what is normal fasting blood sugar level

A normal fasting blood sugar level is typically between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L). This is measured after not eating or drinking anything except water for at least 8 hours.

Here’s a quick reference table:

Blood Sugar Level (mg/dL) Interpretation

70–100 Normal
100–125 Prediabetes
126 or higher Diabetes

If your fasting blood sugar is consistently above 100 mg/dL, it may indicate prediabetes or diabetes, and you should consult a healthcare provider for further evaluation.
