HYPONATREMIA-SIADH

Nephrology

HYPONATREMIA-SIADH

1. Diagnose SIADH by comparing the urine and serum osmolalities.

2. Urine is inappro­priately concentrated (> 250 mOsm/L) in the setting of a low serum osmolality.

3. The mechanism for ADH release in hypothyroidism is decreased cardiac output, which stimulates the carotid baroreceptors.

4. Rule out hypothyroid­ism and glucocorticoid deficiency in all patients with normovolemic hyponatremia before making a diagnosis of SIADH.
