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.
