A fasting blood glucose of 5.6-6.9 mmol/L indicates which condition?

• A. Impaired fasting glucose (prediabetes)
• B. Normal fasting glucose
• C. Diabetes
• D. Hyperglycemia

Answer: (A)

Understanding fasting glucose ranges helps distinguish normal glucose from prediabetes and diabetes. A fasting blood glucose in the range of 5.6 to 6.9 mmol/L is interpreted as impaired fasting glucose, also called prediabetes, meaning blood sugar is elevated above normal but not yet in the diabetic range. Normal fasting glucose is typically below 5.6 mmol/L, while diabetes is diagnosed when fasting glucose reaches 7.0 mmol/L or higher (usually confirmed with a second test). The 5.6–6.9 mmol/L range signals increased risk for developing type 2 diabetes and suggests the need for lifestyle changes to reduce that risk. Hyperglycemia is a general term for high blood glucose and isn’t a precise diagnostic category for this specific range.
