Recently, an elderly male patient in our clinic reported that he was hospitalized in our department after discovering diabetes six years ago. At that time, his fasting blood glucose was 17, and he was discharged after 2 weeks of intensive insulin pump treatment, and gradually lost 15 kg through diet and exercise. Insight: For newly diagnosed diabetic patients, if they can eliminate high pond toxicity through insulin intensive treatment as early as possible, there is still a good chance that pancreatic B-cell function will be partially restored, and for patients who are more overweight, weight loss will achieve better results. Domestic and foreign data about nearly 60% of new diabetic patients benefit from this treatment. Choice determines outcome!
