what are the normal blood sugar levels

Normal blood sugar levels vary depending on the time of day and whether you have eaten recently. Here are the general guidelines for normal blood sugar levels:

• Fasting Blood Sugar (before meals): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial Blood Sugar (1-2 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 levels may differ, and you should consult your healthcare provider for personalized goals.
