From a medical perspective, evaluating blood glucose levels is a crucial step in diagnosing and managing diabetes and other metabolic disorders. The normal reference range for fasting blood glucose may vary slightly depending on different sources and standards.
The fasting blood glucose range is determined based on measurements of blood glucose concentration after at least 8 hours without food intake, reflecting whether pancreatic cell function is normal. Normal range: fasting blood glucose levels between 3.9 and 6.1 mmol/L are considered normal.
A fasting blood glucose level between 6.0 and 7.0 mmol/L is generally considered higher than normal, also referred to as impaired fasting glucose or abnormal glucose tolerance, which indicates a prediabetic state. Although it does not meet the diagnostic criteria for diabetes, it is recognized as a prediabetic condition.
When fasting blood glucose is greater than or equal to 7.0 mmol/L, and accompanied by typical symptoms of diabetes or repeated measurements of fasting blood glucose consistently greater than or equal to 7.0 mmol/L, a diagnosis of diabetes can be made.
Therefore, in daily life, maintaining a healthy lifestyle, such as balanced nutrition and regular physical activity, can help maintain stable blood glucose levels.
