• Diabetes during a previous pregnancy
• Excess body weight (especially around the waist)
• Family history of diabetes
• Given birth to a baby weighing more than 9 pounds
• HDL cholesterol under 35 mg/dL
• High blood levels of triglycerides, a type of fat molecule (250 mg/dL or more)
• High blood pressure (greater than or equal to 140/90 mmHg)
• Impaired glucose tolerance

Persons from certain ethnic groups, including African Americans, Hispanic Americans, Asian Americans, and Native Americans, have a higher risk for diabetes.

Everyone over 45 should have a blood sugar (glucose) test at least every 3 years. Regular testing of blood sugar levels should begin at a younger age, and be performed more often if you are at higher risk for diabetes.
