Violent type 1 diabetes is usually not curable, and what medicine can do at present is to use insulin to help type 1 diabetics control their blood glucose, to stabilize it throughout the day, and to reduce the occurrence of complications. The main feature of fulminant type 1 diabetes is acute and irreversible damage to pancreatic β-cells, rapid increase in blood glucose, and basically normal glycosylated hemoglobin. Once diagnosed, patients with type 1 diabetes will be treated with diabetic ketoacidosis and given rehydration fluids and intravenous insulin therapy, and insulin will be used for intensive treatment immediately after the correction of the diabetic ketoacidosis. Although patients with type 1 diabetes are currently required to use insulin for life to control blood glucose. However, if the blood glucose control is roughly stable and close to the normal level, they can live and study as normal people, can delay the emergence of diabetes complications, and improve the quality of life of patients. Therefore, although the disease cannot be cured, patients should follow the doctor’s instructions and actively control blood sugar.
