If you’re over age 30 and overweight, you need your blood sugar checked, say health experts calling for earlier screenings and more aggressive action against diabetes. Why? Because significant cardiovascular disease can develop years before the actual onset of diabetes. New recommendations say if you have any risk factors for diabetes—excess weight, an inactive lifestyle, a family history of diabetes or being of African-American, Hispanic or American Indian descent—you should begin regular screenings at age 30. What’s more, if your blood sugar is too high, you should begin drug therapy to control blood sugar right away in addition to making lifestyle changes. This advice comes from a recent conference of the American College of Endocrinology and the American Association of Clinical Endocrinologists. While more than 20 million Americans already suffer from diabetes, another 60 million have pre-diabetes, a condition that, left untreated, develops into diabetes.
