| 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 |
