Frequent nocturia in diabetic patients may be greatly related to poor control of blood glucose levels. It is recommended that patients choose the appropriate glucose-lowering program under the guidance of the doctor. Along with diet therapy and exercise therapy, they can take glucose-lowering medication as prescribed by the doctor, such as metformin, acarbose, etc., for treatment, and subcutaneous injection of insulin can be used if necessary to keep blood glucose within the normal range as much as possible. Typical symptoms of diabetic patients are three more and one less, such as drinking more, eating more, urinating more and losing weight. The patient’s frequent nocturia is most likely caused by unstable blood sugar control. However, it is not excluded that urinary tract infection, diabetic nephropathy and other disease factors lead to frequent nocturia. It is recommended that diabetic patients with frequent nocturia should go to the hospital in time, and under the guidance of the doctor to carry out standardized treatment, do not blindly use other drugs, so as not to delay the condition and cause adverse consequences.
