It is generally accepted that the more reasonable intensive treatment in clinical practice is insulin pumps and multiple insulin injections. Diabetes treatment guidelines indicate that premixed insulin analogs may also be an option for short-term intensive insulin therapy. In fact, intensive therapy focuses on bringing blood glucose control to normal by all means, so some studies have shown that for newly diagnosed diabetics, short-term intensive therapy with basal insulin combined with oral medications does not show significant differences in glycemic control or restoration of pancreatic islet cell function when compared to insulin pumps. However, studies have also shown that intensive therapy can significantly improve the effects of glucotoxicity in diabetic patients, contributing to symptomatic improvement and recovery, especially in those with high blood glucose levels, and achieving better clinical symptomatic improvement. Therefore, patients who meet the indications for intensive insulin therapy are also eligible for insulin pumps, or multiple daily insulin injections, as well as premixed insulin analogs, or basal insulin combined with oral medications. So, intensive is not just insulin treatment is considered, no matter what means, the purpose of intensive is to control blood glucose to the normal target, and the course of treatment is generally need to be 2 to 3 months time is appropriate.
