what is the average blood sugar reading

The average blood sugar reading can vary depending on whether you are measuring it at a single point in time or over a period of time. Here are some general guidelines:

• Normal Blood Sugar Levels:

  • Fasting (before meals): 70–99 mg/dL
  • Postprandial (2 hours after eating): Less than 140 mg/dL

• A1C Test:

  • The A1C test measures your average blood sugar levels over the past 2–3 months. The results are given as a percentage:
    • Normal: Below 5.7%
    • Prediabetes: 5.7% to 6.4%
    • Diabetes: 6.5% or above

• Estimated Average Glucose (eAG):

  • The A1C percentage can also be converted to an estimated average glucose (eAG) level, which is measured in mg/dL. For example:
    • A1C of 6%: eAG of 126 mg/dL
    • A1C of 7%: eAG of 154 mg/dL
    • A1C of 8%: eAG of 183 mg/dL

It's important to note that individual blood sugar targets may vary based on factors such as age, overall health, and whether you have diabetes. Always consult with your healthcare provider to determine what is normal and healthy for you.
