what's a good glucose number

A good glucose number depends on whether you're checking your blood sugar while fasting or after eating. 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

For people with diabetes, the American Diabetes Association (ADA) recommends an A1C level of less than 7%, which corresponds to an average blood glucose level of about 154 mg/dL. However, individual targets may vary based on your health condition and doctor's advice.
