A fasting blood glucose level of 7.1 mmol/L has already exceeded the normal range, but this does not mean serious health problems will occur immediately.
The normal fasting blood glucose range should be between 3.9-6.1 mmol/L. A fasting blood glucose level of 7.1 mmol/L exceeds the normal range, and if multiple measurements consistently show elevated levels, or are accompanied by typical symptoms such as excessive thirst, frequent urination, increased appetite, and weight loss, it is likely that diabetes is already present, a situation that requires attention.
However, if an elevated fasting blood glucose level of 7.1 mmol/L occurs only occasionally, it may simply reflect temporary fluctuations in blood glucose and does not necessarily indicate diabetes. For example, excessive food intake the previous evening, insufficient sleep, emotional stress, or excessive fatigue can all lead to elevated blood glucose levels. Patients are advised to seek medical attention promptly, control blood glucose through lifestyle adjustments and, when necessary, medication, and prevent complications.
In daily life, it is recommended to monitor blood glucose regularly, maintain close communication with a physician, develop an individualized treatment plan, and stabilize blood glucose levels.
