If the blood sugar can be controlled by simply taking insulin, it is possible not to take medication. If the blood sugar control is not good, oral hypoglycemic drugs may need to be added, and the specifics need to follow the doctor’s instructions. The treatment plan for diabetes is individualized and not identical. Whether the patient takes insulin or oral medication depends on the patient’s condition. If the patient’s pancreatic function is relatively poor, this patient is suitable for insulin. If insulin can control blood sugar smoothly, there is no need to take additional hypoglycemic drugs. If the blood sugar control is not smooth with insulin alone, glucose-lowering drugs such as metformin and glibenclamide can be added. If the patient has obvious insulin resistance and the pancreatic islet function is still OK, these patients prefer oral hypoglycemic drugs for treatment. In addition to the application of drug therapy, diabetes patients, diet and life regulation is also very important, it is recommended that diabetic patients eat low glycemic index food, and every day to moderate exercise, keep a happy mood. Insulin and hypoglycemic drugs, depending on the patient’s blood glucose control, it is recommended to consult a doctor and follow the doctor’s instructions for blood glucose control.
