Nephrotic syndrome is a kidney-related condition characterised by excessive loss of protein through urine, leading to fluid imbalance and systemic health concerns. It can affect both children and adults and may present suddenly or develop gradually over time. As the condition can increase the risk of infections, blood clots, and long-term kidney complications, timely medical evaluation plays a critical role in effective management. With accurate diagnosis, available treatment options, and ongoing follow-up, many individuals with nephrotic syndrome are able to control symptoms and maintain kidney function over time.
What is Nephrotic Syndrome?
Nephrotic syndrome is a clinical condition that occurs when the kidney’s filtering units, known as glomeruli, become damaged and allow large amounts of protein to leak into the urine, a process known as proteinuria. Under normal circumstances, these filters prevent essential proteins from leaving the bloodstream. When this mechanism is disrupted, protein loss leads to widespread effects on fluid balance and overall health.
The condition is defined by a characteristic combination of findings, including heavy proteinuria, low levels of protein in the blood (hypoalbuminaemia), generalised swelling (oedema), and elevated blood cholesterol levels. Nephrotic syndrome is not a single disease but a manifestation of underlying kidney damage. Its course and response to treatment depend on the cause, age at onset, and overall kidney function.
Types of Nephrotic Syndrome
Nephrotic syndrome is broadly classified based on its underlying cause and the age at which it develops. Understanding the types helps guide evaluation, treatment planning, and long-term management. The types of nephrotic syndrome include:
Primary (Idiopathic) Nephrotic Syndrome
This form originates from diseases that directly affect the kidneys, particularly the glomeruli. It is more commonly seen in children but can also occur in adults. In many cases, the exact cause may not be immediately identifiable.
Secondary Nephrotic Syndrome
Secondary nephrotic syndrome develops as a result of other medical conditions that impact kidney function. These may include systemic diseases, infections, or long-term use of certain medications. Management focuses on treating both the underlying condition and the kidney involvement.
Congenital and Hereditary Nephrotic Syndrome
These rare forms are present at birth or develop early in infancy due to genetic abnormalities affecting kidney structure or function. They often require specialised care and long-term monitoring.
Causes of Nephrotic Syndrome
Nephrotic syndrome develops when the kidney’s filtering units, known as glomeruli, are damaged and lose their ability to prevent excessive protein leakage into the urine. This damage may originate within the kidneys themselves or occur as part of a broader systemic condition affecting overall health. The causes of nephrotic syndrome broadly include the following:
Primary (Kidney-Related) Causes
In primary nephrotic syndrome, the damage is limited to the kidneys. Disorders affecting the glomeruli alter their structure or function, leading to significant proteinuria. These causes are more commonly seen in children but can also affect adults.
Secondary (Systemic) Causes
Secondary nephrotic syndrome occurs when an underlying medical condition affects the kidneys over time. Chronic systemic illnesses can gradually impair kidney function and trigger protein loss through urine.
Infections, Immune Factors, and Medications
Certain infections, immune-mediated responses, and prolonged use of specific medications may damage the glomeruli or trigger inflammatory changes, resulting in nephrotic syndrome.
Idiopathic Causes
In some cases, no clear cause is identified despite detailed evaluation. Such cases are referred to as idiopathic nephrotic syndrome and require close monitoring and individualised treatment planning.
Symptoms of Nephrotic Syndrome
Nephrotic syndrome can present with a range of physical changes that reflect how the condition affects fluid balance and overall health. Symptoms may appear gradually or develop suddenly and can vary in severity depending on age, disease activity, and underlying cause.
Common symptoms include:
- Swelling (oedema): Swelling is the most recognisable feature and may affect the face (especially around the eyes), ankles, feet, legs, abdomen, or, in severe cases, the entire body.
- Foamy or frothy urine: Excess protein in urine often causes urine to appear bubbly or foamy, which may be one of the earliest visible signs.
- Sudden weight gain: Rapid weight gain may occur due to fluid retention rather than increased body fat.
- Fatigue and weakness: Low protein levels in the blood can lead to reduced energy levels and general tiredness.
- Reduced appetite: Abdominal swelling and systemic illness may contribute to poor appetite.
- Frequent infections: Loss of protective proteins weakens immune defence, increasing susceptibility to infections.
- Signs related to complications: Some individuals may experience leg pain, chest discomfort, or breathlessness due to blood clots, which require urgent medical attention.
Symptoms may vary between children and adults. Children often present with facial puffiness, especially in the morning, while adults may develop swelling in the lower limbs along with blood pressure or cholesterol abnormalities.
Complications Associated with Nephrotic Syndrome
Nephrotic syndrome can lead to several complications if protein loss and fluid imbalance are not adequately controlled. These complications may affect multiple organ systems and increase long-term health risks, such as.
- Increased risk of infections: Loss of protective proteins weakens immune defence, making individuals more susceptible to bacterial and other infections.
- Blood clots (thromboembolism): Changes in blood clotting factors increase the risk of clots forming in veins or arteries, which may lead to serious complications.
- High cholesterol and cardiovascular risk: Nephrotic syndrome is often associated with elevated cholesterol levels, increasing the risk of blood vessels and heart diseases.
