A fasting blood sugar test measures your blood glucose levels after not eating for at least 8 hours. Here are the general guidelines for fasting blood sugar levels:
- Normal: Less than 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher on two separate tests
If your fasting blood sugar is in the prediabetes or diabetes range, it's important to consult with a healthcare provider for further evaluation and management.
