Diabetes
is a major risk factor for foot problems including the
tragic and frightening experience of amputation. In

Diabetes mellitus is a metabolic disorder in which the body’s
cells are unable to properly use glucose (blood sugar). Normally,
glucose is consumed from the diet, digested and then passed into
the cells with the help of insulin (produced by the pancreas). Glucose
is required for growth and energy.
In people with diabetes, either the pancreas is unable to produce
sufficient insulin (Type 1) or the body’s cells are unable
to properly use insulin (Type 2). The result is that glucose builds
up in the blood and eventually passes out in urine (taking with
it, the body’s main source of energy).
Additionally, this oversupply of glucose can damage small blood
vessels and nerves in the lower limbs and feet (as well as elsewhere
in the body) leading to serious foot complications.
In fact, a staggering 86% of all amputations are the result of minor
injuries to the feet caused by small cuts, pressure from ill-fitting
footwear, improper toenail care and other simple factors.
It follows that every person with diabetes must take special care
of their feet to avoid injuries, infection and possible amputation.
