1. Adopt good lifestyle habits. A proper diet and a good lifestyle can minimize the incidence of diabetes. Diabetes is a non-communicable disease, although there are certain genetic factors at play, but the key role is to play the acquired life factors and environmental factors. 2. Regular blood sugar measurement. Blood glucose measurement should be included in the routine medical checkup for middle-aged and elderly people. Anyone who has traces of diabetes, such as abnormal skin sensation, reduced sexual function, poor vision, polyuria, cataracts, etc., should be measured and carefully identified in time to make early diagnosis and gain valuable time for early treatment. 3, early detection of complications.
