what is a normal fasting blood sugar reading

A normal fasting blood sugar reading typically falls within the following range:

• Normal: 70 to 99 mg/dL (3.9 to 5.5 mmol/L)

Fasting blood sugar is measured after not eating or drinking anything except water for at least 8 hours. If your fasting blood sugar is consistently outside this range, it may indicate prediabetes or diabetes. Here’s a quick reference:
