Context In most patients presenting with hypoglycemia in emergency departments, the etiology of hypoglycemia is identified. However, it cannot be determined in approximately 10% of cases. Objective We aimed to identify the causes of unknown hypoglycemia, especially adrenal insufficiency. Methods In this cross-sectional study, we evaluated the etiology of hypoglycemia among patients in our emergency department with hypoglycemia (plasma glucose level Results There were 528 cases with hypoglycemia included [52.1% male; median age 62 years (range 19-92)]. The majority [389 (73.7%)] of patients were using antidiabetes drugs. Additionally, 33 (6.3%) consumed alcohol; 17 (3.2%) had malnutrition; 13 (2.5%), liver dysfunction; 12 (2.3%), severe infectious disease; 11 (2.1%), malignancy; 9 (1.7%), heart failure; 4 (0.8%), insulin autoimmune syndrome; 3 (0.6%), insulinoma; 2 (0.4%) were using hypoglycemia-relevant drugs; and 1 (0.2%) suffered from non-islet cell tumor. Rapid ACTH tests revealed adrenal insufficiency in 32 (6.1%). In those patients, serum sodium levels were lower (132 vs 139 mEq/L, P Conclusion The frequency of adrenal insufficiency as a cause of hypoglycemia was much higher than what we anticipated. When protracted hypoglycemia of unknown etiology is recognized, we recommend that the patient is checked for adrenal function using a rapid ACTH test. |
