Background: Iatrogenic hypoglycemia is an unintended, though common, occurrence in individuals with diabetes. There is a clear association between hypoglycemia exposure and an increase in mortality in individuals with type 2 diabetes (T2DM). It is well-established that recurrent hypoglycemic episodes impair the counterregulatory hormone responses; however, it is yet to be determined if in T2DM there are more global effects of hypoglycemia on autonomic control of cardiovascular function (baroreflex sensitivity, BRS), as has been shown in healthy individuals. This is a clinically relevant knowledge gap as decreases in BRS are pro-arrhythmogenic and associated with decreases in mortality in individuals with diabetes.
