INS and type 1 diabetes mellitus: We conclude that i) to meet goals of type 1 diabetes care insulin treatment, food intake and exercise have to be handled in concert and the respective recommendations implemented, ii) this need is helped by simple standardization of lifestyle, which easily also could be implemented at home, iii) compliance with rules of insulin treatment in T1D care cannot be replaced by arbitrary medication with add-on glucose-lowering drugs, and iv) costs of necessary patient education can be considerably reduced if offered at a DRC instead of acute hospitals.
