Is measuring blood glucose at 5 a.m. accurate?
Disease description:
After my grandfather was discharged from the hospital for diabetes, his doctor instructed him to monitor his blood glucose daily and pay attention to any changes. However, my grandfather has a habit of morning exercise, so he wakes up very early each day. Is it accurate to measure his blood glucose at 5 a.m.?

Under normal circumstances, fasting blood glucose monitoring in the morning requires approximately 10 hours of fasting to ensure accurate results. For example, if the last meal is consumed around 7:00 PM, testing at approximately 5:00 AM yields a relatively accurate reading. It is essential to maintain blood glucose levels within the normal range. Poor glycemic control significantly increases the risk of complications, posing substantial harm to overall health.
