High-risk individuals include those with a family history of diabetes, overweight individuals (BMI greater than 25), those with heart disease, high blood pressure, high triglyceride levels, low HDL levels, gestational diabetes, delivered a baby weighing more than 9 lbs, polycystic ovarian syndrome, or impaired glucose tolerance. African Americans have a 60% higher rate of developing diabetes and Hispanics have a 90% increased risk compared to Caucasians. High-risk individuals should get a fasting blood sugar test beginning at age 45, but new recommendations suggest screening as early as age 30 for those at high risk.
