Early detection of diabetes requires attention to the following points: 1. If you belong to a high-risk group of diabetes, you need to increase the number of blood glucose tests accordingly; 2. If you have symptoms of diabetes, such as “three more and one less”, itchy skin, or skin wounds that are difficult to recover, you should go to the hospital and have your blood glucose tested in time to detect diabetes and treat it early; 3. For people over 45 years old, if you have a family history, it is recommended that you monitor your blood glucose every year; if you do not have a family history or diabetes-related accidents, you can reduce the number of tests appropriately, once every three years.
