what is a good range for glucose

A good range for blood glucose levels depends on whether you are fasting, have eaten recently, or have diabetes. Here are 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%–6.4%
  • Diabetes: 6.5% or higher

Always consult your healthcare provider for personalized targets, especially if you have diabetes or other health conditions.
