Blood sugar levels are typically measured using a blood glucose meter or through laboratory tests. Here’s how you can compute or interpret blood sugar levels:
-
Fasting Blood Sugar (FBS): Measured after not eating for at least 8 hours.
- Normal: Less than 100 mg/dL
- Prediabetes: 100–125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Postprandial Blood Sugar (PPBS): Measured 2 hours after eating.
- Normal: Less than 140 mg/dL
- Prediabetes: 140–199 mg/dL
- Diabetes: 200 mg/dL or higher
-
Hemoglobin A1C (HbA1c): Reflects average blood sugar over the past 2–3 months.
- Normal: Below 5.7%
- Prediabetes: 5.7%–6.4%
- Diabetes: 6.5% or higher
For accurate results, always follow your healthcare provider’s instructions and use calibrated devices.
