Type 2 diabetes is a very common disease in clinical practice. Poorly controlled blood glucose may cause symptoms of polyuria and fatigue in mild cases, while severe complications may bring about kidney, fundus, vascular and neurological problems in severe cases. Although there are numerous drugs available, including stem cell transplantation, there is still no cure. But not being curable does not mean that it cannot be well controlled. As long as one receives regular treatment as early as possible, lowers blood sugar to the normal range as early as possible, reduces glucotoxicity, protects one’s islet function, and helps repair insulin function, a small percentage of patients are able to discontinue medication for a period of time after treatment and experience a honeymoon phase performance similar to type 1 diabetes, and can be assured of good blood sugar through lifestyle intervention alone. And just because it can’t be cured doesn’t mean it’s terminal. Some studies have shown that long-term blood glucose control is up to standard and the life expectancy of diabetics is the same as that of normal people. Therefore, once the elevated blood glucose is found, you should immediately go to a regular hospital for examination to clarify the diagnosis of diabetes, and receive standardized and individualized treatment under the guidance of a doctor as soon as possible, regularly monitor blood glucose under the control of diet and exercise, and adjust the glucose-lowering program in a timely manner.
