Nephrotic Syndrome: Symptoms, Diagnosis & Treatment
A clear guide to nephrotic syndrome, covering the significant protein loss that causes swelling, and the treatment that helps most patients recover.
Treatment usually begins with
Nephrology Consultation
Urine Protein Testing
Medication Management
Dietary Guidance
Treatment typically combines medication to reduce protein loss and control swelling, alongside dietary changes to support recovery.
You may need this evaluated if...
A nephrology evaluation is recommended when these signs appear:
- Significant swelling in the legs, face or abdomen
- Foamy or frothy urine
- Unexplained weight gain from fluid retention
- Blood tests show low protein levels
Nephrotic syndrome responds well to treatment in most cases, especially in children, with many patients achieving full remission.
What is Nephrotic Syndrome?
Nephrotic syndrome occurs when damaged kidney filters allow large amounts of protein to leak into the urine, causing swelling and other characteristic symptoms.
Significant Protein Loss
Large amounts of protein leaking into the urine is the defining feature of this condition.
Common in Children and Adults
While frequently seen in children, nephrotic syndrome can affect people of any age.
Highly Treatable
Many patients, especially children, achieve full remission with the right treatment.
Needs Ongoing Monitoring
Regular follow-up tracks protein levels and watches for relapse.
Common Symptoms
- Significant swelling in the legs, face or abdomen
- Foamy or frothy urine
- Rapid weight gain from fluid retention
- Fatigue and loss of appetite
- Increased susceptibility to infection
What Increases Your Risk
A combination of medical, genetic and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Urine Protein Testing
Measures the amount of protein being lost, confirming the diagnosis.
Blood Tests
Checks protein and cholesterol levels, along with kidney function.
Kidney Biopsy (Selected Cases)
Identifies the specific underlying cause when needed to guide treatment.
Treatment Approaches
Medical Management
- Medication to reduce protein loss and control swelling
- Blood pressure and cholesterol management
- Dietary guidance around salt and protein intake
Advanced Care
Nephrotic syndrome is managed medically in almost all cases. Dialysis is considered only in rare instances of significant kidney function decline.
Treatment decisions are based on kidney function tests, the underlying cause and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly helps protect long-term kidney function.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- New or worsening swelling needing evaluation
- Foamy urine or unexplained weight gain
Seek Urgent Care
Reach out for emergency care immediately if you notice any of the following.
- Sudden, severe swelling with breathing difficulty
- Signs of serious infection
