Study Notes
Diagnosing Polyuria: Guidelines and Tests
- Polyuria is defined as excessive urination (>3 liters/day for adults)
- Main causes include diabetes insipidus (DI), diabetes mellitus (DM), primary polydipsia (PP), and drug-induced polyuria
- Initial assessment includes a thorough history and physical examination
- Urine analysis can reveal specific gravity, glucose, blood, and protein levels
- The water deprivation test is used to distinguish between DI and PP
- Additional testing may include serum glucose, calcium, renal function tests, hormone levels, and imaging
- Treatment options include desmopressin for DI, insulin therapy and lifestyle modifications for DM, fluid restriction and addressing underlying psychiatric issues for PP, and adjusting or changing medication for drug-induced polyuria
- Furosemide, a loop diuretic, can cause polyuria, urinary frequency, and loss of electrolytes
- Spironolactone, an aldosterone antagonist, can cause polyuria, urinary frequency, and increased serum potassium
- Levothyroxine, a thyroid supplement, can cause polyuria and urinary frequency when oversupplemented and downregulation of aquaporin 1 and 2
- Dose adjustments for these medications should be made based on patient response and lab work
- Conduct the tests and treatments under medical supervision due to the risk of dehydration and other complications.
