Answer

Answer

SIADH may result from concomitant pulmonary infection or from persistent nausea from medications or gastrointestinal disease. Hyporeninemic hypoaldosteronism, a cause of type IV renal tubular acidosis manifesting as hyperkalemia with normal anion gap metabolic acidosis, is much more common when renal insufficiency is present.
