Alcohol impairs insulin sensitivity in normal subjects.


The effects of alcohol on insulin action are not yet clearly established. To assess the effects of intravenously administered ethanol on insulin mediated glucose disposal, euglycaemic clamps at 3 different plasma insulin levels and insulin receptor binding studies on circulating monocytes after alcohol infusion were performed. Ethanol infusion leads to a significant reduction of insulin mediated glucose disposal (7.08 +/- 0.4 vs 8.6 +/- 0.6 mg/Kg/min; 9.8 +/- 0.7 vs 13.4 +/- 0.7; 14.7 +/- 0.7 vs 18.1 +/- 0.7 at 33, 73 and 760 mU/m2/min insulin infusion rate respectively). Monocyte insulin-receptor binding was decreased in all the subjects from 30 to 60% after ethanol infusion. These results demonstrate that alcohol can adversely influence the insulin mediated glucose disposal.
