How to know if you have prediabetes. It’s D-blog Day!

by James Hubbard, M.D., M.P.H. D-Blog day

D-blog day was created three years ago on November 9 ”to unite diabetic bloggers and create awareness about diabetes“–and we boy do we need awareness.

Almost everyone is affected by diabetes in some way or other.  You either have it or know someone who does.  In the U.S., 7.8 percent of people have diabetes, according to the CDC (PDF download). As many as 1/4 don’t know they have it.  Twenty-five percent of adults have prediabetes, but only 4 percent know it, says the CDC. Talk about needing awareness.

Have you had your sugar checked lately? Is it possible you have prediabetes?  Better read further to make sure.

Prediabetes is diagnosed if your overnight fasting glucose (blood sugar) is between 100 and 126. Above that is true diabetes.  Below is normal.  An ”impaired” glucose-tolerance test, done in a doctor’s office, can also make the diagnosis.

Being prediabetic raises your risk for heart disease to 1.5 times those without it, and your risk of developing full-blown, type 2 diabetes becomes very high.  (Type 2 diabetics’ risk of heart disease is four times normal.)  But here’s the thing.  With prediabetes, losing weight and exercising can keep you from becoming a type 2 diabetic. A large study has shown that exercising for 30 minutes five days a week and losing 5 to 10 percent of weight can cut prediabetics’ risk of diabetes by 58 percent.

But you won’t know to treat it if you don’t know you have it.  Do you know your fasting blood sugar number?
