Euglycemic ketoacidosis is an acute, life-threatening emergency that is characterized by euglycemia, metabolic acidosis, and ketonemia. It is a well-recognized adverse event in diabetic patients taking sodium-glucose cotransporter-2 inhibitor (SGLT-2 inhibitor). However, there is limited data on SGLT-2 inhibitor-related euglycemic ketoacidosis in non-diabetic patients. ⋯ Our objective is to comprehensively revisit the pathophysiology of euglycemic ketoacidosis associated with SGLT-2 inhibitors and the risk factors for the condition, review the available data, and summarize the reported cases of euglycemic ketoacidosis in non-diabetic patients on SGLT-2 inhibitors. Our literature search identified five articles with six cases of euglycemic ketoacidosis in non-diabetic patients who were on SGLT-2 inhibitors for heart failure with reduced ejection fraction. The common risk factor in five out of the six cases was decreased oral intake due to acute illness, fasting, or a perioperative state.
