what is a good fasting blood sugar reading

A good fasting blood sugar reading typically falls within the following ranges:

• Normal: 70–99 mg/dL (3.9–5.5 mmol/L)
• Prediabetes: 100–125 mg/dL (5.6–6.9 mmol/L)
• Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests

Fasting blood sugar is measured after not eating for at least 8 hours. If your levels are consistently outside the normal range, consult a healthcare provider for further evaluation and management.
