The normal blood sugar range for adults varies depending on whether the measurement is taken fasting or after eating. Here are the general guidelines:
- Fasting Blood Sugar (before eating): 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 Test (average over 2–3 months): Below 5.7%
These ranges may vary slightly depending on individual health conditions and guidelines from different medical organizations. Always consult with a healthcare provider for personalized advice.
