what should glucose level be

Normal blood glucose levels vary depending on whether you are fasting or have recently eaten. Here are the general guidelines:

• Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
• A1C (average over 2–3 months): Below 5.7% (normal), 5.7–6.4% (prediabetes), 6.5% or higher (diabetes)

For individuals with diabetes, target levels may vary based on individual health conditions and treatment plans. Always consult your healthcare provider for personalized recommendations.
