The diagnostic criteria for diabetes are the presence of diabetic symptoms, such as excessive drinking, excessive urination, excessive food and weight loss. As well as to meet the fasting blood glucose 7 ≥ mmol / l, or 2 hours after the meal blood glucose ≥ 11.1 mmol / l, or random blood glucose ≥ 11.1 mmol / l, or glycated hemoglobin ≥ 6.5%, any of the above can be diagnosed as diabetes mellitus.
