Dear Doctor, my father and elder sister have Type 2 diabetes.
Am I also at risk of developing diabetes? How do I prevent
it from occurring? – Omeruah.
One of the most important risk factors for developing diabetes,
especially Type 2 diabetes is what is referred to in medical
language as family history of diabetes.
Since you are from the same gene pool as your father and sister,
you also are at risk of developing this type of diabetes.
There are certain steps you may be taking which greatly increases
the probability of your developing diabetes.
This includes lack of exercise, if you are overweight or obese,
and some indiscretion in your diet.
The scientifically proven methods of preventing or delaying
the development of diabetes in those with and without a family
history of diabetes includes moderate exercise of at least
thirty minutes a day for at least four days in a week.
Exercise is known to enhance the effectiveness of Insulin
which is the chemical that an organ called the pancreas produces
to help keep our blood sugar under control. If you are overweight
or obese, you need to shed some weight to a level such that
the size of your waist will not be more than 38 inches if
you are a male and 32 inches if you are a female or when what
is called Body Mass Index (BMI) is used, your value should
be between 18.5 and 24.9.
It is known that people who are overweight or obese are at
increased risk of developing Type 2 diabetes.
Discretion in your diet is also of paramount importance. Ensure
variety and moderation in whatever you consume.
Avoid the food with high salt and fat contents from fast food
joints as much as possible and take fruits and vegetables
daily.
Dear Sir, you said that after road traffic accidents, the
commonest causes of amputation of the legs in Nigeria are
ulcers or wounds on the feet of someone with diabetes. How
does this occur? How do I protect my feet?– Mrs Arigbede
Foot ulcers are common in people with diabetes. Those with
poor control have reduced wound healing ability. Ulcerations
and amputations have tremendous impacts on people’s
lives; leading to increased dependence, psychological stress
and social isolation.
Damage to the nerves called neuropathy due to diabetes not
only affects nerves that help us to feel, but also nerves
that help the muscles to move well and the ones that keep
the skin from becoming too dry.
When this nerve damage is present, some people may have no
symptom at all while others may experience lack of feeling
in the feet (numbness), severe peppery sensation, severe pain,
sensation that is likened to walking on cotton wool, while
others may experience pricking sensations on the legs and
feet, reduced sweating, dry skin and development of cracks
and fissures. Relatively simple precautions can reduce amputation
rates.
Your shoes must not be tight fitting; in fact you may wear
a shoe one size above your normal size so as to give adequate
room for the toes.
Such shoes must have very hard soles to prevent penetration
by sharp objects, but must have soft and well - padded insides.
Tight fitting shoes lead to skin damage and ulcers. Woolen
and not nylon stockings should be worn.
Daily self foot inspection which must include the areas in
between the toes and the sole of the feet must be carried
out. The purpose of the inspection is to look for ulcers and
other abnormalities like calluses, swellings and fissures
in order to seek prompt medical assistance.
You should not walk barefoot but should wear protective footwear
both at home and outside.
Cut your nails in a well lit area after a bath when the nails
will be soft and use a nail cutter but never a blade. Do not
sit cross-legged as this reduces blood supply to the legs
and feet, neither should you sit close to hot objects.
