water diuresis

wa·ter di·u·re·sis

excretion of urine after drinking water; results from reduced secretion of the antidiuretic hormone of the neurohypophysis in response to the lowered osmotic pressure of the blood.

(wawtĕr dīyūr-ēsis)
Excretion of urine after drinking water; results from reduced secretion of antidiuretic hormone of neurohypophysis in response to the lowered osmotic blood pressure.


increased excretion of the urine.

cold diuresis
occurs in hypothermia as a result of peripheral vasoconstriction, hyperglycemia and decreased renal tubular absorption.
osmotic diuresis
due to increased concentration of solutes which are not reabsorbed in the proximal tubules and which, by osmotic pressure, cause water to be retained. See also osmotic diuretic.
postobstruction diuresis
due to the diuretic effect of urea and electrolytes retained during the period of obstruction.
water diuresis
ingestion and excretion of an excess of water, without a corresponding amount of sodium; involves expansion of plasma volume, increased left atrial pressure and inhibition of ADH. See also obligatory water diuresis.

However, it is difficult to determine the influence of cortisone on UFC excretion in quantitative terms because interference by cortisone depends not only on its cross-reactivity with the binding protein but also on the diuresis-induced increase in cortisone excretion, which changes markedly with time of day: water diuresis in the morning (zenith of adrenal activity) presumably has a more pronounced effect on cortisone excretion than water diuresis in the evening (nadir of adrenal activity).
Urinary free cortisol is not affected by short-term water diuresis [Letter].
As expected, the urine volume was significantly greater during water diuresis (P <0.
