A blood sugar level of 109 mg/dL can be interpreted as follows:

  • Fasting Blood Sugar (before eating):

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

    A fasting blood sugar of 109 mg/dL falls into the prediabetes range, indicating slightly elevated blood sugar levels. It’s important to monitor your levels and consult a healthcare provider for further evaluation.

  • Postprandial (after eating):

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

    If 109 mg/dL is measured after eating, it is considered normal.

Next Steps:

  • If fasting, consider lifestyle changes like diet and exercise to lower your risk of developing diabetes.
  • Regular monitoring and follow-up with a healthcare provider are recommended.
