Nephrotic syndrome is a kidney disorder characterized by a combination of symptoms resulting from damage to the glomeruli (tiny filtering units), which causes excessive protein leakage into the urine, low protein levels in the blood, high cholesterol, and severe fluid retention (edema). It is not a specific disease but a set of symptoms indicating underlying kidney damage.
When your kidneys are filtering units, the glomeruli, which act as a fine mesh strainer, are tiny capillary clusters tucked deep within each kidney. Normally, that mesh holds back proteins while letting waste through. In nephrotic syndrome, the mesh tears. Protein, particularly albumin, pours into the urine in large quantities, typically more than 3.5 grams per day in adults. What follows is a cascade. Blood protein levels fall. Fluid shifts out of blood vessels into the surrounding tissue. Swelling begins. It is not a single disease. It is a pattern, a cluster of findings that points toward underlying kidney injury.

In children, symptoms can appear rapidly. In adults, they tend to build gradually, which is why nephrotic syndrome is often caught later than it should be.

Identifying the exact cause matters; it directly determines the treatment approach, and a kidney biopsy is often necessary to get that answer.
A 24-hour urine collection or a spot urine protein-to-creatinine ratio confirms heavy proteinuria. Blood tests show low albumin, often below 2.5 g/dL, and elevated cholesterol. Kidney function tests, a lipid profile, and an ultrasound of the kidneys are routinely done. In many adult cases, a kidney biopsy is necessary. A thin needle is passed under ultrasound guidance into the lower pole of the kidney, usually the left, to obtain a small tissue sample. This tells us exactly what type of glomerular injury is present and guides treatment decisions considerably. Consult experienced nephrotic syndrome doctors in Navi Mumbai at UMC Hospitals for further assistance.
Steroids remain the cornerstone for most cases, particularly in children. If the response is inadequate or relapses are frequent, immunosuppressants such as tacrolimus or mycophenolate may be added. Diuretics help manage swelling. ACE inhibitors reduce protein leakage and protect the kidney long-term. Diet matters more than most patients realise. Salt restriction is non-negotiable during active disease: no pickles, no papads, no packaged foods. Protein intake needs to be calibrated carefully; neither too much nor too little. A renal dietitian is genuinely helpful here. Infection risk is elevated because immunoglobulins are lost in the urine. Pneumococcal vaccination is recommended. Fever should never be waited out at home.
We are committed to providing the best nephrotic syndrome treatment in Navi Mumbai at UMC Hospitals. Our nephrology team in Navi Mumbai manages both paediatric and adult nephrotic syndrome with biopsy facilities, renal dietetic support, and structured follow-up protocols. If swelling, frothy urine, or unexplained fatigue is something you or your child has been experiencing, a conversation with a nephrologist sooner rather than later makes a real difference.
