Polyuria is usually due to bladder motility, and physiological polyuria can be left untreated.
Normal adult urine output in 24h is about 1 to 2L, with an average of 1.5L, and more than 2500ml per day in 24 hours is clinically called polyuria.
The causes of polyuria need to be identified. 1. endocrine and metabolic diseases: uremia, diabetes mellitus, potassium deficiency, hypercalcemia. 2. polyuria caused by kidney disease is seen in the early stages of chronic renal failure, when it is characterized by increased nocturnal urine volume. The first of these is a new type of kidney disease.
Therefore, physiological polyuria requires lifestyle improvement, and pathological factors require treatment of the cause.
