Pediatric diabetes is usually not curable, but blood glucose can be maintained within the normal range through the use of medication and dietary modifications. Pediatric diabetes is often caused by genetics, autoimmune abnormalities, medication that damages the pancreas, viral infections, etc., resulting in impaired insulin secretion by the pancreas, leading to type 1 diabetes. Due to the lack of treatment, pediatric diabetes is often not completely cured and requires lifelong use of insulin to control blood glucose levels. The treatment of pediatric diabetes requires not only the use of insulin, but also dietary control, reducing the intake of high-sugar foods, increasing the intake of protein foods, and rationally controlling the total energy intake, as well as appropriate exercise, which can help to control blood glucose at normal levels. Therefore, pediatric diabetes should go to the hospital in a timely manner, under the guidance of the doctor for standardized treatment, to avoid a series of complications brought about by elevated blood glucose.
