what should fasting blood glucose be

Fasting blood glucose levels are an important indicator of your metabolic health. Here are the general guidelines:

• Normal: 70–99 mg/dL (3.9–5.5 mmol/L)
• Prediabetes: 100–125 mg/dL (5.6–6.9 mmol/L)
• Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests

Fasting blood glucose is typically measured after not eating for at least 8 hours. If your levels are consistently high, it may indicate prediabetes or diabetes. Consult your healthcare provider for a proper diagnosis and management plan.
