what are good blood glucose numbers

Normal blood glucose levels vary depending on whether you are fasting or have eaten recently. Here are the general guidelines:

• Fasting Blood Sugar (before eating):

  • Normal: 70–99 mg/dL
  • Prediabetes: 100–125 mg/dL
  • Diabetes: 126 mg/dL or higher

• Postprandial (2 hours after eating):

  • Normal: Less than 140 mg/dL
  • Prediabetes: 140–199 mg/dL
  • Diabetes: 200 mg/dL or higher

• A1C Levels (average over 2–3 months):

  • Normal: Below 5.7%
  • Prediabetes: 5.7% to 6.4%
  • Diabetes: 6.5% or higher

These ranges may vary slightly depending on individual health conditions and guidelines from healthcare providers. Always consult your doctor for personalized targets.
