what is 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 blood sugar levels:

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

These ranges are for adults without diabetes. If you have diabetes, your target ranges may differ, and you should follow your healthcare provider's recommendations.
