Acute effects of ethanol intake on the serum concentrations of parathyroid hormone, calcium and phosphate.

Several previous observations from animal and in-vitro studies indicate that both the acute and chronic ingestion of ethanol could affect calcium regulation but little data is available concerning the effects of ethanol in man. Twelve healthy male subjects drank 0.8 g ethanol/kg body weight in the form of whisky so that the serum ethanol concentrations reached an average of 17.4 +/- 2.5 (SD) mmol/l. At this time there were no significant differences for the serum concentrations of parathyroid hormone, calcium or phosphate. Thus, it appears that there is little acute effect on calcium homeostasis in man of a moderate rise of serum ethanol levels.
