Polyuria is a condition where the body urinates more than usual and passes excessive or abnormally large amounts of urine each time you urinate.
Polyuria is defined as the frequent passage of large volumes of urine – more than 3 litres a day compared to the normal daily urine output in adults of about 1 to 2 litres.
It is one of the main symptoms of diabetes (both type 1 and type 2 diabetes) and can lead to severe dehydration, which if left untreated can affect kidney function.
Causes of polyuria
Polyuria is usually the result of drinking excessive amounts of fluids (polydipsia), particularly water and fluids that contain caffeine or alcohol.
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.
Other causes of polyuria include:
Diabetes inspidus – a condition unrelated to diabetes mellitus that affects the kidneys and the hormones that interact with them, resulting in large quantities of urine being produced
Kidney disease
Liver failure
Medications that include diuretics (substances that increase the excretion of water from the body/urine)
Chronic diarrhoea
Cushing’s syndrome
Psychogenic polydipsia – excessive water drinking most often seen in anxious, middle-aged women and in patients with psychiatric illnesses
Hypercalcemia – elevated levels of calcium in the blood
Pregnancy
Polyuria as a symptom of diabetes
As well as being one of the symptoms of undiagnosed diabetes, polyuria can also occur in people with diagnosed diabetes if blood glucose levels have risen too high.
If blood glucose levels become too high, the body will try to remedy the situation by removing glucose from the blood through the kidneys. When this happens, the kidneys will also filter out more water and you will need to urinate more than usual as a result.

Recent research has shown that nocturnal polyuria (NP) is a heterogeneous condition that may be driven by excess nocturnal free water and/or sodium clearance. Consistently, behavioral and pharmacologic interventions targeting both nocturnal free water and sodium production have garnered considerable traction in the management of nocturia owing to NP. Relatively less attention has been afforded to urea—the most abundant urinary solute—despite the fact that urinary urea excretion is known to be highly interrelated with dietary protein intake [1]. Mechanistically, the body maintains a low concentration level of urea in both plasma and extracellular fluid, which lends to a daily urea excretion approximately two times greater the total body urea pool (and thus proportionally far greater than sodium, wherein daily excretion reflects approximately one-fifteenth of the total body sodium pool) [1]. Accordingly, it stands to reason that excretion of a large quantity of urea, as would be expected in patients following significant dietary protein intake, may reflect an additional important mediator in the pathogenesis of NP. This study aims to explore the association between NP and estimated dietary protein intake.

