Don’t wait to be diagnosed with type 2 diabetes to protect your vision.
Diabetic retinopathy is one of the severe complications
of diabetes. Just like the other complications of
diabetes, it’s caused by damage to the blood vessels as
a result of high blood sugars. In this case the blood
vessels of the retina in the eye are the target. It’s
the most common eye disease among people with diabetes
and a leading cause of blindness. Retinopathy is a
progressive condition that at first may have no
symptoms. About 45% of people with diabetes have some
degree of retinopathy.
To
avoid any of the complications of diabetes or slow their
progression, your goal should be to maintain blood sugar
levels as close to normal as possible. Since
carbohydrates are the foods that primarily elevate blood
sugar it makes sense to consume carb foods with the
lowest glycemic response.
Unfortunately, the
American Diabetes Association doesn’t
think along those lines. The ADA even allows sugar to be
included in a diabetic diet routine. They recommend
calorie restriction which in the long run allows too
many carbs and a reliance on too many meds to manage
blood sugar. A recent study attempting to accomplish
tight blood sugar control using combinations of meds led
to a higher death rate than in those patients given less
aggressive therapies. In my view the lesson of this
result is to minimize the need for aggressive drugs and
their dangerous side effects especially as people age
and are less able to handle numerous meds. You can do
this by controlling both the quality and quantity of
carbs to address blood sugar. Many people on Atkins have
better blood sugar results without meds than they did
before beginning the Atkins Lifestyle while on meds.
The
ADA’s goal for adequate blood sugar control is an A1C
less than 7. This means an average blood sugar of about
170 or less. Even an A1C of 6 means an average blood
sugar of about 140. Based on a new paper these levels
are likely to be too high, putting vulnerable blood
vessels in the eye and perhaps in the entire body at
risk.
Even
pre-diabetes has its risks
A paper
published in the March 1, 2008 edition of Lancet found
that more then 60% of retinopathy cases occurred in
patients with fasting blood sugars (FBS) below 126mg/dl.
An FBS of 126 or above is one of the diagnostic
criterion for diabetes. This means that damage to blood
vessels in the eye can occur well before the diagnosis
of diabetes is made. An FBS of 100 to 125 mg/dl is
called pre-diabetes. There are millions of undiagnosed
people with diabetes and many millions more at risk for
it.
This
study should give everyone one more reason to practice
aggressive prevention by cleaning up their diets and
normalizing weight. This is especially urgent if you
have a family history of diabetes or if you’re a
candidate for metabolic syndrome. To find out if you or
someone you love has metabolic syndrome review the
presentation found
here.
The
findings in this paper have not surprisingly led to
discussions about what they mean. One researcher felt
that these findings require a re-evaluation of the
diagnostic criteria for diabetes.
Regardless of what decisions are eventually reached,
common sense dictates that people who are overweight or
obese, have a family history of diabetes, had
gestational diabetes when pregnant, those who can’t
control their carb intake, people with a sedentary
lifestyle or have metabolic syndrome, or those with
reactive hypoglycemia have a wonderful opportunity to
make one of the most important investments of their
lives. Control the quality and quantity of carbs and
protect not only your waistline but your vision as
well.
