How high is the blood sugar on an empty stomach? How to test?

Blood sugar is an important part of health examination, and reasonable monitoring of healthy people is helpful to early detection of diabetes; Regular monitoring of blood sugar in diabetic patients helps to know whether blood sugar is under control and whether it is necessary to adjust the hypoglycemic scheme. So, how high is blood sugar to be considered hyperglycemia? What level can be diagnosed as diabetes? Next, medical science will analyze it for you.

Fasting blood glucose and 2-hour postprandial blood glucose are the main items of blood glucose monitoring. Diabetes patients need to monitor glycosylated hemoglobin at the same time. First, let's take a look. How to judge whether these indicators are normal?

Fasting blood sugar: the normal range of blood sugar measured after fasting for more than 8 hours is 3.9-6.1mmol/L. When the blood sugar is between 6. 1-6.9mmol/L, it is pre-diabetes, and when the blood sugar reaches 7.0 mmol/L, it can be diagnosed as diabetes. 2 hours postprandial blood sugar: the blood sugar measured 2 hours after eating the first bite, the normal range is 4. 4-7。 8 mmol/L, when the blood sugar reaches the following level, it is pre-diabetes and when it reaches11.1mmol/L, it can be diagnosed as diabetes. Glycosylated hemoglobin: an indicator reflecting the overall control of blood sugar in recent three months, with a normal range of 4. 0 %-6。 0%, more than 6. 0% is abnormal. At present, glycosylated hemoglobin has not been included in the diagnostic criteria of diabetes. Both fasting blood glucose and postprandial blood glucose are within the normal range, indicating that the body has better ability to secrete insulin, higher sensitivity to insulin and stronger ability to regulate blood sugar. However, human metabolism is interrelated. Even if blood sugar is normal, if other metabolic indicators are abnormal, the risk of developing type 2 diabetes is higher. Therefore, friends with normal blood sugar should also pay attention to the following indicators:

When the blood sugar is higher than the normal range, that is, the fasting blood sugar reaches 6. 1mmol/L, and/or the 2-hour postprandial blood sugar reaches 7.8mmol/L, that is, the fasting blood sugar is lower than 7.0mmol/L, and/or the 2-hour postprandial blood sugar is lower than1kloc-0/.65438. Pre-diabetes is a dangerous signal of diabetes, and if blood sugar rises further, it will progress to diabetes; If pre-diabetic patients are accompanied by abdominal obesity, elevated blood pressure, elevated triglycerides and decreased high-density lipoprotein cholesterol, they should also be diagnosed as metabolic syndrome, and the risk of developing type 2 diabetes in the future is higher. However, pre-diabetic patients have the opportunity to reverse diabetes through reasonable intervention. At this stage, patients do not need to start medication for the time being, and lifestyle intervention is the main way to control sugar, with emphasis on controlling diet, exercise and weight.
