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):
  • Sleep Apnea
  • Mercury Toxicity
  • Kidney Disease
  • Interstitial Cystitis
  • Prostate Enlargement
  • Urinary Tract Infection
  • Diabetes II
  • 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:
very low HDL cholesterol level
being easily excitable
type 2 diabetes IDD
low cold water fish consumption
numb/burning/tingling extremities
weak urine stream
often/always feeling unusually cold
processed meat consumption
jaw lymph node problems
long-term low-carb dieting
African ethnicity
cold sores
... 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
Hyperparathyroidism 90% Confirm
Urinary Tract Infection 26% Unlikely
Prostate Enlargement 21% Unlikely
Diabetes II 0% Ruled out
Kidney Disease 0% Ruled out
Sleep Apnea 0% Ruled out
Interstitial Cystitis 0% Ruled out
Mercury Toxicity 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.
