what is the range for blood sugar levels

Blood sugar levels can 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
• Diabetes (2 hours after eating): 200 mg/dL (11.1 mmol/L) or higher

These ranges may vary slightly depending on the source and individual health conditions. Always consult with a healthcare provider for personalized guidance.
