For diabetic patients, whether this disease can achieve a cure is a matter of great concern. Here we can reply with certainty that more than 99% of diabetic patients do not have the possibility of cure, and this possibility is based on the current level of medicine. There are many types of diabetes, type 1 diabetes is definitely impossible to cure, these patients are absolutely lack of insulin, even if the effect of treatment is achieved through islet transplantation or pancreas transplantation, but it is impossible to cure this disease from the root. The possibility of curing type 2 diabetes is also very low, because it is difficult to completely correct either the relative lack of insulin or the insulin resistance itself. The possibility of cure for patients with special types of diabetes is relatively high, because special types of diabetes, as the name implies, are those in which the cause of the diabetes can be clarified, especially those with genetic mutations, and with the development of medical technology, it is possible to achieve a cure for these special types of diabetes.
