what is normal fasting blood sugar range

The normal fasting blood sugar range for most adults is between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L). Here’s a breakdown of blood sugar ranges:

Blood Sugar Level (mg/dL) Category

Fasting blood sugar is typically measured after not eating for at least 8 hours. If your levels are consistently outside the normal range, consult a healthcare provider for further evaluation.
