what is a normal blood sugar

Normal blood sugar levels vary depending on when you last ate. Here are the general guidelines:

• Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• 2 Hours After Eating: Less than 140 mg/dL (7.8 mmol/L)
• Random Blood Sugar: Typically less than 125 mg/dL (6.9 mmol/L) in a non-diabetic person

These values may vary slightly depending on the lab and individual health conditions. Always consult your healthcare provider for personalized advice.
