When exceeding 10 millimoles, pay attention to the changes and seek medical attention if necessary. When exceeding 13.9 millimoles, hospitalization is required.

Pay attention to changes when it is below 3.9. If it continues to decrease, seek medical attention. If it is below 2.8, seek medical attention immediately.

Postprandial blood glucose normal value
