Introduction: Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. Less prevalent is euglycemic DKA (eDKA)—DKA with serum glucose less than 200 mg/dL; however, it is increasing in frequency with the introduction of sodium glucose cotransporter 2 (SGLT-2) inhibitors for treatment of type 2 diabetes.

Case Report: We report a case of SGLT-2 inhibitor-associated eDKA presenting with concurrent acute pericarditis.

Discussion: Our case suggests that the cause of eDKA can be multifactorial when decreased oral intake occurs in the setting of an acute cause of physiologic stress.

Conclusion: Prompt recognition of eDKA in the emergency department may allow earlier diagnosis and treatment directed at one or more of its underlying causes.
