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.

Diagnose your symptoms now!
  • see your health summarized and in detail
  • learn what you should be doing right now
  • have a doctor review your case (optional)

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):
  • Sleep Apnea
  • Kidney Disease
  • Interstitial Cystitis
  • Mercury Toxicity
  • Prostate Cancer
  • Hyperparathyroidism
  • Fibroids
  • Diabetes II

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:
tossing and turning at night
sleeping more than necessary
excessive thirst
joint pain/swelling/stiffness
processed meat consumption
absent sexual desire
African ethnicity
gradual decline in speaking ability
very irregular menstrual cycles
high sugared soft drink consumption
back-of-neck lymph node problems
tender muscles
... and more than 110 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
Fibroids 91% Confirm
Hyperparathyroidism 21% Unlikely
Sleep Apnea 20% Unlikely
Kidney Disease 3% Ruled out
Diabetes II 1% Ruled out
Mercury Toxicity 0% Ruled out
Prostate Cancer 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.
