what is the normal blood sugar reading

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

• Fasting (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)

For people with diabetes, target blood sugar levels are typically:

• Fasting: 80–130 mg/dL (4.4–7.2 mmol/L)
• 2 hours after eating: Less than 180 mg/dL (10.0 mmol/L)

It's important to note that individual targets may vary based on factors like age, overall health, and specific medical conditions. Always consult with your healthcare provider for personalized recommendations.
