Numbers about Your Heart

High blood pressure, or hypertension, is associated with a higher risk of diabetes, so it's a good idea to work with your doctor to make sure your blood pressure is within the preferred range -- ideally under 120/80 for those under age 65.
Cholesterol is equally important. Ask your doctor to check your cholesterol and make sure your total cholesterol is under 200 mg/dL, your LDL is under 130 mg/dL, and your HDL (or "good" cholesterol) is at least 40 mg/dL for men and 50 mg/dL for women.
