Polyuria is usually the result of drinking excessive amounts of fluids, particularly water and fluids that contain caffeine or alcohol, said Diabetes.co.uk.
The site continued: “It is also one of the major signs of diabetes mellitus.
“When the kidneys filter blood to make urine, they reabsorb all of the sugar, returning it to the bloodstream.
“In diabetes, the level of sugar in the blood is abnormally high.
“Not all of the sugar can be reabsorbed and some of this excess glucose from the blood ends up in the urine where it draws more water.
“This results in unusually large volumes of urine.”
