Diabetes is a disease that affects how the body makes use of glucose,
a form of sugar, which is our major source of energy. We acquire
glucose from the food we eat and when it gets into our bloodstream, our
pancreas generates a hormone known as insulin that assists the sugar to
get inside our cells for use as energy. However, if one has diabetes
mellitus, the body either cannot create sufficient insulin, which is the
cause of type 1 diabetes, or the insulin no longer works as expected
because the cells are no longer sensitive to it, which typifies type 2
diabetes. Either way, the glucose is unable to enter the cells normally,
and thus the concentration of sugar in the blood increases, which
brings about several symptoms.
Causes of diabetes
The cause of diabetes depends on the type. Type 1 diabetes mellitus,
for instance is genetic in nature, and then set off by particular
infections, just like Coxsackie virus. The mechanism is unclear, however
it is thought that after the infection, the body's own immune system
damages the cells where insulin is made. Type 2 DM on the contrary is
caused primarily by lifestyle and genetic factors.
Some health conditions and medicines can also trigger diabetes.
Exocrine pancreatic disorders and use of glucocorticoids, for instance,
can bring about diabetes.
Symptoms of diabetes
Type 1 and Type 2 diabetes patients can go through the same symptoms.
Disproportionate urination, disproportionate thirst, and excessive
hunger are the three basic symptoms of diabetes mellitus. Loss of weight
may also be present. Sustained high blood glucose can also result to
microvascular changes that can lead to blurring of vision and prolonged
wound healing. Symptoms may develop quickly for type 1 diabetics, while
they typically develop slowly among type 2 diabetes patients.
Treatment of diabetes
Unfortunately, diabetes mellitus cannot be cured. Nevertheless, it
can be managed to minimize its effects in your life. Treatment involves
insulin injections, oral hypoglycemics, changes in lifestyle, and annual
or regular checkups. Left untreated or if poorly managed, complications
like loss of vision, amputation, and multiple organ injury may happen
sooner than hoped.
Can diabetes be prevented?
For type 1 DM, the answer is, unfortunately, no. For type 2 diabetes
mellitus however, being a disease of affluence, can be averted by
keeping a healthy weight. This will entail making healthier food
choices, like reducing intake of simple sugars, and making sure that you
get ample exercise. Staying away from vices including smoking and
drinking are also crucial since these activities can speed up the
development of of complications.
