what a normal blood sugar range

Normal blood sugar ranges vary depending on when you last ate. Here are the general guidelines:

• 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. Always consult your healthcare provider for personalized advice.
