Nighttime Urination (Nocturia)

What Causes Nighttime Urination (Nocturia)?

Nighttime urination can have various causes, ranging in severity from 'troubling' to 'generally fatal'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose nighttime urination, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "nighttime urination" as a symptom.  Here are eight of many possibilities (more below):
  • Congestive Heart Failure
  • Sleep Apnea
  • Prostate Enlargement
  • Interstitial Cystitis
  • Diabetes II
  • Kidney Disease
  • Prostate Cancer
  • Hyperparathyroidism

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
prednisone use
fatigue after slight exertion
type 2 diabetes NIDD
severe vision disturbances
having an enlarged prostate
lighter/paler skin color
strong-smelling urine
yellow/yellowish fingernails
taking naps
shortness of breath when at rest
2hr postprandial glucose > 250mg%
mild abdominal discomfort
... and more than 80 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of nighttime urination:
Cause Probability Status
Prostate Enlargement 93% Confirm
Sleep Apnea 21% Unlikely
Congestive Heart Failure 20% Unlikely
Diabetes II 2% Ruled out
Prostate Cancer 2% Ruled out
Kidney Disease 1% Ruled out
Hyperparathyroidism 0% Ruled out
Interstitial Cystitis 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Urinary Symptoms section of the questionnaire, The Analyst™ will ask the following question about nighttime urination (nocturia):
Nighttime urination. On average, about how many times do you get up to urinate during your sleeping hours?
Possible responses:
→ Rarely / only if I drink too much / don't know
→ Once
→ Twice
→ Three times
→ Four or more times
Based on your response to this question, which may indicate little or no nighttime urination, nighttime urination or frequent nighttime urination, The Analyst™ will consider possibilities such as:
Kidney Disease

Changes in the frequency of urination, especially at night, may indicate kidney disease.

Congestive Heart Failure

Edema fluid that collects in tissues during the day due to heart failure can result in increased night time urination.

Fibroids

Fibroids can lead to increased urinary frequency and urgency.
