Common Symptoms of
Diabetes
The symptoms of diabetes can be puzzling. Even the common ones
may not be present in all cases. They may come and go. And the
same symptoms can be produced by other conditions.
Nevertheless, there are a cluster of common circumstances that
tend to mark out the disease.
Unusually frequent urination is one of the classic symptoms
that suggests the possibility of diabetes. One defining
attribute of the disease is excessive glucose levels in the
blood. Either the body produces too little insulin to deal with
it (Type 1 diabetes), or the insulin isn't used correctly (Type
2).
The body attempts to compensate by eliminating the excess
glucose using the urine. The kidneys work at higher than normal
levels to filter out the excess sugar. When they can't remove
enough, the remainder is passed through when other fluids are
eliminated as waste products of metabolic processes.
One result, and an accompanying symptom, is excessive thirst.
The diabetic feels as if he or she is always thirsty, and no
matter how much fluid is taken in it never seems like enough.
That in turn prompts still more urination.
Another common and possible symptom is continual fatigue. Since
insulin isn't performing its role properly by aiding the cells
to take in glucose from the bloodstream, the diabetic may feel
tired. Glucose is the major source of energy for powering an
enormous variety of the body's functions from cell repair to
major muscle movement.
But other body systems can be affected by diabetes and show up
as symptoms.
Blurry vision can result from any number of conditions, even
simple age where it is often just presbyopia. Presbyopia
results from reduced elasticity of the lenses as we age,
leading to a lessened ability to focus. But the cause in the
case of diabetes is very different.
High blood sugar levels reduce fluid in the tissues, including
those of the eye and in particular the lenses. That affects
your ability to focus. When the disease becomes more advanced
it can cause new blood vessels to form in the retina. That
again affects your vision. Though in this circumstance, the
result is more often seeing dark spots or flashing lights, or
rings around room lights.
In some instances, cuts (particularly on the feet) may be
slower to heal when a person has Type 2 diabetes. The reasons
are not yet fully understood, but it is one more indicator. At
the same time, the immune system is affected, leading to a
lowered ability to fight off infection.
Since so many of these symptoms can be (and are) produced by a
number of other conditions, the best course of action if you
suspect you have diabetes is to seek a professional diagnosis.
Simple blood tests can determine with a high degree of
confidence whether or not you do in fact have the disease.
They're relatively painless and most are covered by ordinary
health insurance.
