what is a normal sugar reading

Normal blood sugar levels vary depending on the time of day and whether you have eaten recently. Here are general guidelines for blood sugar levels:

• Fasting Blood Sugar (before meals): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
• Random Blood Sugar: Typically less than 140 mg/dL (7.8 mmol/L)

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