If you have diabetes, your blood sugar levels are too high.
Over time, this can damage your nerves and blood vessels.
Nerve damage from
diabetes can cause you to lose feeling in your legs and feet. You may not feel
a cut, a blister or a sore. This lack of feeling is caused by nerve damage,
also called diabetic neuropathy. Foot injuries such as these can cause ulcers
and infections. Serious cases may even lead to amputation.
Poor blood flow. Damage
to the blood vessels can also mean that your legs and feet do not get enough
blood and oxygen. Poor blood flow makes it hard for a sore or infection to
heal. This problem is called peripheral vascular disease, also called PVD.
Smoking when you have diabetes makes blood flow problems much worse.
The US National
Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) suggests what you can do to take care of your feet:
Wash your feet in
warm water every day. Make sure the water is not too hot by testing the
temperature with your elbow. Do not soak your feet. Dry your feet well,
especially between your toes.
Look at your feet
every day to check for cuts, sores, blisters, redness, calluses, or other
problems. Checking every day is even more important if you have nerve
damage or poor blood flow. If you cannot bend over or pull your feet up to
check them, use a mirror. If you cannot see well, ask someone else to check
your feet.
If your skin is dry,
rub lotion on your feet after you wash and dry them. Do not put lotion
between your toes.
File corns and
calluses gently with an emery board or pumice stone. Do this after your
bath or shower.
Cut your toenails
once a week or when needed. Cut toenails when they are soft from washing. Cut
them to the shape of the toe and not too short. File the edges with an emery
board.
Always wear slippers
or shoes to protect your feet from injuries.
Always wear socks or
stockings to avoid blisters. Do not wear socks or knee-high stockings that
are too tight below your knee.
Wear shoes that fit
well. Shop for shoes at the end of the day when your feet are bigger. Break
in shoes slowly. Wear them 1 to 2 hours each day for the first few weeks.
Before putting your
shoes on, feel the insides to make sure they have no sharp edges or objects
that might injure your feet.
