what is high fasting blood glucose

High fasting blood glucose refers to elevated blood sugar levels after a period of not eating (typically 8 hours or more). According to the American Diabetes Association (ADA), the following ranges are used to diagnose prediabetes and diabetes:

• Normal: Below 100 mg/dL
• Prediabetes: 100–125 mg/dL
• Diabetes: 126 mg/dL or higher

High fasting blood glucose can indicate insulin resistance or diabetes. It is important to monitor and manage these levels to prevent complications such as heart disease, kidney damage, and nerve issues. Consult your healthcare provider for personalized advice and treatment options.
