what is the normal blood sugar range for adults

The normal blood sugar range for adults varies 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 Blood Sugar (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)

These ranges are for non-diabetic adults. If you have diabetes, your target ranges may differ, and you should consult your healthcare provider for personalized goals.
