Diuresis Natriuresis
Definition Increased urine production Increased excretion of sodium in urine
Mechanism Increased fluid filtration and urine formation Increased renal sodium excretion
Primary Effect Increased urine output Increased sodium excretion
Water Balance May lead to fluid loss and dehydration May or may not affect overall fluid balance
Sodium Balance May or may not affect sodium balance Results in negative sodium balance
Hormonal Regulation Influenced by antidiuretic hormone (ADH), aldosterone, and atrial natriuretic peptide (ANP) Influenced by natriuretic peptides (ANP, BNP, CNP), aldosterone, and renin-angiotensin-aldosterone system (RAAS)
Conditions Can occur in various conditions, including diabetes insipidus, certain medications, and excessive fluid intake Can occur in conditions such as heart failure, kidney disease, and certain medications
Clinical Features Increased urine volume, increased thirst, dehydration symptoms (if excessive), electrolyte imbalances (if severe) Increased urine sodium concentration, decreased blood sodium levels, fluid retention in some cases
Diagnostic Tests Urine output measurement, urine specific gravity or osmolality Urine sodium measurement, blood electrolyte levels
Treatment Depends on the underlying cause, may involve fluid and electrolyte replacement or adjustment of medications Depends on the underlying cause, may involve sodium restriction, diuretic medications, or management of the associated condition
