what is a safe glucose level

A safe blood glucose level varies depending on whether you are fasting, have eaten recently, or have diabetes. Here are 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:
  • 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. Always consult your healthcare provider for personalized targets.
