• Often due to rapid urination / concentration.
• Sometimes linked to proteinuria (protein in urine), but since CUE is normal, serious
kidney disease is less likely.
• Could also happen due to dehydration or high urine flow from diuretics (furosemide).
Next Steps
Hydration: Drink enough water.
• Repeat urine protein (spot protein/
creatinine ratio) if foamy urine persists for weeks.
•
Kidney function test (serum creatinine, eGFR) for reassurance.
• If no protein, no blood in urine, and kidneys are normal → nothing to worry.
Health Tips
When to Worry
• Persistent heavy foamy urine (every time).
• Swelling of face/feet.
• Decreased urine output.
• Blood in urine.
