Is a fasting blood glucose level of 6.2 mmol/L serious?

Fasting blood glucose of 6.2 mmol/L has not yet reached the diagnostic criteria for diabetes and is generally not serious, but should be taken seriously as it falls within the range of abnormal blood glucose.

According to the diagnostic criteria for diabetes, fasting blood glucose ≥7.0 mmol/L can be diagnosed as diabetes; while 6.1 mmol/L ≤ fasting blood glucose <7.0 mmol/L is referred to as impaired fasting glucose, which belongs to the prediabetic stage. Therefore, a level of 6.2 mmol/L falls within the prediabetic stage, typically not serious, but indicating abnormal glucose metabolism, which may progress to diabetes if no intervention is taken.

Improving diet and increasing physical activity can help regulate blood glucose levels. It is recommended to reduce intake of high-sugar and high-fat foods, and increase dietary fiber intake, such as eating more vegetables and whole grains. Additionally, engaging in moderate aerobic exercise, such as brisk walking or jogging, can help improve the body's sensitivity to insulin, thus assisting in lowering blood glucose levels.

If repeated blood glucose monitoring still shows elevated levels or if other diabetes-related symptoms appear, such as increased thirst, frequent urination, or weight loss, it is recommended to seek timely medical consultation. The doctor will develop a personalized treatment plan, including possible pharmacological treatment, based on the patient's specific condition.
