Diabetes: What the Diagnosis
Means
"If you just found out you have
diabetes, you probably have a lot of questions and you may
feel a little uncertain. It may help to know you're not alone.
In the United States, nearly 16 million people have diabetes.
Most of these people lead full, healthy lives. One of the best
things you can do for yourself is to learn all you can about
diabetes. "
What is
diabetes?
Your body
changes most of the food you eat into glucose (a form of
sugar). Insulin, a hormone produced by the pancreas, allows
glucose to enter all the cells of your body and be used as
energy. Diabetes is a disease that occurs when a person’s body
doesn’t make enough insulin or can’t use insulin properly.
When you have diabetes, the sugar builds up in your blood
instead of moving into the cells. Some, but not all, of the
excess sugar is carried out of your body (through urine), and
the energy is wasted.

There
are two types of diabetes. Type 1 occurs when the body doesn’t
produce any insulin. People with type 2 diabetes either don’t
produce enough insulin or their cells ignore the insulin.
Nearly 95% of people with diabetes have type 2.
How can I help myself stay healthy if I
have diabetes?
Although
diabetes can’t be cured, you can live a long and healthy life.
The single most important thing you can do is control your
blood sugar level. You can do this by eating right,
exercising, maintaining a healthy weight and, if needed,
taking oral medicines or insulin.
Eat a
healthy diet. The recommended diet for many people
who have diabetes is very similar to that suggested for people
who don't have diabetes. It's important to eat at least 3
meals per day and never skip a meal.
Exercise. Exercising will help your body use
insulin and lower your blood sugar level.
Maintain a
healthy weight. Losing excess weight and maintaining a
healthy body weight will help you in 2 ways. First, it helps
insulin work better in your body. Second, it will lower your
blood pressure and decrease your risk for heart
disease.
Take your
medicine. If your diabetes can’t be controlled through
diet, exercise and weight control, your doctor may recommend
medicine or insulin. Oral medicines (taken by mouth) can make
your body produce more insulin or help your body use the
insulin it makes more efficiently. Some people need to add
insulin to their bodies. Always take medicines exactly
as your doctor tells you to.
How do I check my blood sugar level?
Your doctor may
suggest that you check your blood sugar level (also called
blood glucose level) at home. Checking your blood sugar level
involves pricking your finger to get a small drop of blood
that you put on a test strip. You can read the results
yourself or insert the strip into a machine called an
electronic glucose meter.
Check your blood
sugar level as often as your doctor suggests. You may need to
check it more often at first, until you get the feel for how
it changes and what makes it change.
What if my blood sugar gets too
low?
People with diabetes
are at risk of hypoglycemia, also called low blood sugar.
Hypoglycemia occurs when the amount of sugar in your blood
drops. The signs of low blood sugar may include having a
headache, sweating, and feeling weak or anxious. Talk to your
doctor about how to treat hypoglycemia. Usually, you can
correct this problem by quickly eating some candy or drinking
some regular (not diet) soda or fruit juice.
What health problems can diabetes
cause?
Diabetes can be a
dangerous and life-threatening disease if you don’t control
your blood sugar level. Over time, high blood sugar levels can
damage your eyes, blood vessels, nerves and kidneys. Here are
some of the problems (also called complications) diabetes can
cause:
Blindness. Diabetes can damage the small blood
vessels in the retina. It is the leading cause of blindness in
people ages 20 to 74.
Heart
disease. People with diabetes are 2 to 4 times more likely
to have heart disease and damage to the blood vessels in the
heart. This increases their risk of heart attack and stroke.
Nerve and
blood vessel damage. Damage to blood vessels in the legs
can limit the supply of blood to the nerves in the legs and
feet. This can make it difficult to feel injuries (such as
foot sores). Damage to the blood vessels can also put you at
risk for infections and sores that don’t heal. In severe
cases, parts of the foot or lower leg may have to be amputated
(removed).
Kidney
disease. Diabetes can damage the small blood vessels in
the kidneys, which then can’t filter out the body’s waste. In
some people, the kidneys stop working completely. These people
require dialysis or a kidney transplant. Dialysis is a
treatment that eliminates wastes in the blood.
The good news is that
diabetic complications can often be prevented by taking care
of yourself, following your doctor’s orders and controlling
your blood sugar level.
