Is there a diabetes cure?
Is
there a diabetes cure? The usual answer of course is no.
But let’s look a little more closely.
A
diabetes cure would indeed be a remarkable thing.
Diabetes, particularly Type 2, has become a worldwide
epidemic. In the United States and the United Kingdom,
almost one fifth of the population already have diabetes, and
as countries in the rest of the world adopt a more Western diet
and way of living, the same tendency is being seen elsewhere,
with India and China experiencing an explosion in the
appearance of diabetes in their populations.
In
Type 1 diabetes, where the insulin secreting cells in the
pancreas are destroyed, it seems that a cure would be
impossible. However this is not necessarily the case and
there are a number of possibilities being studied at the moment
which might offer a genuine cure. Firstly, some patients
can be offered pancreatic transplantation so that they once
again have functioning pancreases and their diabetes is
cured.
Other approaches which may also
offer a cure include transplantation of individual islet cells
or of stem cells (immature cells which have the potential to
develop into a whole lot of other types of cells), which can
take over insulin production from the natural failing beta
cells in someone with Type 1 diabetes.
Also, there are some experimental
treatments being studied which work against the body’s immune
processes continuing to destroy the beta cells of the
pancreas. Of particular interest here is treatment with
the BCG vaccine, which is normally used to treat
tuberculosis. Other people have suggested that the nerves
supplying the pancreas may play some part in the causation of
diabetes, and there is some experimental evidence that
treatments with drugs affecting these nerves can help the beta
cells regenerate. All these studies are of course in
their very early stages, but they do offer some hope the
future.
In
relation to Type 2 diabetes, which makes up 95% of total, there
are also some real hopes. There are two main approaches
here, both of which have been shown to be effective in
practice.
The
first is simply reducing the amount of carbohydrate in the
diet. In the past many people were treated in this way,
but nowadays the recommendations from the major diabetes
associations is to eat a relatively high carbohydrate and low
fat diet because of the fear of heart disease. In fact,
the evidence for this approach is not good, and the pendulum is
beginning to swing back towards using diets with a much lower
carbohydrate content. Some people have claimed that if
you reduce the carbohydrate intake enough, diabetes will simply
go away in quite a lot of people.
The
other main approach which has attracted interest is based on
the theory that Type 2 diabetes may be caused by artificially
processed facts known as trans fats. These do not occur
naturally, but are widely used in the food industry.
There is some evidence to suggest that these should be
eliminated entirely from the diet and replaced with naturally
occurring fats and oils known as cis fats, particularly of the
omega-3 type which occur in sources such as flax oil, hemp oil
and fish oils.
A
diabetes cure may not be around the corner, but certainly there
are hopes that some or all of the approaches described above
may help to reduce the damage caused by diabetes, which is
rapidly becoming the commonest cause of death
worldwide.
