Diabetes is also called digital disease from the point of view of diagnosis. We diagnose diabetes whenever fasting blood sugar or postprandial blood sugar reaches a certain level. Usually the current criteria are fasting blood glucose over 7 mmol/L and postprandial blood glucose over 11.1 mmol/L. You may be concerned, am I diabetic and how do I diagnose diabetes? This question is actually very simple. From the point of view of diagnosis, diabetes can be called a digital disease, as long as fasting blood sugar reaches a certain level, or postprandial blood sugar reaches a certain level, it is diagnosed as diabetes. This threshold is in fact artificially defined, but it is defined on the basis of the general definition of this level is closely associated with the occurrence of complications. Of course, this diagnostic criteria has also changed a lot, when I first became a doctor, the requirements were broader at that time. At that time, the diagnostic criteria were that fasting blood glucose should be greater than 7.8 mmol/L and post-load or post-prandial blood glucose should reach 1.1 mmol/L before we could diagnose diabetes. Now it is more strict, as long as the fasting blood glucose is more than 7 mmol/L and the post-load blood glucose is 11.1 mmol/L, we will diagnose diabetes, so it is relatively easy to diagnose diabetes.
