how much glucose is normal

Normal blood glucose levels vary depending on whether you are fasting or have recently eaten. Here are the general guidelines:

• Fasting Blood Glucose (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial Blood Glucose (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
• A1C (average over 2–3 months): Below 5.7%

These values are for adults without diabetes. If you have diabetes or prediabetes, your target ranges may differ. Always consult your healthcare provider for personalized advice.
