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. WebAug 10, 2024 · If your serum osmolarity starts to climb too high, ADH will make you thirsty and signal your kidneys to retain water (by reducing urine output).
