There is no cure for diabetes mellitus, but some patients can be treated surgically to keep their blood glucose within the normal range and may be able to reverse diabetes mellitus. Usually diabetes mellitus is a disease of increased blood glucose due to genetic factors, environmental factors, defects in the autoimmune system, etc., resulting in absolute or relative insufficient secretion of insulin or impaired utilization of insulin, which leads to disturbances in carbohydrate, protein and fat metabolism. Typical clinical symptoms such as excessive drinking, excessive eating, excessive urination, and weight loss will occur, requiring regular blood glucose monitoring and treatment. Usually, diabetic patients need to choose hypoglycemic drugs or insulin injection for treatment under the guidance of doctors. For example, glibenclamide and gliclazide can promote insulin secretion from pancreatic β-cells to control blood sugar. Secondly, you can choose metformin, which can reduce the output of glucose from the liver after taking, so as to achieve the effect of lowering blood sugar. If blood glucose is not controlled after treatment with hypoglycemic drugs or is complicated by other diseases, insulin injections are needed. It is usually recommended that diabetic patients regularly monitor their blood glucose and medication, and when poor blood glucose control occurs, it is recommended that they consult a doctor in time to adjust their treatment plan under the guidance of the doctor.
