Urinary sodium and potassium excretion in fasting obese subjects

Abstract

Data are presented on the urinary excretion of sodium and potassium in 40 obese patients subjected to therapeutic starvation. Two patterns of sodium loss were observed: Either a uniform low-level loss or a fluctuating loss leading in some cases to marked sodium depletion. In three patients the response was a combination of these two patterns. © 1971, British Medical Journal Publishing Group. All rights reserved.
