title: Alcohol induced changes of carbohydrate metabolism [author's transl].
abstract: It is evident that ethanol by itself or one of its metabolites produces alterations in transport, metabolism and disposition of carbohydrates. Ethanol acts via changes in the redox state of co-factors; e.g. ethanol-induced hypoglycemia is due, partly, to the inhibition of hepatic gluconeogenesis by ethanol as a consequence of the increased NADH2/NAD ratio in patients whose glycogen stores are already depleted. On the other hand, hyperglycemia has also been described in patients with alcoholism. Although its mechanism is still obscure, abnormal hormonal secretion of insulin, catecholamines and glucocorticoids has been incriminated. Finally, structural changes of the liver and pancreas such as cirrhosis and pancreatitis produced by chronic alcohol consumption should also be considered as pathogenetic factors in a variety of clinical states involving deranged carbohydrate metabolism.
