What fasting blood sugar level indicates prediabetes?

The fasting blood sugar level that indicates prediabetes is between 100 and 125 mg/dl. This range is important for recognizing the increased risk for developing type 2 diabetes. The classification is based on established medical guidelines, which define normal fasting blood sugar levels as less than 100 mg/dl. When blood sugar levels fall within the 100 to 125 mg/dl range, it signifies that glucose metabolism is impaired but not yet at the level that would diagnose diabetes. Levels of 126 mg/dl or higher are indicative of diabetes. Recognizing prediabetes is crucial for implementing lifestyle interventions aimed at preventing the progression to diabetes.
