Kay  /  Australia The term fasting glycemia refers to your blood sugar level after you've fasted overnight or for at least 8 hours. High blood sugar (hyperglycemia) may indicate diabetes. The amount of sugar in your blood naturally fluctuates but within a narrow range. A normal level following an overnight fast is between 70 and 100 milligrams of glucose per deciliter of blood (mg/dL). If your blood sugar level measures between 101 and 125 mg/dL, you have impaired fasting glucose, also called prediabetes. This means you're at high risk of developing diabetes and should take steps to control your blood sugar levels. If your blood sugar level is 126 mg/dL or greater on two separate occasions, you have diabetes.
