual foot screening to identify people who have lost protective sensation Patient education in self-management, with emphasis on proper foot care Daily self-inspection of the foot Appropriate footwear selection Management of simple foot problems such as dry skin, nail and callus care, and basic wound management

In a number of large clinical centers where formal preventive care programs such as this have been implemented, the rate of amputations has been reduced by as much as 85%. Related articles • •

Treatments: Foot ulcer | Ulcers treatment | Infection | Off-load Pressure | Improve blood flow | Promote healing

What if I do get a diabetic foot ulcer? It is estimated that about 15% of people with diabetes will develop a foot ulcer sometime during their lifetime. Fortunately, up to 86% of foot ulcers will heal when treated properly. A foot ulcer is defined as a break in the skin or deep sore; they are most often located on the ball of the foot, an area of repeated stress. If you develop any kind of sore or wound on your feet that doesn't heal in a day or two, it's very important that you see your doctor or foot care specialist right away. Untreated lesions or ulcers can become infected quickly; even when treated, foot ulcers may not heal well in people with diabetes.

How are diabetic foot ulcers treated? Your doctor may x-ray your feet to make sure the bone is not involved. If the results are not clear, you may have an MRI scan to help your doctor determine the extent of the lesion. Treatment must address all of the factors involved in wound healing: • • •

Infection - which stops or delays the normal wound repair process. Repeated trauma during the wound healing process - which continually destroys new tissue. Decreased blood flow - which reduces the amount of oxygen and nutrients getting to the tissues.

Treat the infection

The doctor will thoroughly clean the wound to remove all infected tissue; in severe cases, this may be done in the operating room. Early, aggressive wound cleaning (called "debridement") has been shown to heal these wounds more rapidly. If there is an infection, your doctor will prescribe antibiotics. If the infection is serious, you may be hospitalized to receive intravenous antibiotics. Dressings are used to prevent further trauma, to minimize the risk of infection, to relieve local pain, and to optimize the environment for healing. A moist wound environment is important for wound healing to occur. You can help by keeping the area clean and moist at all times and using the medications your doctor has prescribed for you. It's important that you only use the medications your doctor has suggested. People used to use cleansers or antiseptics such as hydrogen peroxide on these types of wounds, but

  DR.  TARIK  TORKI [email protected]   YOUR   WAY  FOR  HEALTHY  LIFE   HTTP://TARIKTORKI.JIMDO.COM it is now known that they actually delay wound healing. They also dry out the tissue, and it is now believed that a moist environment stimulates more rapid wound healing.

Off-load pressure

Depending on the location of your foot ulcer, you may need to keep pressure off the area. This is called "off-loading" and means avoiding all mechanical stress on the wound so that it can heal. If there is no infection, a total contact cast may be used to relieve pressure. Or your doctor may recommend using "non-weight-bearing" devices such as orthopedic shoes, a walker, crutches, or even a wheelchair or bed rest - these can help healing by relieving pressure on the injured part of your foot. If your doctor has suggested keeping weight off of your foot, it's important to do so. Keep your foot elevated as much as possible.

Improve blood flow

If there is evidence of impaired blood flow to your feet, then your doctor may consider a surgical procedure called "revascularization." This involves bypassing or implanting a graft past lesions in the arteries that are obstructing blood flow. These procedures have been as successful in restoring blood flow for people with diabetes as in others and have been shown to help achieve rapid and durable healing of diabetic foot ulcers. They have also been shown to decrease the need for amputation.

Promote healing

New treatments such as recombinant growth factors and bioengineered skin patches are now available to help improve healing of foot ulcers. Growth factor gels contain a protein that helps the ulcer fill in with healthy tissue, so it heals faster and better than it would otherwise. Human skin cells are processed and grown in the laboratory to produce bioengineered skin, or skin equivalents, which are applied to the foot ulcer to enhance the process of wound healing. Foot care experts are encouraged by the early results of these treatments, which they say "are healing diabetic foot wounds faster and preventing amputations." Used with traditional approaches such as removing pressure, the new high-tech treatments reduce healing time, infection, hospitalization, and amputation while improving the quality of life. They've been called "a winning combination to reduce the needless number of lower extremity amputations in this country." Other treatments are sometimes used but, according to the American Diabetes Association, they have not been adequately tested in clinical trials to prove their worth. These include hyperbaric oxygen, electrical stimulation, cold laser, and heat treatments. Related articles • • •
