Criteria for Pre-Diabetes Updated

The Expert Committee on the Diagnosis and Classification of Diabetes has lowered the fasting blood sugar level to diagnose Pre-Diabetes.  Pre-Diabetes is a condition in which blood sugar is higher than normal but not high enough to diagnose diabetes.  Pre-Diabetes increases risk for type 2 diabetes in the future.

Here is what has changed:

Updated Diagnosis Criteria

• A fasting blood sugar of 100 - 125 mg/dl now indicates Pre-Diabetes. 
• A normal fasting blood sugar is now less than 100 mg/dl.

Previous Diagnosis Criteria

• A fasting blood sugar of 110-125 mg/dl indicated Pre-Diabetes.
• A normal fasting blood sugar was less than 110 mg/dl.

A fasting blood sugar of 126 mg/dl or more still indicates diabetes.  In addition to increased risk for diabetes, those with Pre-Diabetes are also at increased risk for heart disease.  Pre-Diabetes is also associated a condition known as metabolic syndrome.  Metabolic syndrome is characterized by high blood pressure, dyslipidemia (disordered blood fats including decreased HDL (good) cholesterol levels and/or elevated triglycerides), elevated fasting blood sugar, and centralized obesity (or abdominal obesity, apple body shape).

The good news...

A reduction of body weight, following a healthy meal plan, exercise, and some medications can help to delay or prevent the development of diabetes. Talk with your doctor about your diabetes and heart disease risks.
