Why
proper foot care is so important to people with diabetes.
The
foot is especially affected by diabetes because:
- diabetes
damages the nerves (damage can occur to the foot and not be detected)
- this is called peripheral neuropathy.
- diabetes
also affect the circulation. Poor circulation can affect the ability
of the body to heal when damage occurs.
-
those with diabetes are more prone to infection - the body's processes
that normally fight infection respond slower and often have trouble
getting to infections due to the poor circulation.
-
diabetes can also affect the joints, making them stiffer
- other
diabetes complications that can also affect the foot, for example,
kidney disease (affects proteins that are involved in wound healing)
and eye disease (can't see the foot to check for damage).
As
a consequence of these factors a number of things can go wrong:
- the
foot may get damaged and you do not know about (for example, your
shoe rubs a sore onto a toe that gets infected - you can not feel
it because of the peripheral neuropathy - you can not heal very
well due to the infection and poor circulation).
- foot
ulcer are common
-
infections can spread
- the
ultimate of this process is an amputation. Diabetes is the main
cause of amputations.
- Charcot's
joints is another complication of diabetes in the foot, especially
if peripheral neuropathy is present - the neuropathy cause a numbness
(imagine spraining your ankle and not knowing you have done this.
You will continue to walk on it - imagine the damage that this
would do.

The "Do's"
and "Don'ts" of foot care if you have diabetes.
If you have diabetes, there are a lot of things you need to do to
prevent the problems from developing in your foot:
1)
Wash your feet daily (use a mild soap and lukewarm water). Dry very
carefully, especially between the toes. It often helps to use talcum
powder to dust the foot to further reduce moisture, however be certain
to remove all the powder after dusting, as it should not leave a
residue between the toes. If the skin is dry, use a good
emollient - BUT, not between the toes).
2)
Inspect your foot daily (check sores, cuts, bruises, changes to
the toenails; use a mirror to look under the foot if you can not
see it).
3) Look after your health (loose weight; stop smoking; exercise;
reduce your alcohol consumption)
4) Look after your feet:
- cut
toenails straight across and never cut into the corners; use an
emery board or file on sharp corners.
- do
not try to remove corns
and callus yourself - see a Podiatrist for this;
NEVER use commercial corn cures - this is so important in those
with diabetes as it is so easy to damage the skin.
- avoid
going barefoot, even in your own home (this lessens the chance
of some accidental damage)
5)
Proper fitting footwear
is very important. Poorly fitted shoes are a common cause of problems
in the foot of those with diabetes. Some advice:
- make
sure the shoe fitter is experienced.
- new
shoes should be comfortable when purchased and should not need
a "break-in" period.
- they
should fit both the length and width of the foot, with plenty
of room for the toes.
- avoid
shoes with high heels, pointed toes or tight around the toes (these
put too much pressure on parts of the foot and can contribute
to ulcers)
6)
See a Podiatrist, at least annually.

Podiatric
Treatment for those with diabetes
Podiatrists have an extremely important role to play
in the prevention and management of complications of the foot in those
with diabetes. All those who are at risk for a problem should have
that risk status assessed at least annually (more if the risk is greater).
The Podiatrist should communicate this risk status to other members
of the health care team. Advice should be given on how to reduce the
chance of damage happening, what to do to prevent it and what to do
if something does go wrong. Regular
foot care from a Podiatrist is a key way to prevent problems from
developing in those who are at risk.
When
something does go wrong, see a Podiatrist immediately. Waiting a
"few days to see what happens" before seeing someone may
be the difference between a good and poor outcome. The sooner treatment
is started the better.
