Foot Problems and Amputation
Half the amputations performed each year are in people with diabetes, resulting most often from foot ulcers that don't heal. At least half of these can be eliminated through preventative foot care

Risk Factors Of Foot Problems
If you have any of the following, you are at risk for foot ulcers and amputations.
- loss of feeling in your feet
- pain in legs while walking
- changes in the shape of your feet
- previous foot ulcers
- diabetes more than 10 years and over age 60
- poor diabetes control
Causes Of Foot Problem
Foot problems in people with diabetes are usually caused by the following four factors. All of these can lead to injuries that result in amputation if left untreated.
Nerve Damage (Neuropathy). Sensory neuropathy causes a loss of feeling in the feet and legs. Symptoms include numbness or tingling in the feet or legs, or the inability to feel your feet at all. Neuropathy allows injuries (such as stepping on a tack) to go unnoticed.
Poor Circulation. People with diabetes frequently have poor circulation in their legs and feet. Reduced blood flow means the feet don't get the oxygen and nutrients needed, causing injured feet to heal slowly or not at all.
Infection. People with diabetes are more susceptible to infections than people without diabetes, and they're less able to fight off their infections due to a weakened immune response. Infections can quickly escalate and/or go undetected until they are quite serious. This can lead to ulceration of the skin and tissues-a very serious condition.
Foot Deformities. When a person with diabetes has neuropathy or poor circulation, foot deformities such as hammertoes or bunions can cause lesions. These lesions (such as corns, calluses, blisters, or ulcers) can lead to serious infections while putting stress on other parts of the foot.
Prevention
Examine Your Feet. The most important thing you can do to prevent foot ulcers and amputation is to examine your feet every day for sores, cuts, bruises or injury.
Find Out If You Have Normal Sensation In Your Feet. You may have lost the ability to feel normal sensation in your feet. This is sometimes called “loss of protective sensation.” In other words, you've lost the warning signals in your feet that protect you from injury. You can use a simple test to determine if you have lost any sensation in your feet.
Develop A Plan For Foot Care And Foot Protection. Your nurse can help you create this plan, which will help prevent future foot ulcers.
Make Sure Your Doctor Examines Your Bare Feet During Each Visit. And make sure your doctor checks the circulation in your feet at least once a year.
Wear Appropriate Shoes. Poorly fitting shoes can quickly lead to injury. Avoid wearing high heels and shoes with pointed or open toes. Socks provide a protective barrier around your feet to decrease the chance of irritation. Wear them at all times.
Check Your Shoes For Rough Spots Or Loose Objects. Before putting on your shoes, check for rough or worn edges and loose items that don't belong in your shoes, such as pebbles. These things can quickly cause irritation, injury and foot ulcers.
Avoid Heating Pads, Hot Water Bottles, And Hot Bath Or Tub Water On Your Feet. If you have less feeling in your feet, you may not feel something if it's too hot. And with less feeling, burns can occur without pain.
Don't Go Barefoot. Injuries while barefoot are the second most common cause of ulceration and amputation. Protect your feet by wearing shoes all the time.
Dry Your Feet And Between Your Toes After Bathing. Wetness between the toes may allow bacteria and fungus to grow, which may lead to serious infection.
Trim Toenails Carefully. Injuries from cutting your toenails can lead to infection, foot ulcers and amputation. Be sure to trim your toenails straight across, using only a nail clipper. Don't cut into the corners of the nails. If you can't care for your own toenails, have a family member, friend or podiatrist/nurse assist with the trimming.
Use Moisturizing Lotion Daily But Not Between The Toes.
