Fasting venous blood glucose 8.8mmol/L is over the normal range for both normal people and diabetic patients and is abnormal. 1. The normal value of fasting venous blood glucose for normal people is between 3.9~6.1mmol/L, so the fasting venous blood glucose of 8.8mmol/L is on the high side, and it is recommended to consult a professional physician for a clear diagnosis. 2. For patients who have been diagnosed with diabetes in the past, the general fasting venous blood glucose needs to be controlled between 4.4~7.0mmol/L, so the fasting venous blood glucose 8.8mmol/L is not up to the control target, and professional doctors can be consulted to adjust the treatment program. Once the blood sugar level is found to be elevated, it is recommended to consult a doctor in time. Patients with abnormal blood glucose need to control their diets, avoid high intake of sugary foods, exercise appropriately, and monitor their blood glucose regularly.
