Which scenarios are commonly associated with euglycemic DKA?

• A. Metformin
• B. Sulfonylureas
• C. Insulin
• D. SGLT2 inhibitors, prolonged fasting, or pregnancy

Answer: (D)

Euglycemic DKA happens when you have ketoacidosis with normal or only mildly elevated blood glucose. The glucose level isn’t the driver here; the key is that insulin deficiency or relative insulin deficiency and increased counterregulatory hormones promote ketone production, but some circumstances keep glucose from rising as high as in typical DKA. In people taking SGLT2 inhibitors, the drug class causes the kidneys to dump glucose into the urine, which lowers blood glucose. At the same time, insulin levels can fall and glucagon levels can rise, which promotes fat breakdown and ketone formation. The result is significant ketosis and acidosis with glucose that may stay normal or only modestly elevated. Prolonged fasting lowers insulin relative to glucagon, shifts metabolism toward fat use, and drives ketogenesis in the liver. Since glucose intake is limited, blood glucose can remain in a normal range while ketosis progresses, creating euglycemic DKA. Pregnancy also creates a predisposed state: hormonal changes induce insulin resistance, and if there is reduced intake or dehydration, ketosis can develop more readily. The net effect is a higher risk of ketoacidosis with normal or only mildly raised glucose. So these scenarios are commonly linked to euglycemic DKA because they can promote ketone production and acidosis without the expected marked hyperglycemia, which is the hallmark not-to-miss clue in this condition.
