what's the normal fasting blood sugar level

The normal fasting blood sugar level for most people is between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L). Here's a breakdown of the ranges:

• Normal: 70–100 mg/dL (3.9–5.6 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 levels are typically measured after not eating for at least 8 hours. If your levels are outside the normal range, consult a healthcare provider for further evaluation.
