what's the normal sugar level for adults

Normal blood sugar levels for adults vary depending on whether you are fasting or have recently 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)
• Hemoglobin A1C (average over 2–3 months): Less than 5.7%

These ranges are considered normal for most adults. However, individual targets may vary based on health conditions, age, and other factors. Always consult with a healthcare provider for personalized advice.
