Conclusions: The greater insulin requirement in SGLT2i DKA compared to non-SGLT2i DKA may be explained by the greater proportion of precipitating intercurrent illnesses and demographic differences in SGLT2i DKA, highlighting that SGLT2i DKA (predominantly comprising T2D) and non-SGLT2i DKA (predominantly comprising T1D) represent distinct clinical entities. Here, INS is linked to type 1 diabetes mellitus.
