When a diabetic patient has a blood glucose of about 9.0 mmol/L, it is necessary to clarify when that blood glucose value is the blood glucose value; if it is the blood glucose 2 hours after a meal, it is within the control target range, and it is sufficient to continue to use the previous treatment plan. If there are diabetic complications or medications that do not control blood glucose, insulin therapy is required. If the fasting blood glucose is around 9.0mmol/L, you can first use some hypoglycemic drugs, such as metformin, etc., as prescribed by the doctor. If the postprandial blood glucose is around 9.0mmol/L, the blood glucose control is better, but you need to follow the doctor’s instructions for regular use of medication, such as acarbose, etc., and regular monitoring of blood glucose levels. Patients diagnosed with diabetes are advised to seek timely medical treatment, under the guidance of the doctor, according to the type of diabetes, whether or not obesity, etc. to choose the appropriate treatment plan, and follow the doctor’s instructions to take glibenclamide and other drugs for glucose-lowering treatment. When there are complications of diabetes, such as hypertonic hyperglycemia syndrome, diabetic ketoacidosis, poor glycemic control, etc., the drug can not promote insulin secretion, you need to follow the doctor’s instructions to use insulin for treatment, insulin can quickly promote the cellular absorption and conversion of glucose, reduce blood glucose. Diabetic patients, it is recommended that under the guidance of the doctor, choose the appropriate glucose-lowering treatment program to avoid causing complications.
