Alcohol decreases insulin sensitivity in healthy subjects.
To study the effect of alcohol on glucose and insulin metabolism, a simultaneous infusion of glucose and insulin was given for 150 min to healthy volunteers, once during alcohol and once during calorie-free gingerale (control) ingestion. During alcohol intake, the average steady-state (between 100 and 150 min) glucose of 5.44 +/- 0.39 mmol/l. and the average steady-state insulin of 6.3 +/- 1.1 ng/ml were significantly higher than those (4.0 +/- 0.39 mmol/l. of glucose and 4.4 +/- 0.6 ng/ml of insulin) observed during the control state. Despite the higher steady-state insulin concentrations, the glucose metabolism was significantly less during alcohol ingestion. These findings suggest alcohol-induced impairment in glucose metabolism is caused by a decreased tissue sensitivity to insulin.
