When you go to the hospital, the doctor will ask the patient, as he or she is being seen, how long has the blood sugar been high?

At this point, patients who have previously checked their blood sugar will tell the patient that I checked my blood sugar a year ago, if the patient's blood sugar is higher than the diagnostic criteria for diabetes, that is, if the fasting blood glucose is higher than 7.0 mmol/L, and the blood glucose 2 hours after a meal or random blood glucose is more than 11.1 mmol/L, then the doctor will propose to diagnose the patient with diabetes mellitus. "Of course, to confirm the diagnosis, we need to further ask the patient's symptoms, whether there is excessive drinking, excessive urination, thirst, wasting and other symptoms, whether there is blurred vision, skin itching, numbness of the limbs, to improve the preprandial and postprandial glucose, blood glucose profiling, glycated hemoglobin, urine routine and other tests to determine whether the patient can be diagnosed with " Diabetes", if you want to determine which type of diabetes, then you also need to further improve the examination of pancreatic islet function, insulin-related antibody examination, some may also need to carry out genetic testing to determine.

So the diagnosis of diabetes is simple and may be determined by simply two numbers. But the development of diabetes is a long process. From the beginning of the damage to the pancreatic islet function to the development of diabetes, it may take 7-10 years, the process of patients may not have any symptoms, and many patients are also diagnosed with diabetes in the checkup or unintentionally. Of course, there are also some cases of fulminant diabetes, which occur suddenly, and these need to be identified in a number of ancillary tests.

That is why when a doctor writes a medical history, he has to write the time of the onset of the patient's illness according to the patient's description. The reason for the patient to come to the clinic is the chief complaint and the first line written by the doctor when he writes the medical record. The doctor will of course write according to the length of time the patient has been feeling unwell and will not rely on the doctor's experience that the patient's blood glucose was already high when he was obese three years ago and write down that he has had diabetes for three years.

The patient complains of high blood sugar for 1 year, and of course the doctor writes down the history as 1 year, and further tests are needed to determine if diabetes can be diagnosed.The principles that doctors follow in writing medical records are "objectivity, truthfulness, accuracy, timeliness, completeness and standardization".Responsible doctors will usually write medical records very carefully and accurately. After all, with the increase in legal awareness and the improvement of the country's legal system, medical records have become legal documents, and doctors may go to court at any time because of the writing of medical records, so they have to be careful.

This determination of preexisting conditions is inaccurate.

High blood sugar ≠ diabetes

Hyperglycemia≠Diabetes Mellitus。

High blood sugar can be transient, and even when high blood sugar is diagnosed, medication is not immediately recommended, and blood sugar should be lowered through 3-6 months of lifestyle modification sex, and blood sugar levels should be monitored at all times.

Usually after lifestyle changes, if the blood sugar is still abnormal, you can start taking medication drugs or insulin injections, which are part of the history of diabetes from the beginning of taking medication exams.

Of course if a physical examination reveals a much higher blood sugar, along with a high glycosylated hemoglobin and the presence of urinary glucose, a diagnosis of diabetes can also be made immediately.

First, high blood sugar is only counted if it is measured by a hospital doctor. Second, the hospital identifies high blood sugar and determines that it is diabetes. Third, this is the only time to apply for chronic disease procedures.

Incorrect. Medical history consists of many things, if thirst and polyuria for two years and testing blood sugar for diagnosis for one year. Then it is considered a two year history.

That's too general a way to write it. High blood sugar does not necessarily qualify as diabetes. Diabetes can only be diagnosed by a doctor after a blood test and then a doctor's test to meet the indicators of diabetes, and then there are certain types of medications to take and when to take them in order to give a complete medical history.
