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:
|Chronic Fatigue-Fibromyalgia||5%||Ruled out|
|Nephrotic Syndrome||3%||Ruled out|
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
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.
IgAN is suspected when protein and blood (visible or not) are found in the urine, and is ultimately diagnosed by biopsy. Acute IgAN is often accompanied by heavy proteinuria. Protein in the urine is not visible as such, but unusually foamy urine is often a clue to its presence.
The first symptom of nephrotic syndrome is often foamy urine.
