Nephrotic Syndrome: Causes, Symptoms, Diagnosis, and Treatment

What is Nephrotic Syndrome?

Nephrotic syndrome is a kidney condition that causes your body to pass too much protein in your urine. This happens when the tiny filters in your kidneys, called glomeruli, are damaged. As a result, your body loses protein, which is important for health. In the United States, nephrotic syndrome can affect both children and adults. However, it is more common in children.

Because the kidneys are not working well, you may notice swelling in your legs, feet, or face. Early diagnosis and treatment are important. Therefore, understanding the signs of nephrotic syndrome can help you get care sooner.

Common Symptoms

Nephrotic syndrome often causes clear signs. But sometimes, symptoms can be mild at first. For example, you may notice swelling or changes in your urine. Here are the most common symptoms:

Swelling in the legs, ankles, feet, or face

Foamy or bubbly urine

Weight gain from fluid buildup

Feeling tired or weak

Loss of appetite

Urine that looks darker than usual

Because these symptoms can also happen with other health problems, it is important to talk to your doctor if you notice them.

Main Causes

There are several causes of nephrotic syndrome. Sometimes, the cause is a disease that starts in the kidneys. Other times, it is due to another health problem. The main causes include:

Minimal change disease (most common in children)

Focal segmental glomerulosclerosis (FSGS)

Membranous nephropathy

Diabetes (can damage kidney filters over time)

Lupus and other immune system diseases

Infections such as hepatitis or HIV

Certain medicines, like painkillers or antibiotics

Because the cause can affect treatment, your doctor will try to find out what is behind your nephrotic syndrome.

Diagnosis Methods

Doctors use several tests to diagnose nephrotic syndrome. First, they will ask about your symptoms and health history. Then, they may do the following tests:

Urine test: Checks for high protein levels

Blood test: Looks at protein, cholesterol, and kidney function

Kidney biopsy: A small piece of kidney is checked under a microscope

Imaging tests: Ultrasound or CT scan to see kidney size and shape

Because early diagnosis can help prevent problems, it is important to get tested if you have symptoms.

Treatment Options

Treating nephrotic syndrome depends on the cause. However, the main goals are to reduce symptoms and protect your kidneys. Common treatment options include:

Medicines to lower blood pressure

Water pills (diuretics) to reduce swelling

Medicines to lower cholesterol

Drugs to control the immune system, if needed

Diet changes, such as eating less salt

Because each person is different, your doctor will create a plan that fits your needs. In some cases, treating the underlying cause, like diabetes, can help manage nephrotic syndrome.

Lifestyle Tips and Prevention

While you cannot always prevent nephrotic syndrome, healthy habits can help protect your kidneys. For example, you can:

Eat a balanced diet with less salt

Stay active and maintain a healthy weight

Control blood sugar if you have diabetes

Avoid smoking and limit alcohol

Take medicines as prescribed

See your doctor for regular check-ups

Because early care can make a big difference, follow your doctor’s advice and watch for any new symptoms.

When to See a Doctor

If you notice swelling, foamy urine, or other signs of nephrotic syndrome, see a doctor soon. Early treatment can help prevent kidney damage. In addition, if you have diabetes or another kidney risk, regular check-ups are important. Do not wait if you feel unwell or see changes in your health.
