Polyuria is inordinate or an abnormally large product or passage of urine (lesser than 2.5 L or 3 L over 24 hrs in grown-ups). Increased product and passage of urine may also be nominated diuresis. Polyuria frequently appears in confluence with polydipsia (increased thirst), though it's possible to have one without the other, and the ultimate may be a cause or an effect. Primary polydipsia may lead to polyuria. Polyuria is generally viewed as a symptom or sign of another complaint (not a complaint by itself), but it can be codified as a complaint, at least when its underpinning causes aren't clear.

The most common cause of polyuria in both grown-ups and children is unbridled diabetes mellitus, which causes bibulous diuresis, when glucose situations are so high that glucose is excreted in the urine. Water follows the glucose attention passively, leading to abnormally high urine affair. In the absence of diabetes mellitus, the most common causes are dropped stashing of aldosterone due to adrenal cortical excrescence, primary polydipsia (inordinate fluid drinking), central diabetes insipidus and nephrogenic diabetes insipidus. Polyuria may also be due to colorful chemical substances, similar as diuretics, caffeine, and ethanol. It may also do after supraventricular tachycardia’s, during an onset of atrial fibrillation, parturition, and the junking of an inhibition within the urinary tract. Diuresis is controlled by antidiuretics similar as vasopressin, angiotensin II and aldosterone. Cold diuresis is the circumstance of increased urine product on exposure to cold, which also incompletely explains absorption diuresis. High- altitude diuresis occurs at mound above bases (m) and is a desirable index of adaption to high mound. Perambulators who are conforming well to high mound witness this type of diuresis. Persons who produce lower urine indeed in the presence of acceptable fluid input are presumably not conforming well to altitude.

Polyuria in bibulous cases, increases inflow quantum in the distal nephron where inflow rates and haste are low. The significant pressure increase being in the distal nephron takes place particularly in the cortical- collecting tubes. One study from 2008 lays out a thesis that hyperglycemic and bibulous polyuria play places eventually in diabetic nephropathy.

Frequent urination is the need to urinate more frequently than usual. Diuretics are specifics that will increase urinary frequency. Nocturia is the need of frequent urination at night. The most common cause of urinary frequency for women and children is a urinary tract infection. The most common cause of urinary frequency in aged men is an enlarged prostate.

Frequent urination is explosively associated with frequent incidents of urinary urgency, which is the unforeseen need to urinate. It's frequently, though not inescapably, associated with urinary incontinence and polyuria (large total volume of urine). Still, in other cases, urinary frequency involves only normal volumes of urine overall.

Studies show that 5-15 of people who are 20-50 times old, 20-30 of people who are 50-70 times old, and 10-50 of people 70 times old, urinate at least twice a night. Nocturia becomes more common with age. Further than 50% of men and women over the age of 60 have been measured to have nocturia in numerous communities. Indeed more over the age of 80 are shown to witness symptoms of nocturia nocturnal. Nocturia symptoms also frequently worsen with age. Although nocturia rates are about the same for both genders, data shows that there's an advanced frequency in youngish women than youngish men and aged men than aged women.
