Pre-diabetes, Stroke May be Linked

Monday, 11 June 2012 11:46 AM

Tens of millions of Americans with pre-diabetes – higher-than-normal blood sugar levels that put them at risk of becoming diabetic -- may also be more likely to suffer a stroke.
A new study, published in the British Medical Journal, suggests some pre-diabetics may have a “modestly higher risk of future stroke.” The finding, by a team of researchers from the University of California, is based on an analysis of 15 studies involving 760,925 participants.
About 79 million people in the U.S. have pre-diabetes. If left untreated, the condition develops into type 2 diabetes. Pre-diabetics face many of the same health risks as people with diabetes, including high blood pressure, high cholesterol and obesity. The new analysis found those risks also extend to stroke.
Pre-diabetes is generally defined as raised blood glucose levels after a 12-hour fast. A range of 70.2 to 100 milligrams per deciliter is normal, while 100-126 mg/dl is considered a warning sign of pre-diabetes. The researchers found that pre-diabetes -- based on the 1997 American Diabetes Association definition of 110-125 mg/dl -- carried a 21 percent higher chance of stroke.
In 2003, the ADA redefined pre-diabetes as an impaired fasting glucose of 100-125 mg/dl. The researchers said no increased stroke risk was found in studies using this less stringent definition. They added, however, that there may be a 'threshold effect' so that the risk of a stroke begins to rise at or above a fasting glucose level of 110 mg/dl.
