what's the range for blood sugar

Blood sugar levels vary depending on whether you are fasting, have eaten recently, or have diabetes. Here are the general ranges:

• Normal fasting blood sugar: 70–99 mg/dL (3.9–5.5 mmol/L)
• Normal blood sugar 2 hours after eating: Less than 140 mg/dL (7.8 mmol/L)
• Prediabetes (fasting): 100–125 mg/dL (5.6–6.9 mmol/L)
• Diabetes (fasting): 126 mg/dL (7.0 mmol/L) or higher

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