Nocturnal Polyuria: What is it and how to treat it?

What is Nocturnal Polyuria? 

Nocturnal polyuria is a condition that changes the day-to-night ratio of urine production. While daily output remains unchanged, more than 33% of urine output happens at night. During the day,  fluid is retained in the feet or legs, and when the body is reclining, that fluid finds its way to the kidneys, which produce urine. Individuals suffering from this condition may wake up several times during the night to urinate. Naturally, this affects sleep which impacts the quality of life and can make someone cranky and disoriented the next day. Since humans need 6-8 hours of uninterrupted sleep per night, serious sleep-related issues can develop if this continues.

Nocturnal Polyuria Causes

There are some  common causes of Nocturnal Polyuria, these include 

Nocturnal Urinary Frequency 

Urinating in small amounts or more frequently is known as Nocturnal urinary frequency. This can occur because the bladder cannot empty fully due to an obstruction or a prostate issue. It can also happen because the bladder needs to fill up completely before the sudden urge to urinate develops due to bladder spasms, infection, swelling and pain, or obstructive sleep apnea. 

Symptoms of Nocturnal Polyuria 

Symptoms of nocturnal polyuria are: 

  • Waking up more than once to urinate 
  • Increased volume of urine at night 
  • Feeling sleepy and tired during the day 

Treatment and Diagnosis 

For an efficient diagnosis, it is helpful to keep a daily log or a diary to record the following details: 

  • Note when the condition began 
  • Fluid intake during the day 
  • Frequency of urination 
  • Volume of urine 
  • Medications (if any) and if they cause you to urinate more 
  • Urinary tract infection 
  • Any other symptoms 
  • Caffeine and alcohol consumption 

 Some of the ways to treat nocturnal polyuria are as follows: 

  • Restricted fluid intake during the night: Drinking plenty of fluids during the day is fine but limit the intake at night. Avoid caffeine and alcohol as well. 
  • Consumption of diuretics: If you take diuretics, make sure to do so at least 6 hours before bedtime. This will cause you to urinate less during the night. 
  • Use compression stockings: For those who suffer from fluid retention in the legs and feet, compression stockings help prevent fluid buildup. Elevating the legs will help to redistribute fluids back into the bloodstream. 
  • Take afternoon naps: A nap is a good way to compensate for lost sleep and energy due to a disrupted night's sleep. 
  • Pelvic exercises: Take some time during the day to perform pelvic exercises to strengthen your bladder and the pelvis.  

Product Recommendations 

Waking up frequently during the night to urinate results in poor sleep quality. Constant moisture on the skin due to bedwetting can cause serious issues. Many incontinence products, such as underpads/chux, mattress covers, perineal skin care products, and overnight diapers and briefs, can help you manage this condition.

As with any medical issue, check with your healthcare provider to be sure that an underlying illness is not the cause of nocturnal polyuria. If lifestyle adjustments do not help with the condition, there are treatments and medications available that might provide relief. Over time, your symptoms should improve, the urinary frequency should reduce, and you should be able to attain a good night's sleep.
