Type 2 diabetes cannot be completely reversed to normal, but it can be remitted, and active intervention can lead to remission of type 2 diabetes. Diabetes mellitus is a group of diseases caused by a long-term combination of genetic and environmental factors, ranging from insulin resistance to progressive insulin insufficiency, and most patients require lifelong medication. However, in the early stages of type 2 diabetes, the damage to pancreatic function is not serious, and after active treatment, pancreatic function can be restored, which can make diabetes remission. Patients with diabetes need to take medication as prescribed by the doctor, strengthen self-management, rationalize their lifestyle and monitor their condition. Regular and appropriate exercise in daily life should be carried out in a gradual manner and persisted for a long time. Type 2 diabetes patients should be treated under the guidance of their doctors according to their own conditions.
