: AVP excess associated with hyponatremia without edema or hypovolemia. The AVP excess is inappropriate in the face of hypoosmolality. Excess AVP secretion or action resuls in concentrated urine (Uosm > 300 mOsm/kg), low Sosm (Uosm > Sosm), low serum sodium. Urine sodium is usually above 20 mmol/L due to volume expansion inhibiting proximal tubule sodium reabsorption, increased GFR, suppression of the renin-angiotensin-aldosterone system, and increased production of atrial natriuretic peptide. This naturiesis tends to normalize extracellular fluid volume.

Ans is urinary sodium loss