Dr. Blaivas explains that getting up in the middle of the night to urinate is called nocturia. Reasons for nocturia include the bladder not holding enough to allow the patient to sleep through the night, and the patient’s kidney potentially making more urine than the bladder can hold. Nocturnal polyuria is when too much urine is produced overnight, therefore causing the patient to get up in the middle of the night to urinate.
Jerry Blaivas, MD: Getting up in the middle of the night to urinate is called nocturia. Nocturia is very very common, in fact most people get up once or twice at night to urinate starting in the teenage years even.
If you think about it, there is only two possible reasons why someone would get up in the middle of the night to urinate. One is that their bladder does not comfortably hold enough to allow them to sleep through the night, and, two, you make more urine, that it is to say your kidney is making more urine then your bladder cannot comfortably hold overnight.
The second condition, we called nocturnal polyuria. The nocturnal means nighttime and poly means too much and uria means urine. So nocturnal polyuria means that you make too much urine overnight and that is probably the commonest cause of nocturia.
The most common cause of that even is just drinking too much before you go to sleep. So if you have a couple of beers or you have wine before dinner and then you take a glass of water with some pills, all of that fluid that you ingest will then overnight be converted by the kidneys to urine and then if you make more urine overnight than your bladder can hold, then of course you have to get up to urinate.
So nocturnal polyuria is the commonest cause and the other cause, the bladder not holding enough urine, has many many many causes. Probably the most common one is, temporary problem is, urinary tract infection. It can be caused by blockages by the prostate. It can be caused by bladder cancer, by all kinds of other irritable kind of conditions so thinking back then we have these two different causes, making too much urine at night or the bladder not holding enough at night. So, then what to do about it.
Well the first thing you need to do about it is to diagnose it. How do we diagnose it? Very – very simply! We have you keep a bladder diary, that is to say you record the time and amount of urine, time and amount of each urination that you make in a 24-hour period, then we simply see how much you urinate at night, how much you urinate for the 24-hours and through some mathematical formula, we can figure out if you are making too much urine at night.
Generally, people make less than a third of their urine during sleep hours. If you make more than that then you have this nocturnal polyuria and we look for the causes of that. I briefly alluded to what they were in the beginning but now to get more complete, the most common cause is simply drinking too much.
Probably the second most common cause is people that take medications at night that can have a diuretic like effect. Another cause is anything that causes your legs to swell up, so people with varicose veins or from prior surgery, if your leg swell up during the day that the swelling is actually fluid and when you lie down at night, your body resorbs that fluid, that fluid gets into your system and the kidneys make more urine.
Another common cause is something called sleep apnea, people who snore, best diagnosed by going to a sleep lab and if you have sleep apnea, then that is what causes the problem and the treatment of the sleep apnea is the problem.
The bladders that do not hold enough urine, again we first determine that by the bladder diary and then we look for the common causes, common causes of urinary tract infection, prostatic obstruction, dropped bladder in women, overactive bladder, sometimes bladder cancer, bladder stones, no matter what they cause though, once the diagnosis is clearly understood then treatment of the underlying condition that is causing the nocturia is very often effective, it is usually effective.
However, just having nocturia, just getting up at night to urinate by itself does not demand any treatment.
So if you get up once or twice at night or three times and you are not bothered by it, there is no need for any treatment at all. If there is a need for treatment, if you are bothered by it, rest assured there just about always an effective treatment.

Nocturia is defined by the International Continence Society (ICS) as “the complaint that the individual has to wake at night one or more times for voiding (i.e. to urinate).” The term is derived from Latin nox, night, and Greek [τα] ούρα, urine. Causes are varied and can be difficult to discern.[Although not every patient needs treatment, most people seek treatment for severe nocturia, waking up to void more than 2–3 times per night.

Nocturia is a common urological problem with a high prevalence (up to 60%) especially in elderly patients (1). The underlying causes for nocturia are various, such as conditions causing sleeping disorders, bladder storage problems, and nocturnal polyuria. Patients with nocturnal polyuria have an increased production of urine during nighttime (i.e. one third or more of the total volume of urine produced in 24-hours) (2). Nocturnal polyuria may be present in patients with obstructive sleep apnea (OSA) and treatment with continuous positive airway pressure (CPAP) reduces nighttime frequency and nocturnal voided volume in patients with OSA (3).
In this study, we examined the amount of patients with nocturnal polyuria that suffer from OSA.
Subsequently, we offered patients with confirmed OSA treatment with CPAP, and analyzed the effect on episodes of nocturia and the nocturnal polyuria index (NPi= voided volume during night time/voided volume in 24 hours*100).

Frequent urination and excessive drinking are two non-specific symptoms that may be associated with many different diseases in pets. Called ‘polyuria and polydipsia’ (PUPD), they frequently appear in combination. In general, increased production of urine is the primary cause, and pets drink more to make up for the water being excreted.

Are you confused about what polyuria, polydipsia and polyphagia mean, and what you need to know about them in nursing school?
In this video, I’ll break down exactly what polyuria, polydipsia and polyphagia are, and how they relate to the med-surg disorders you’re learning about during nursing school.
Here’s a breakdown of what we’ll talk about:
Polyuria means excessive urination, polydipsia means excessive thirst, and polyphagia means excessive hunger.
These 3 symptoms are sometimes referred to as the “3 P’s” and probably the most common disorder you’ll hear them associated with is diabetes.
During diabetes, the body can’t use glucose for energy, so it uses fat instead. And this leads to a lot of extra glucose in the blood (hyperglycemia).
So polyuria, polydipsia, and polyphagia occur as compensatory mechanisms to try to reduce the blood sugar level.
In this video, I’ll go deeper into this concept of how the body uses polyuria, polydipsia, and polyphagia to reduce blood sugar levels.
I hope you enjoy it! 🙂
