osmotic diuresis

Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

os·mot·ic di·u·re·sis

diuresis due to a high concentration of osmotically active substances in the renal tubules (for example, urea, sodium sulfate), which limit the reabsorption of water.

osmotic diuresis

diuresis resulting from the presence of certain nonabsorbable substances in tubules of the kidney, such as mannitol, urea, or glucose.


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.

The decrease in the rate of NMC in diabetic patients could be due to a decrease in ATPase activity, poor stimulation (due to neuropathy), osmotic diuresis (with its loss of water and electrolytes), and altered carbohydrate metabolism.
