PG - e28514 LID - 10.7759/cureus.28514 [doi] LID - e28514 AB - Diabetic ketoacidosis (DKA) is a triad of uncontrolled hyperglycemia, metabolic acidosis, and increased total body ketone concentration. It is a well-known manifestation of type 1 diabetes mellitus (T1DM). However, it can also be the first presentation of type 2 diabetes mellitus (T2DM). This subtype of diabetes shares the characteristics of both T1DM and T2DM and is called 'Flatbush diabetes,' also known as 'ketosis-prone T2DM.' This article highlights the importance of early identification of ketosis-prone T2DM (KPD). We describe two cases of African American men with no past medical histories who presented with unproved DKA as the first presentation of T2DM requiring initial intensive insulin therapy, which was gradually withdrawn with the addition of metformin. Both patients are currently insulin independent for more than 15 months. It is an essential clinical entity to recognize as insulin independence positively impacts the quality of life and decreases the economic burden on the health care system.
