Effect of adrenergic agents on postgastrectomy hypoglycemia.

Abstract

Reactive hypoglycemia was documented in ten postgastrectomy patients by a control oral glucose tolerance test (OGTT). Nine patients experienced nausea, flushing, and fatigue during the first hour of the test. Neuroglycopenic or adrenergic symptoms of hypoglycemia occurred in eight patients two to five hours after oral glucose. The oral administration of phenylephrine elixir, 15 mg., thirty minutes before a repeat OGTT, significantly raised thelowest plasma glucose from 37.5 +/- 2.8 mg./dl. to 45.2 +/- 3.8 mg./dl. (p less than 0.05) but did not affect the occurrence of either the early or the late symptoms. In contrast, propranolol, 10 mg., raised the lowest plasma glucose from 37.5 +/- 2.8 mg./dl. to 57 +/- 5.2 mg./dl. (p less than 0.02) and prevented the occurrence of early and late symptoms. Neither peak nor total plasma insulin levels were affected by either drug. The rate of glucose utilization, as determined by intravenous glucose tolerance tests, did not significantly change after the oral administration of either drug. It is concluded that propranolol ameliorated the symptoms and chemical hypoglycemia after oral glucose and merits more detailed study as a long-term therapy for this disorder.
