  • Diabetes: 126 mg/dL or higher

• Postprandial Blood Sugar (2 hours after eating):

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

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

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

These ranges are general guidelines. Always consult your healthcare provider for personalized advice.