- Reduced kidney function: Ongoing damage to the kidneys can gradually impair their ability to filter blood effectively, potentially progressing to chronic kidney disease.
- Nutritional deficiencies: Persistent protein loss may contribute to muscle weakness, fatigue, and poor nutritional status over time.
Early diagnosis, appropriate treatment, and regular follow-up play a key role in reducing the risk of these complications and supporting long-term kidney health.
How is Nephrotic Syndrome Diagnosed?
Diagnosing nephrotic syndrome requires a structured clinical evaluation to confirm excessive protein loss, assess kidney function, and identify the underlying cause. The diagnostic approach typically includes:
- Clinical evaluation and medical history: Assessment of symptoms such as swelling, changes in urine appearance, blood pressure levels, and any existing medical conditions.
- Urine tests: Tests to measure protein levels in urine, which help confirm abnormal protein loss and monitor disease severity.
- Blood tests: Evaluation of kidney function, protein levels, cholesterol, and other parameters to understand the systemic impact of the condition.
- Imaging studies: Ultrasound or other imaging techniques may be used to assess kidney size, structure, and rule out structural abnormalities.
- Kidney biopsy (when indicated): In selected cases, a kidney biopsy is performed to determine the exact kidney disorder causing nephrotic syndrome and guide targeted treatment.
Treatment Options for Nephrotic Syndrome
Treatment for nephrotic syndrome focuses on reducing protein loss, controlling symptoms, preventing complications, and addressing the underlying cause. The treatment plan is tailored based on age, disease severity, response to therapy, and associated medical conditions. Treatment options include:
- Medications to reduce inflammation and protein loss: Certain medications help control immune-related kidney damage and reduce the leakage of protein into urine.
- Management of swelling and fluid balance: Medicines may be prescribed to reduce fluid retention and relieve swelling, along with guidance on fluid intake when required.
- Blood pressure and cholesterol control: Treatment may include medications to manage high blood pressure and elevated cholesterol levels, both of which are common in nephrotic syndrome.
- Dietary and supportive care: Nutritional guidance focuses on adequate protein intake, salt restriction, and overall kidney-friendly dietary practices.
- Long-term monitoring and follow-up: Regular follow-up with a nephrologist is essential to monitor kidney function, treatment response, and prevent relapses or complications.
When to See a Doctor?
Nephrotic syndrome requires timely medical attention, especially when symptoms worsen or new concerns develop. Early consultation with a specialist can help prevent complications and support better long-term kidney outcomes. Medical evaluation is recommended in the following situations:
- Persistent or increasing swelling of the face, legs, abdomen, or around the eyes
- Sudden or unexplained weight gain due to fluid retention
- Foamy or frothy urine that does not improve
- Reduced urine output or noticeable changes in urine frequency
- Recurrent infections or delayed recovery from common illnesses
- Symptoms of blood clots, such as unexplained leg pain, swelling, or shortness of breath
- Poor response to ongoing treatment or frequent relapses, especially in children
Prompt assessment by a nephrologist helps ensure appropriate investigations, treatment adjustments, and close monitoring when needed.

Frequently Asked Questions
What is the difference between nephrotic syndrome and glomerulonephritis?
Nephrotic syndrome refers to a group of symptoms caused by significant protein loss in urine, while glomerulonephritis is an inflammatory condition affecting the kidney’s filtering units. Glomerulonephritis can sometimes lead to nephrotic syndrome, but the two are not the same.
What is the difference between nephrotic syndrome and nephritic syndrome?
Nephrotic syndrome is primarily characterised by heavy protein loss, swelling, and low blood protein levels. Nephritic syndrome, on the other hand, is marked by blood in urine, high blood pressure, and reduced kidney function due to inflammation.
Can nephrotic syndrome cause anaemia?
Yes. Chronic protein loss and kidney involvement can contribute to anaemia over time, especially in long-standing or poorly controlled cases.
Can nephrotic syndrome go away on its own?
In some cases, especially in children, nephrotic syndrome may respond well to treatment and go into remission. However, medical evaluation and follow-up are essential, as untreated disease can lead to complications.
Is nephrotic syndrome hereditary?
Most cases are not inherited. However, certain rare forms of nephrotic syndrome, especially those that appear in infancy or early childhood, may have a genetic basis.
Does nephrotic syndrome always lead to kidney failure?
No. Many patients maintain stable kidney function with appropriate treatment and monitoring. The risk of kidney failure depends on the underlying cause, disease severity, and response to therapy.
Can nephrotic syndrome cause high blood pressure?
Yes. Fluid retention and kidney involvement can lead to elevated blood pressure, which requires careful monitoring and management.
Does nephrotic syndrome affect both kidneys?
Nephrotic syndrome typically involves both kidneys, as it affects the filtering units responsible for blood purification.
Can adults develop nephrotic syndrome?
Yes. Although more common in children, nephrotic syndrome can occur in adults and is often associated with underlying medical conditions.
Is nephrotic syndrome curable?
Nephrotic syndrome is usually manageable rather than permanently curable. Many patients achieve remission with treatment, but some may experience relapses that require ongoing care.
