Diabetic ketoacidosis (DKA) is one of the most serious complications of diabetes mellitus (DM) that is prone to occur in children with type 1 DM (T1DM). We report a 17-year-old overweight girl who was treated with multiple oral antihyperglycemic drugs under the initial impression of type 2 DM (T2DM). Nevertheless, severe euglycemic DKA happened after the additional prescription of sodium-glucose cotransporter 2 inhibitors for two months. Consequently, T1DM was diagnosed on the basis of insulinopenic status in glucagon test and the presence of islet autoantibodies. This case highlighted the importance of precise classification before diabetes treatment in adolescence. A literature review is aimed to help clinicians differentiate various types of DM more specifically in clinical practice
