For normal people, fasting blood glucose ≥6.1mmol/L is considered high; two hours after meal blood glucose ≥7.8mmol/L is considered high, and random blood glucose ≥11.1mmol/L is considered high; for diabetic people, generally fasting blood glucose ≥7mmol/L is considered high, and two hours after meal blood glucose ≥10mmol/L is considered high.
Blood glucose values are different in different states, so it is impossible to generalize how much blood glucose is considered high. Normal blood glucose standards for people are fasting blood glucose 3.9~6.1mmol/L, 2 hours after meal blood glucose <7.8mmol/L, random blood glucose <11.1mmol/L. If you have diabetes typical "Three Types of Diabetes", you will be considered as high.
If there are the typical "three more and one less" symptoms of diabetes, i.e., excessive drinking, excessive eating, excessive urination, and wasting, and satisfy any one of the fasting blood glucose 7 ≥ mmol/l, or 2-hour postprandial blood glucose ≥ 11.1 mmol/l, or random blood glucose ≥ 11.1 mmol/l, or glycated hemoglobin ≥ 6.5%, then diabetes can be diagnosed.
If there are no symptoms of diabetes, two plasma glucose levels are required to confirm the diagnosis.
Patients diagnosed with diabetes are generally required to have a fasting blood glucose of less than 7 mmol/l, a two-hour postprandial blood glucose of less than 10 mmol/l, and a glycosylated hemoglobin of less than 7%. According to the patient's age, comorbidities and comprehensive judgment and adjustment. If the above criteria are met, it is generally considered that blood glucose control is good and not high.
If blood glucose is abnormal, one should go to a regular hospital for relevant examinations. For those with elevated blood glucose levels, active lifestyle intervention is needed, and if diabetes is present, medication is taken if necessary.
