Since its application in the 1920s, insulin has saved the lives of countless diabetic patients and is one of our powerful weapons in the treatment of diabetes. Regardless of the type of diabetes, it is possible that insulin treatment is needed. Insulin application has now become a very important treatment in the field of diabetes. type 1 diabetes definitely needs insulin treatment because it is insulin deficient, but does type 2 diabetes need insulin treatment? When is insulin more effective? Do you, as a glucose patient, need to start insulin therapy? I will discuss this issue with you: 1. Newly diagnosed type 2 diabetic patients with high blood glucose levels or glycated hemoglobin The International Diabetes Federation recommends that newly diagnosed diabetic patients with a glycated hemoglobin of 9.0% at the onset of diabetes can start combination therapy including insulin; if the glycated hemoglobin is 11.0% intensive insulin therapy should be initiated. Compared with oral hypoglycemic drugs, patients treated with insulin can rapidly reduce this toxic effect due to faster control of the extensive metabolic disorders, avoiding the long-term hyperglycemic toxicity on pancreatic B cells. sustained damage. Some patients with intensive insulin therapy, reasonable diet and exercise therapy, and even after a period of discontinuation of glucose-lowering drugs still have good glycemic control. Of course this group of patients will eventually require medication including insulin as the disease progresses. However, not every newly diagnosed patient must be treated with insulin. For patients with milder disease, diet, exercise and oral medication may be used to achieve the blood glucose standard; while for those patients with excessive obesity, insulin resistance is mostly present and direct insulin treatment is not recommended. For most of the diabetic patients, the prognosis can be improved and the quality of life can be improved by taking active programs to make the blood sugar well controlled and the glycosylated hemoglobin controlled to the standard. The Chinese Medical Association Diabetes Society has set the new control target as glycosylated hemoglobin
