Polyuria refers to the excessive urination urine (at least 2. 5 litters a day for adult), resulting in profuse urination and urinary frequency.

Excess urine can be divided into different subcategories. The first relates to an increase in the total volume of urine known as polyuria. Secondly, there may be a dysfunction in which urination problems with storing and emptying urine. Finally, urinary incontinence may occur in which there is an involuntary loss of urine.


The amount of urine excreted depends on the body's electrolyte balance. The excess fluid or the need to remove an excess of dissolved substances can lead to an increase in the amount of urine produced by the kidneys. It also depends on the filtering capacity of the kidney: when the renal tubules may be unable to absorb the filtered blood which determines an increase in the amount of urine produced.
