Diabetes is one of the most common chronic diseases. With the improvement of people’s living standard, the aging of the population and the increase of obesity rate, the incidence of diabetes is increasing year by year, and the modern fast-paced and high-intensity and irregular lifestyle makes the risk group of diabetes younger and younger. Diabetes-related advertisements are everywhere in our daily lives, and there is no shortage of false information to interfere with the correct understanding of diabetes. Can diabetes be cured? The overwhelming number of false diabetes advertisements boast of their efficacy and make many people believe that diabetes can be cured, which greatly tempts those patients who “rush to the doctor” and ultimately causes them to suffer financial losses and physical harm. So far, there is no cure for diabetes, and the medical profession has defined diabetes as a lifelong disease. “However, diabetic patients should not be pessimistic and disappointed, but should insist on scientific “living” with diabetes, insist on long-term treatment, cooperate with professional doctors, control blood sugar steadily for a long time, and prevent or delay the occurrence of diabetic complications. The patient should not be pessimistic and disappointed.
