what are normal blood glucose levels

Normal blood glucose levels vary depending on when you last ate. Here are the general guidelines:

• Fasting (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• 2 hours after eating: Less than 140 mg/dL (7.8 mmol/L)

For people with diabetes, target blood glucose levels are typically:

• Fasting: 80–130 mg/dL (4.4–7.2 mmol/L)
• 2 hours after eating: Less than 180 mg/dL (10.0 mmol/L)

These ranges may vary based on individual health conditions and recommendations from your healthcare provider.
