what is a high fasting blood sugar

Fasting blood sugar (glucose) levels are measured after not eating for at least 8 hours. The following ranges are used to interpret 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

A fasting blood sugar level of 126 mg/dL or higher is considered high and may indicate diabetes. If your fasting blood sugar is consistently high, it’s important to consult a healthcare provider for further evaluation and management.
