Diabetic ketoacidosis in type 2 diabetes: a rare but deadly complication

Background: Diabetic ketoacidosis (DKA) is a complication of diabetes mellitus resulting from the absolute or relative deficiency of circulating insulin, defined by derangements in serum pH, bicarbonate, glucose, and ketone. Although less common, 4–29% of type 2 diabetes mellitus (T2DM) can present with DKA. 1 This case highlights the importance of recognising DKA as a rare but important complication in T2DM and the subtle postmortem findings that may accompany it.
