what should a blood sugar reading be

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 (before eating, in the morning): 70–99 mg/dL (3.9–5.5 mmol/L)
• 2 hours after eating: Less than 140 mg/dL (7.8 mmol/L)
• Random (anytime): Less than 140 mg/dL (7.8 mmol/L)

For individuals with diabetes, target blood sugar levels may differ and should be determined by a healthcare provider. Typical targets are:

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

Always consult your doctor for personalized targets based on your health condition.
