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.
wa·ter di·u·re·sis(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.
occurs in hypothermia as a result of peripheral vasoconstriction, hyperglycemia and decreased renal tubular absorption.
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.
due to the diuretic effect of urea and electrolytes retained during the period of obstruction.
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.
