When a child is diagnosed with nephrotic syndrome, it’s a kind of nightmare for parents. They feel scared and worried, and many parents imagine it as kidney failure. In fact, in most cases, nephrotic syndrome responds well to treatment.
What Is Nephrotic Syndrome?
In simple language, kidneys act as a pair of smart filters that purify blood, remove waste, and keep important things inside—especially protein. Protein helps maintain balance in the body, prevents swelling, fights infections, and builds healthy tissues.
In nephrotic syndrome, these filters become leaky. Instead of holding protein in the blood, they allow it to escape into the urine. The body loses too much protein, and as a result, the following are seen:
- Swelling occurs
- Urine becomes foamy
- Blood protein levels drop
- Cholesterol increases
When to Suspect Nephrotic Syndrome
- Swelling around the eyes (especially in the morning)
- Swelling of legs, feet, abdomen, and genitals
- Frothy urine
- Weight gain from fluid buildup
- Less urine than usual
Why Does It Happen?
- In most children, the exact cause is unknown. It is not due to diet, injuries, or infections the child had in the past. In the majority of cases, it is not hereditary.
- The immune system sometimes becomes overactive and affects the kidney filters, making them swollen and leaky.
- It is not contagious.
- Most children have a type called Minimal Change Disease, which responds very well to treatment.
How Is It Diagnosed?
Urine Test
- Shows high levels of protein.
- Dipstick tests may be advised for home monitoring.
Blood Test
- Low albumin (blood protein)
- High cholesterol
- Usually normal kidney function
Most children do not need a kidney biopsy.
Treatment Plan
1. Steroid Medicines (Prednisolone)
- Main treatment
- Helps stop protein leakage
- Usually works within 1–3 weeks
- Dose is high at first, then slowly reduced
Are Steroids Safe?
When used correctly, steroids are safe and very effective. Some temporary side effects may appear, such as:
- Increased appetite
- Mood swings
- Roundness of the face (“moon face”)
- Stomach upset
- Mild weight gain
These effects are reversible and improve once the dose is reduced.
2. Salt-Restricted Diet
- Avoid foods high in salt: chips, pickles, instant noodles, processed foods.
- Helps reduce swelling.
3. Diuretics (Water Pills)
- Sometimes given if swelling is severe.
4. Albumin Infusion
- Given in hospital if swelling is extreme or urine output is very low.
5. Preventing Infections
- Children with nephrotic syndrome can get infections easily.
- Yearly flu vaccine and pneumococcal vaccine are recommended.
Let Us Look into the Relapses
A relapse of nephrotic syndrome means protein has returned to the urine after a period of remission. Parents often worry that relapse means the kidneys are getting worse, but that is not true. Relapses are common in childhood nephrotic syndrome, especially when the child gets a cold or viral infection.
Signs of Relapse
- Swelling reappears
- Urine dipstick shows ++++ or +++ protein
- Morning puffiness
Most relapses respond quickly to another short course of steroids.
Home Care Tips
- Check urine protein daily during relapse and weekly during remission.
- Give medicines exactly as prescribed; do not stop suddenly.
- Encourage a healthy diet and plenty of water unless the doctor advises otherwise.
- Protect the child from infections (handwashing, avoiding sick contacts, vaccination).
- Allow normal play and school activities unless the child is very swollen.
When to Seek Medical Help Urgently
In nephrotic syndrome, the kidney’s smart filters become leaky, allowing precious protein to escape into the urine.
Seek immediate medical care if any of the following occur:
- Fever or infection
- Difficulty breathing
- Severe abdominal pain
- Very little urine
- Blood in urine
- Swelling not improving
- No response to steroids in the first episode
If any of these occur, visit a hospital immediately.
What Can Be Expected in the Long Term?
- 80–90% of children have the minimal change type of nephrotic syndrome
- This type responds extremely well to treatment
- Many children stop having relapses by age 10–12
- Long-term kidney damage is rare
- Growth and development remain normal
- Children can play sports, attend school, and live full lives
Only a small portion of children develop frequent relapses or steroid dependence. Even in those cases, safe medicines are available that help control the disease.
A Final Message to Parents
Nephrotic syndrome can feel overwhelming at first. Seeing a child swollen and hospitalized can be traumatizing. But what should be remembered is:
- This condition is treatable
- Most children recover beautifully
- Relapses are expected and manageable
- You are not alone—your doctor will guide you at every step
With proper care, medicines, and monitoring, children with nephrotic syndrome can have a healthy, active, and normal childhood without fear.
