what is a normal fasting blood sugar number

A normal fasting blood sugar level is typically between 70 to 99 mg/dL (milligrams per deciliter). This measurement is taken after not eating or drinking anything except water for at least 8 hours.

Here’s a quick reference table:

Blood Sugar Level (mg/dL) Category

70 - 99 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.
