The U.S. Preventive Services Task Force (USPSTF) is recommending that adults between ages 40 to 70 who are overweight or obese be screened for abnormal blood glucose. The guidelines are considered a way to lower the risk of developing heart diseases and type 2 diabetes.  Having abnormal blood glucose metabolism is a risk factor for heart disease and could progress to diabetes. The Task Force reviewed the available research and found evidence to support screening for abnormal blood glucose before it can progress to diabetes. The Task Force previously did not factor weight into its recommendations and instead recommended screening for type 2 diabetes in asymptomatic adults with high blood pressure in 2008.
