High vs low serum osmolality

WebA low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma. Syndrome of inappropriate ADH secretion occurs when excessive release of antidiuretic hormone results in inappropriately elevated urine osmolality (>100 mOsmol/L) relative to the blood plasma, leading to hyponatraemia. WebJun 28, 2024 · An uncommon exception occurs in psychotic patients with primary polydipsia who drink such large quantities of fluid that, despite appropriately suppressed ADH release, the excretory capacity of the kidney is overwhelmed. The diagnostic approach to the patient with hyponatremia will be reviewed here.
