Diabetes is the result of a combination of genetics and environment. As lifestyles change, exercise decreases, and obesity increases, so does the prevalence of diabetes. Diabetes is a lifelong disease and there is still no definite cure for diabetes in the world. But although diabetes cannot be cured, it can be well controlled in the long term. Diabetic patients must do a good job with the basic treatment of diet and exercise. Under the guidance of a doctor, oral medication or insulin should be used to control blood glucose, and regular monitoring of blood glucose, glycated hemoglobin and complications should be done to slow down the development of complications.
