what should blood sugar numbers be

Normal blood sugar levels vary depending on the time of day and whether you have eaten. 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 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)

These ranges may vary depending on individual health conditions and treatment plans. Always consult your healthcare provider for personalized targets.
