what is a normal fasting sugar level

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

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

Fasting blood sugar levels are measured after not eating or drinking anything (except water) for at least 8 hours. Here’s a breakdown of the ranges:

Blood Sugar Level (mg/dL) Category
