Normal blood sugar levels vary depending on the time of day and whether you have eaten. 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 Test (average over 2–3 months): Below 5.7%
These ranges are for adults without diabetes. If you have diabetes, your target levels may differ, and you should follow your healthcare provider's recommendations.
