Nephrotic Syndrome: What It Is
✓ Fact-checked against sourced references · Editorial standards
Nephrotic syndrome is a condition where the kidneys leak a large amount of protein into the urine, causing swelling and other changes.
The main signs
- Heavy protein in the urine (foamy urine)
- Swelling, especially around the eyes and legs
- Low blood protein and high cholesterol
Treatment
Treatment targets the underlying cause, often with medicines to reduce protein leak and control swelling and blood pressure.
