Foamy or bubbly urine can be a sign of proteinuria, which means protein is leaking into your urine. Healthy kidneys normally keep protein in your blood, but when the tiny filtering units (called glomeruli) are damaged, protein can slip through into your urine.
Foamy urine typically looks like layers of small to medium bubbles that stick around in the toilet bowl — even after flushing. A few quick-disappearing bubbles usually aren't a concern, but persistent foam is worth paying attention to. If protein levels in the urine are very high, it can sometimes point to nephrotic syndrome. Along with foamy urine, other symptoms may include:
- Swelling (edema) in your legs, feet, hands, or face
- Decreased appetite
- Stomach pain
- A general feeling of being unwell
If foamy urine is new or getting worse, it's important to contact your healthcare team as soon as possible. A simple urine test can check your protein levels and help guide next steps.
