The normal range of blood glucose is different for different people. For normal people, the normal range of fasting blood glucose is 3.9mmo/L~6.1mmo/L, and the 2-hour postprandial blood glucose should be less than 7.8mmo/L. For diabetic patients, the general range of fasting blood glucose is 4.4mmo/L~7.0mmo/L, and the 2-hour postprandial blood glucose should be less than 10mmo/L. If you find elevated blood glucose levels, you should go to a regular hospital in a timely manner to get a clear diagnosis under the guidance of a medical professional. If diagnosed with diabetes, generally need to be through diet therapy, exercise therapy, drug therapy and other ways of comprehensive treatment. As far as possible, blood glucose control will be up to standard. In addition to diabetes, infection, stress and other conditions may also lead to elevated blood glucose levels, which can be clarified under the guidance of a professional endocrinologist.
