Pre-Diabetes Screening Can Improve Health Outcomes

April 12, 2018

Borderline diabetes is a term historically used to describe blood sugars that are elevated, but not yet high enough to confirm a diagnosis of diabetes. The term was not clearly defined and no specific treatment was recommended, so people often were not sure how to manage their condition. In recent years, terminology has changed from borderline to pre-diabetes, which has clearly defined lab values and established treatment recommendations. Screening for pre-diabetes can help identify those at high risk of diabetes so that recommendations can be made to prevent or delay progression to type 2 diabetes.

American Diabetes Association (ADA) estimates that 1 in 3 adults have pre-diabetes. Many are not aware of this condition because it has no obvious symptoms. Risk factors for diabetes include family history, obesity, sedentary lifestyle, and presence of health problems such as high blood pressure, high cholesterol, or history of gestational diabetes. Without identification and treatment, pre-diabetes will often progress to type 2 diabetes within 5 years. The 7 question Pre-Diabetes Risk Test can be taken online at, the official website of the American Diabetes Association. After the test, you get an immediate risk score and discussion of your risk factors, which you can print and take to your healthcare provider. Providers can discuss your risk status, order lab screening tests, and make recommendations for management of pre-diabetes.

Lab tests offered for screening may include an A1C test, fasting blood sugar test, or glucose tolerance test. Each of these tests have different purposes in making a diagnosis. The A1C test estimates blood sugar levels over 2-3 months, while a fasting blood sugar test measures a single point in time. Glucose tolerance testing if often done during pregnancy to evaluate for gestational diabetes, a risk factor for type 2 diabetes later in life. Providers also may offer screenings based on recommendations from the US Preventive Services Task Force, which are based on age and health condition.

Once a pre-diabetes diagnosis is confirmed, current recommendations include lifestyle changes and in some cases, medication. Lifestyle changes often help to delay or prevent the progression to type 2 diabetes. Increasing physical activity and implementing a healthy meal plan can be very effective in achieving a healthy weight. It can be difficult to make these changes without instruction and ongoing support. Our community is fortunate to have many resources to help meet this need. The National Diabetes Prevention Program, established and researched by the Centers for Disease Control, determined that people who successfully complete the program can reduce risk of progressing to type 2 diabetes by at least 58%. Goals of these programs include helping participants achieve weight loss of 5-7% and increasing physical activity to 150 minutes per week. The impact of this can be seen for years! (Ref.
