Hydration status and the diuretic action of a small dose of alcohol

Hobson, Maughan · 2010 · Alcohol and Alcoholism 45(4):366-373

What this work gives Aellic

Twelve males drank 1 l of beer the morning after being dehydrated by 1.9 % of body mass, twice rehydrated beforehand and twice not. With 4 % ethanol against the same alcohol-free beer, urine output differed when euhydrated (1279 vs 1121 ml) but not when hypohydrated (261 vs 174 ml). The authors conclude that the diuretic action of alcohol is blunted when the body is already hypohydrated.

Correction of 12 September 2026

This entry first claimed vasopressin suppression as the paper's own finding and was attached to wine and spirits. Neither holds: the mechanism is not in the abstract, and the study measured BEER at 4 % ethanol, not wine or spirits. It now carries only the DIRECTION of the alcohol effect; the size of Aellic's deduction for wine and spirits (factor 0.0) is a construction decision with no measurement behind it.

The entry on the register was wrong. It was not replaced but kept, with what holds instead standing next to it.
