INS and diabetes mellitus: Beta-blocker use has been associated with increased rate of severe hypoglycemia in adults with diabetes.35 Especially in people with IAH, beta-blockers may less often be prescribed because clinicians may fear the effect they can have on attenuating the symptoms of hypoglycemia.2 However, a recent study suggested that beta-blocker use was not related to hypoglycemia unawareness, or burden in hospitalized high-risk insulin-requiring people with diabetes.36 The use of a glucose sensor was higher in participants with IAH.
