Fasting blood glucose 11mmol/L is well above the normal range for both normal people and diabetics, and is significantly elevated. 1. The normal value of fasting blood glucose for normal people is between 3.9~6.1mmol/L, so a significant increase in fasting blood glucose 11mmol/L may be caused by diabetes, infection, stress, etc. It is recommended to consult a medical professional for a clear diagnosis. 2. For patients who have been diagnosed with diabetes in the past, the general fasting blood glucose needs to be controlled between 4.4~7.0mmol/L, so the fasting blood glucose 11mmol/L is far beyond the control target, it is recommended to consult a professional doctor to adjust the treatment program. Once the blood glucose level is found to be elevated, it is recommended to consult a doctor in time. Patients with abnormal glucose need to control their diet in their life, avoiding large intake of foods with high sugar content, exercising appropriately, and monitoring their blood glucose on a regular basis.
