This is a disorder of carbohydrate metabolism in which sugars in the
body are not broken down to produce energy, due to a lack of the pancreatic
hormone “Insulin”. This disorder is characterised by an inability to reabsorb water, which results in
an increased urine production, excessive thirst and excessive eating. The
accumulation of this sugar leads to its appearance in the bloodstream (hyperglycaemia), and then in the urine. As this sugar cannot be
broken down to produce energy, the body utilises its fat storage as an energy source. This alternative
source of energy leads to disturbances of the acid base balance and
accumulation of ketones (Ketosis) in the blood, this eventually leads to convulsions,
which precede diabetic coma.
Diabetes, which starts in
childhood or adolescence (Juvenile-onset diabetes), is more severe than that
beginning in middle or old age (Maturity-onset diabetes).
Insulin
Dependent Diabetes
In this condition patients have little or
no ability to produce the hormone Insulin and are entirely dependent on insulin
injections for survival.
Non-Insulin
dependent diabetes Usually
occurs after the age of 40. The pancreas retains some ability to produce
insulin but it is inadequate for the body’s needs. Patients may require advice
on diet or treatment with oral hypoglycaemic drugs.
With both types of
Diabetes, diet must be carefully controlled with adequate carbohydrates for the
body’s needs. Lack of balance in the diet, or in the amount of insulin taken,
leads to hypoglycaemia. This is a deficiency of glucose in the bloodstream
causing muscular weakness, incoordination,
mental confusion and sweating, which may lead to hypoglycaemic coma. Long-term
complications of Diabetes include thickening of the arteries, which can affect
the eyes. It is therefore important that the eyes are checked regularly.
The
Feet. Diabetes is a disease with widespread complications
throughout the body, and the feet are one of the main areas in which
complications occur.
Neuropathy. The complications of Diabetes can seriously affect
the feet. Neuropathy is a disease of the peripheral nerves causing weakness and
numbness. All types of nerve fibres are involved and autonomic, motor and
sensory functions are affected. Neuropathy may improve with control of
Diabetes.
Ischaemia. This is a vascular disease where there is inadequate
flow of blood to a part caused by constriction of the blood vessels.
Diabetes may affect the
nerves so that pain signals arising from the feet cannot reach the brain. This
means that the Diabetic loses the warning signals produced by injury.
Similarly, if the blood flow to the feet is limited or absent, then the ability
of the body to fight infection is removed. This allows the infection to spread.
This is the danger: An infection
may easily develop on the feet and the diabetic patient may be completely
unaware of this problem due to lack of feeling!
Prevention is
Better than cure.
A new test has been
developed that offers a reliable and efficient indication of whether a Diabetic
is likely to develop the Diabetic foot syndrome called Peripheral Neuropathy.
Peripheral Neuropathy is a
disease of the sensory nerves, which often results in the insidious development
of painless ulceration and gangrene of the toes and feet.
If you have been diagnosed
as having Diabetes then this test is recommended every six months.

Care of the
Diabetic feet
As a Diabetic may
experience a reduction in feeling, other senses must be used, especially the
eyes and hands, to detect the earliest signs of injury or infection. If these
signs are neglected serious problems may develop. The Diabetic should follow
these simple rules:
1. Wash feet daily in warm
water, not hot water. (Test temperature first with the elbow or even a
thermometer). Take care to remove debris from between the toes and dry the feet
carefully and thoroughly. Apply moisturising
cream to any dry areas.
2. Examine the feet
carefully after each wash for any signs of cracks, corns, blisters etc. If you
find anything unusual, however small, come to the Foot Clinic. If you cannot
see the soles of your feet, sit on a bed or on the floor and view them through
a large mirror. If your eyesight is poor, ask someone to examine them for you.
3. Always dress in roomy,
woolly socks - two pairs if necessary. If your circulation is poor, wear slacks
(women,) or long johns (men).
4 If you have had
Neuropathy of the feet, and if you have them, always wear the special shoes
that have been made for you. They will help you remain free of corns and callouses, and will protect your feet from injuries that you
cannot feel, e.g. drawing pins in the sole of the feet etc.
5. Never walk about
barefoot in the house, and wear slippers when you get out of bed during the
night.
6. Try to remember to check
your footwear each time you put your shoes on, in case hairgrips or other small
objects have dropped into them.
7. Do not sit too close to
a fire as you may burn your legs without realising it. Take hot water bottles out of the bed before you
get in, and wear bed-socks if necessary.
8. Do not attempt to cut
your own toe nails, and most certainly, do not under any circumstances use corn
plasters, or any other form of substance which could damage your skin. Come to
the
Kirkintilloch Foot Clinic regularly for
routine nail trimming and foot inspections.
Remember
protection is better than cure.
