If you are middle age, inactive,
and overweight you may have prediabetes, meaning your blood glucose (sugar)
levels are higher than normal. Since they haven’t yet reached the levels
required for an official diabetes diagnosis and a need for insulin (the hormone
required for the metabolism of foods and the regulation of blood sugar
levels)—there’s still time to reverse your course down a dangerous and
potentially deadly road to poor health.
All About Prediabetes
Prediabetes is a common condition:
According to the Centers for Disease Control (CDC), in 2010, an estimated one
out of three adults (and one out of two of those 65 and older) had prediabetes.
Worse, most people with prediabetes are not even aware they have it. Without
intervention, many of these people will go on to develop type 2 diabetes.

Functional physician Mark Hyman, MD,
has his own name for this condition: diabesity, which he says describes the
continuum from optimal blood sugar balance to full-blown diabetes. In his book,
The Blood Sugar Solution, Hyman writes: "Nearly all people who are
overweight (over 70 percent of adult Americans) already have prediabetes and
have significant risks of disease and death." Even if an individual has
normal blood sugar, he or she may still have diabesity. Hyman calls diabesity
the single biggest global health epidemic of our time.
Signs and Symptoms
One of the most common symptoms of
prediabetes is darkened areas of the skin (acanthosis nigricans). These usually
appear on the neck, armpits, elbows, knees, or knuckles. Other potential
symptoms include increased thirst, frequent urination, fatigue, and blurred
vision. Unfortunately, says diabetes expert Amber Taylor, MD, most individuals
with prediabetes don’t have symptoms and don’t know they should be tested.
Testing for the Condition
There are a few tests for
prediabetes and diabetes:
The A1C Test measures the average
glucose (sugar) in your blood stream over the previous two to three months. A
score of 5.7 to 6.4 percent can be categorized as prediabetes.
The Fasting Blood (or Plasma)
Glucose Test measures blood sugar after at least eight hours of fasting; 100 to
125 mg/dl (milligrams per deciliter of blood) indicates prediabetes.
The Oral Glucose Tolerance Test
(OGTT) checks your blood sugar levels before and after you drink a specially
formulated (and very sweet) drink. It measures how well your body processes
sugar. Results of 140 to 199 ml/dl indicate your blood sugar is elevated.
Good News for People With
Prediabetes
On the bright side, prediabetes
responds very well to lifestyle changes, even if you have other diabetes risk
factors, such as family history. Taylor
says simple adjustments such as improving your diet and adding exercise to your
day can make an enormous difference. Look at it as an opportunity to improve
your health and help prevent a future diagnosis of type 2 diabetes.
