Diabetes is a chronic metabolic disease with elevated blood sugar as the main cause. The danger of diabetes lies in the various acute and chronic complications arising from elevated blood sugar. At present, diabetes is still a lifelong disease worldwide and can only be controlled but not cured, so all propaganda aimed at curing diabetes may be a scam. But diabetes, although not curable, can be kept under good control for a long time. Diabetes is treated with oral hypoglycemic drugs or insulin on the basis of diet and exercise. Diabetic patients must be treated with hypoglycemic drugs from the time they are diagnosed with diabetes, if diet and exercise cannot control blood sugar well, so hypoglycemic drugs can be taken for a long time and must be taken for a long time. If the blood glucose rises and oral hypoglycemic drugs fail in the course of diabetes treatment, you can switch to insulin treatment under the guidance of your doctor.
