Nephrotic Syndrome In Adults
Nephrotic syndrome is a group of changes affecting the kidneys. These may involve:
- High amounts of protein in the urine
- High cholesterol in the blood
- Swelling in the body—mainly in the feet and legs
- Low levels of a certain protein in the blood

Tiny tubules inside the kidneys filter wastes from blood and make urine. If they aren’t working well, wastes and fluids build up in the body.
Causes are from kidney related health problems such as:
- Glomerulonephritis —inflammation of the kidney tissue from infection or other causes
- IgA nephropathy
- Minimal change disease
- Membranous nephropathy
Causes from other health problems that harm the kidneys such as:
- Diabetic nephropathy
- Buildup of irregular proteins— amyloidosis
- Systemic lupus erythematosus (SLE)
- Sickle cell disease
- Blood clots
- Some cancers
The doctor will ask about your symptoms and health history. Your answers and a physical exam may point to nephrotic syndrome. You may also have:
- Urine tests to look for blood, certain proteins, or other markers
- Blood tests to look for certain proteins or other markers, or count blood cells
- Chest x-ray
- Abdominal or renal ultrasound
- A kidney biopsy
You will be referred to a specialist for care.
Care depends on the cause. In some people, nephrotic syndrome goes away on its own.
If needed, care focuses on keeping the kidneys working and lowering the chances of further injury. It may involve:
- Changes in diet to watch protein, cholesterol, and salt intake
- Medicines to watch high blood pressure , ease fluid buildup, or lower the amount of protein in the urine
- Dialysis —a machine works for your kidneys by filtering your blood
