Understanding Nephrotic Syndrome in Children: Symptoms, Causes, Diagnosis, and Treatment

Introduction

Nephrotic syndrome in children is a kidney condition that causes the body to lose too much protein in the urine. Because this can lead to swelling and other health problems, it is important for parents and caregivers to know the signs. Early detection and treatment can help children live healthy lives. According to the National Kidney Foundation, nephrotic syndrome is more common in children than adults. Therefore, understanding this condition can help families take the right steps.

Symptoms of Nephrotic Syndrome

Children with nephrotic syndrome often show clear signs. However, some symptoms may be mild at first. Watch for these common symptoms:

Swelling around the eyes, ankles, or feet (edema)

Foamy or bubbly urine

Weight gain from fluid buildup

Loss of appetite

Tiredness or feeling weak

Less urine than usual

Sometimes, children may also have high blood pressure. If you notice these symptoms, it is important to talk to a doctor right away.

Common Causes and Risk Factors

Nephrotic syndrome in children can have several causes. Most often, it is due to a problem with the tiny filters in the kidneys, called glomeruli. The most common type in children is minimal change disease. This means the kidney looks normal under a regular microscope, but it does not work properly. Other causes include:

Infections, such as hepatitis or HIV

Genetic conditions

Autoimmune diseases, like lupus

Use of certain medicines

Although any child can develop nephrotic syndrome, it is more common in boys and children between ages 2 and 6. Family history may also increase risk.

How Nephrotic Syndrome Is Diagnosed

Doctors use several tests to diagnose nephrotic syndrome in children. First, they will ask about symptoms and do a physical exam. Next, they may order these tests:

Urine test to check for high protein levels

Blood test to measure protein and kidney function

Blood pressure check

Sometimes, a kidney biopsy (removing a small piece of kidney tissue for testing)

Early diagnosis helps start treatment quickly and prevents complications.

Treatment Options and Management

Treatment for nephrotic syndrome in children aims to reduce symptoms and prevent future problems. Most children respond well to medicines. Common treatments include:

Steroid medicines to reduce swelling and protein loss

Water pills (diuretics) to help remove extra fluid

Medicines to control blood pressure

Special diets with less salt

Doctors may also treat infections if needed. In some cases, children need other medicines if steroids do not work. Regular check-ups are important to watch for side effects and track progress.

Lifestyle Tips and Home Care Guidance

Along with medical treatment, home care plays a big role. Here are some helpful tips for parents and caregivers:

Encourage a low-salt diet to reduce swelling

Help your child take medicines as prescribed

Monitor your child’s weight and swelling daily

Keep track of urine changes

Make sure your child gets enough rest

Teach your child to wash hands often to prevent infections

With good care at home, many children manage their symptoms well.

Prevention and When to Seek Medical Help

While it is not always possible to prevent nephrotic syndrome in children, early action can help. For example, treating infections quickly and avoiding certain medicines may lower risk. Always talk to your doctor before giving your child new medicines. Seek medical help if your child has:

Sudden swelling or weight gain

Very little or no urine

High fever or signs of infection

Shortness of breath

Prompt care can prevent serious problems and help your child recover faster.
