An above normal increase in urination is termed polyuria. It is generally accepted that a urine output above 3L/day denotes polyuria. This increased output can be the result of an inability to concentrate urine or an increase is solute excretion.[1]

Associated Conditions

Polyuria is associated with the following conditions:[2]


  • A 24hr measurement of urine output and osmolality can be used to confirm the presence of polyuria. Urinalysis for glucose as well as measurement of solute excretion rate can help to differentiate the underlying cause of polyuria.
  • Imaging
  • Relevant imaging may be necessary to identify the underlying cause of polyuria, including MRI. [3]

Naturopathic Treatments

It is important to identify the underlying mechanism resulting in polyuria, and treatment protocols should be specific to each pathology.
