Prediabetes

Type 2 diabetes does not strike without warning. Prediabetes, also known as impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) , precedes the condition by months, years, and sometimes even decades. As the name suggests, prediabetes is defined by blood glucose levels that are higher than normal, but not high enough to indicate diabetes. The actual clinical criterion for a diagnosis of prediabetes is blood glucose level of 110 to 125 mg/ dl (6.1 to 6.9 mmol/l), as determined by a fasting blood glucose test, or a two hour glucose level rising to 140 to 199 mg/dl (7.8 to 11.0 mmol/l). Prediabetes is a signal that without some healthy lifestyle changes, you are most certainly on the path to full fledged type 2 diabetes. And having prediabetes is a danger in itself. It increases the likelihood of stroke and heart disease by 50 percent, and may also be associated with an increased risk of colon cancer.

E Alert

One of the reasons for the boom in type 2 diabetes is the widening of waistbands and the trend toward a more sedentary lifestyle in the United States and other developed countries. In America , the shift has been dramatic; in the 1990s alone, obesity increased by 61 percent and diagnosed diabetes by 49 percent.

Am I at Risk?

Known risk factors for both prediabetes and type 2 diabetes include:

Being overweight or obese.

Family history of diabetes.

Low HDL cholesterol (less than 35 mg/dl, or 1.9 mmol/l) and high triglycerides (higher than 250 mg/dl).

High blood pressure (consistent reading of 140/90 mmHg or higher).

E Fact

According to the U.S. Department of Health and Human Services, an estimated 16 million Americans have prediabetes almost as many as are diagnosed with type 2 itself. Many are unaware of their condition. Worse, almost 6 million Americans who have full blown diabetes remain undiagnosed.
