This patient had low urinary osmolality and a low sodium concentration, which is inconsistent with SIADH and hypovolemic hyponatremia. |
Treatment for mild and moderate SIADH can include fluid restriction, diuretics, and desmopressin. |
Treatment varies, depending on the severity of SIADH and other factors. |
Initial treatment for SIADH typically involves restriction of water intake and eradication of the underlying cause, if known. |
