How does urea help hyponatremia?
As urea is excreted, the decrease in plasma urea causes a fall in plasma osmolality, but the loss of water increases the plasma sodium concentration by 5 mequiv./l, which prevents water from reentering the brain.
How much does urea increase sodium?
Urea therapy was associated in the entire study group with a plasma sodium increase from 124 mEq/L to 130.5 mEq/L(P<0.001). Among the patients who received only urea, the plasma sodium increased from 125 mEq/L to 132 mEq/L (P<0.001). No ill effects from the treatment were reported.
What does oral urea do?
Oral urea functions as an osmotic diuretic (an “aquaretic”). Ingested urea will be completely excreted by the kidneys. It is excreted along with water, so the ultimate effect is removal of water. The amount of water removed depends on the urine tonicity.
