What is a Normal Blood Sugar Range? Specific Numbers

Understanding the specific numbers that define a "normal" blood sugar range is crucial. Here’s a breakdown of typical targets for individuals without diabetes. Please note: these are general guidelines, and individual targets may vary; always consult with your healthcare provider.

  • Fasting Blood Sugar: This is your blood sugar level after not eating for at least 2 hours (typically overnight).
    • Normal: Less than 100 mg/dL (5.6 mmol/L)
    • Prediabetes: 100-125 mg/dL (5.6-6.9 mmol/L)
    • Diabetes: 126 mg/dL (7.0 mmol/L) or higher (on two separate tests)
  • 2-Hour Postprandial (After Meals): This is your blood sugar level 2 hours after the start of a meal.
    • Normal: Less than 140 mg/dL (7.8 mmol/L)
  • A1C: This test reflects your average blood sugar levels over the past 2-3 months.
    • Normal: Below 5.7%
    • Prediabetes: 5.7% - 6.4%
    • Diabetes: 6.5% or higher

Blood Sugar Ranges for Individuals with Diabetes

For individuals diagnosed with diabetes, target blood sugar ranges are typically adjusted to maintain optimal health and prevent complications. These ranges can vary based on factors like age, overall health, and individual treatment plans. Common targets include:

  • Fasting: 80-130 mg/dL (4.4-7.2 mmol/L)
  • 2-Hour Postprandial: Less than 180 mg/dL (10.0 mmol/L)
  • A1C: Generally, below 7%, but individual goals may be more stringent.
