what is a good glucose number

A good glucose number depends on when you measure it and your overall health. Here are general guidelines for blood glucose levels:

• Fasting (before meals): 70–99 mg/dL (normal), 100–125 mg/dL (prediabetes), 126 mg/dL or higher (diabetes).
• 2 hours after eating: Less than 140 mg/dL (normal), 140–199 mg/dL (prediabetes), 200 mg/dL or higher (diabetes).
• A1C (average over 3 months): Below 5.7% (normal), 5.7–6.4% (prediabetes), 6.5% or higher (diabetes).

Always consult your healthcare provider for personalized targets based on your medical history and condition.
