Foamy Urine

What Causes Foamy Urine?

Foamy urine can have various causes, ranging in severity from 'needs attention' to 'very serious'.  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 foamy urine, 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 "foamy urine" as a symptom.  Here are four possibilities:
  • Chronic Fatigue-Fibromyalgia
  • Gallbladder Disease
  • Nephrotic Syndrome
  • Glomerulonephritis

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:
multiple swollen axillary nodes
tender muscles
morning stiffness that eases rapidly
six to ten tender points
dark urine color
meal-induced pain for 1-4 weeks
Caucasian ethnicity
temple-based headaches
vision disturbances
some loss of muscle tone
edema of the feet
dizziness when standing up
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of foamy urine:
Cause Probability Status
Chronic Fatigue-Fibromyalgia 91% Confirm
Glomerulonephritis 17% Unlikely
Nephrotic Syndrome 2% Ruled out
Gallbladder Disease 1% 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 foamy urine:
When you urinate, is foam produced in the toilet? This is known as 'foamy urine'.
Possible responses:
→ Don't know
→ No / extremely rarely
→ Occasionally foamy
→ Frequently foamy OR occasionally very foamy
→ Always very foamy
Based on your response to this question, which may indicate either not having foamy urine or having foamy urine, The Analyst™ will consider possibilities such as:
Gallbladder Disease

Most people get foamy urine now and again, typically because of muco-proteins in the fish, meat or chicken that they eat.  During digestion, the body doesn't break down these proteins completely, so they are expelled in the urine.  As muco-proteins shoot out of the body, they momentarily come in contact with air and then with water in the toilet bowl.  Foam appears because protein does not mix with air or water.

These bubbles occur most frequently in concentrated (dark) urine, like the urine that is passed right after waking up in the morning.  If the urine is extremely foamy and continues all the time, there may be a problem with bile salts or the gallbladder.

Nephrotic Syndrome

The first symptom of nephrotic syndrome is often foamy urine.
