Hyponatremia due to excess ADH is best described as?

Explanation:
Excess ADH causes the kidneys to reabsorb more water, increasing total body water without a corresponding rise in sodium. This dilutes the serum sodium concentration, producing dilutional hyponatremia from water retention. It’s a euvolemic form seen in SIADH, not a lab artifact or dehydration-related hypernatremia, and not sodium overload. Management focuses on limiting fluid intake and addressing the underlying cause, with careful correction to avoid rapid shifts in sodium.
