For people aged 50 years, it is advisable to start diabetes screening early if they have high risk factors for diabetes, such as relatives with a history of diabetes, obesity, etc. For those who have a normal result from the first screening, it is advisable to repeat the screening at least once every three years. For those with pre-diabetic screening results, annual screening is recommended. Those over 50 years of age with reduced physical activity are advised to maintain a low-salt, low-sugar and low-fat diet, engage in appropriate physical exercise, and test their blood glucose on a regular basis. If diabetes has been diagnosed, one should follow medical advice and take glucose-lowering drugs such as glibenclamide and metformin. Diabetes is a big threat to the health of patients, so it is important to be vigilant and strengthen the protection of high-risk groups. Follow your doctor’s instructions for diabetes treatment.
