what is fasting blood sugar

Fasting blood sugar (FBS) refers to the level of glucose in your blood after you have not eaten for at least 8 hours. It is commonly measured to assess blood sugar control and diagnose conditions like diabetes or prediabetes.

Normal Ranges for Fasting Blood Sugar:

• Normal: Less than 100 mg/dL
• Prediabetes: 100 to 125 mg/dL
• Diabetes: 126 mg/dL or higher on two separate tests

Why is it important?

• It helps diagnose diabetes or prediabetes.
• It provides insight into how well your body manages blood sugar levels over time.

How is it tested?

• A blood sample is taken after an overnight fast (usually 8-12 hours).
• It is often part of routine health checkups or diabetes management plans.

If your fasting blood sugar is high, consult your healthcare provider for further evaluation and management.
