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.
