Diabetes
Long term spinal cord injury (SCI) and diabetes? According to
some researchers the two go together like coffee and cream, like
Bonnie and Clyde. Dr. Bill Bauman, for example, has studied diabetes
extensively in spinal cord injured people. He writes that as many
as 20 percent of spinal cord injury survivors have adult-onset
diabetes; an even larger percentage, he says, don't have symptoms,
yet their laboratory bloodwork findings suggest their bodies do
not use insulin properly. What does this mean for SCI survivors?

What Is Diabetes?
Diabetes is a chronic disease in which the body doesn't make enough
insulin – a hormone from the pancreas – or somehow doesn't use
it correctly. As a result, glucose or blood sugar that is normally
carried to the body's cells for fuel instead builds up in the
bloodstream. This extra glucose – called high blood sugar – can
damage all organs of the body, especially the eyes, kidneys, and
blood vessels.
Type I (insulin-dependent) diabetes starts in childhood or young
adulthood, and requires daily insulin injections. Type II diabetes
– which often is called adult-onset diabetes – usually occurs
in adults over 40 and accounts for 95% of all diabetes cases.
This type is of most concern to SCI survivors. While it usually
can be controlled through diet and exercise, some people also
need oral medications or insulin injections.
Symptoms:
Early symptoms are dehydration, excessive urination, extreme thirst,
increased appetite and weight loss. However–perhaps unfortunately–you
may have no symptoms at all.
Long-term Implications:
In addition to diabetic coma and insulin shock, which can be life-threatening,
diabetes is a grab bag of complications. Atherosclerosis–hardening
of the arteries–can damage the heart or affect circulation in
feet and legs, sometimes requiring amputation. Kidney, eye, and
peripheral nerve damage can also occur. The best news about diabetes
is that it is controllable.
Risk Factors:
By far the most important risk factor is age. Others are a family
history of the disease,
being overweight, and inactivity. Diabetes is slightly more prevalent
in women and nonwhite people . Estimates of incidence for diabetes
in the over-40 population vary from 2 to 16%.
The SCI Factor:
So how do you fit into the picture? Where does the additional
risk, if any, come from?
- SCI alters the body’s metabolism. Frequently muscle mass is lost
below the level of injury, and at the same time, fat tissue may
increase throughout the body–both above and below the injury site.
These two factors alter metabolism enough to affect how insulin
is used by the body.
- Inactivity further impairs glucose tolerance and causes abnormal
insulin levels.
- Illnesses like influenza and pneumonia–and even injuries–may cause
blood glucose swings, adding to the risk created by SCI itself.
- The older you get, the greater your chances of developing diabetes
are. Though everyone gets old, some researchers and clinicians–and
more than a few survivors themselves–feel that people with SCI
get old faster than nondisabled people. If aging is accelerated
after SCI, they feel, diabetes may make its appearance sooner.
Diagnosis:
Diagnosis is fairly simple, and is often the result of a routine
urine test. The appearance of the already described symptoms,
high levels of glucose in the urine, or elevated blood sugar levels
on repeated blood tests are the usual indications. Fasting blood
sugar tests are sometimes needed.
Treatment:
Doctors treat diabetes by keeping blood glucose levels as close
to normal as possible
through diet, exercise, oral medications and, when necessary,
added insulin. Other than working to lessen risk factors, there
is no way to actually end the disease. But major improvement is
possible, and you play the key role.
If you have diabetes, get involved in a good diabetes education
program. Most people learn to check their own blood sugar levels
and to adjust their diet, exercise and insulin doses. They can
also read their body’s built-in warning signs or symptoms of changes
in the insulin-glucose balance. Your doctor can teach you these
things or refer you to a class. A large local hospital may have
a nurse educator who specializes in diabetes education, and printed
information is easily found in libraries or through your local
diabetes association.
Diet:
Diets are custom-tailored for each individual, based on sex, activity
level, disease progression and your own physician’s philosophy
on how precisely blood sugar levels should be controlled. They
should be followed carefully. If you have a friend with diabetes,
do not assume his or her diet will work for you.
Regardless of whether or not you must follow a strict diet, there
still are some general dietary guidelines:
- Always eat at a regular time; avoid skipping meals; avoid sweets
and desserts.
- Limit fats–especially saturated ones–in order to minimize the
risk of circulatory complications.
- If you will be using alcohol on a particular day, you may have
to decrease your fat and carbohydrate intake to accommodate it.
- Some early studies suggest that high fiber diets help decrease
glucose levels.
Exercise:
Exercise and physical activity help. When aerobic capacity improves,
so does glucose
tolerance. If you have never exercised, if you have other medical
or orthopedic problems, or even if you don’t know where to start,
it would be a good idea to work with your physician or therapist.
If you are using insulin to manage your diabetes, it’s not just
a good idea to work with your doctor, it’s essential.
Avoiding Complications:
Be especially careful in watching for complications. Most involve
the circulatory system, creating risk of visual changes, cardiac
problems and amputations. Regular vision checkups and monitoring
your cardiac status are crucial.
Exercise, infection and fever can affect metabolism and insulin
needs, so changes in treatment may be needed. Learn how to anticipate
and respond to these changes.
Watch your skin closely. Foot care is vital–wear loose socks,
soft shoes that fit well, and keep your nails trimmed. Danger
signs: skin breakdown that won’t heal, changes in the color and
texture of your toes, and swelling in the ankles. Don't ignore
them.
Stress:
Some researchers feel that stress aggravates diabetes. Find ways
to relax, such as hobbies, trips, relaxation tapes, or–best of
all–kill two birds with one stone and start that aerobic exercise
program.
Getting Help:
Look for professionals who understand SCI as well as diabetes,
starting with your SCI
center. If you can't find one doctor well versed in both issues,
find two who are willing to work together. Your ultimate resource,
though, is yourself. Learn as much as you can. Take control of
your care and speak up for yourself.

Parting Thoughts:
Yes, there probably is a higher incidence of diabetes among SCI
survivors. But many of the reasons for that increase are as much
from how SCI affects your lifestyle–through diet, weight gain
and decreased activity–as they are from the actual physiological
change. Because SCI survivors have the same causes and risks as
nondisabled people, they can benefit from the same lifestyle changes,
such as diet, weight, exercise, and stress management. Careful
management of diabetes generally has excellent results.
