Blood sugar levels naturally fluctuate throughout the day, and occasional highs and lows are common. According to common clinical guidelines in Singapore, the target blood glucose range before meals or during fasting is typically 4.0 to 7.0 mmol/L.

Two hours after a meal, it's normal for glucose levels to rise. The recommended post-meal range is usually 5.0 to 10.0 mmol/L. If your A1C targets are not being met, your doctor may advise keeping post-meal glucose within 5.0 to 8.0 mmol/L to improve overall glycemic control.

Morning Blood Glucose Levels

Morning glucose levels may be slightly lower, as the body has been fasting overnight and activity levels are low. After breakfast, glucose levels generally rise back into the normal range.

If your morning readings are consistently too high or too low, consult your doctor for advice on how to adjust your treatment or lifestyle to stay within your target range.

Note: Your target glucose range should be set by your healthcare provider based on your individual health condition.
