Foot Problems
People with diabetes are at much higher risks of developing foot problems which result in ulcers, so you should pay close attention to foot care.
Like many of the complications of diabetes, early treatment can prevent long term damage to your health.

Risk Factors For Foot Problems
If you have any of the following, you are at risk for foot ulcers.
- 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
Foot problems
in people with diabetes are usually caused by the following four
factors.
1. 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.
2. 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.
3. 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.
4. 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.
Untreated ulcers often require long periods of bed rest, surgery, skin grafts and in some cases amputation, so these small preventative measures are a worthwhile investment in your health.
- Examine your feet:
The most important thing you can do to prevent foot ulcers 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. Ask your doctor about a monofilament test. Or have your doctor test your feet.
- Develop a plan for foot care and foot protection:
Your doctor 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, slip on shoes or thongs 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 with your hands 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. 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. 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.
See your doctor or Podiatrist promptly if you have any of the following:
- redness or swelling of the foot or ankle
- change in the size or shape of the foot or ankle
- pain in the legs at rest or while walking
- open sores, no matter how small
- nonhealing wounds
- ingrown toenails
- corns or calluses with skin discoloration
- lack of hair growth on the foot
