what blood sugar is normal

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 Test (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.
