Nephrotic syndrome is a group of symptoms that include protein in the urine, low blood protein levels, high cholesterol levels, high triglyceride levels, and swelling.
Nephrotic syndrome is caused by different disorders that damage the kidneys. This damage leads to the release of too much protein in the urine.
The most common cause in children is minimal change disease. Membranous glomerulonephritis is the most common cause in adults.
This condition can also occur from:
Diseases such as diabetes, systemic lupus erythematosus, multiple myeloma, and amyloidosis
Infections (such as strep throat, hepatitis, or mononucleosis)
Use of certain drugs
Treatment of nephrotic syndrome depends on the cause of the disease and may include:

Treatment if the condition gets worse
Sometimes treatment for nephrotic syndrome is unsuccessful. If this occurs, you may develop chronic kidney disease. Your doctor may recommend that you beginhemodialysis, peritoneal dialysis, or consider a kidney transplant. For more information, see the topic Chronic Kidney Disease.
Clinical trials are ongoing to test more effective medicines for the treatment of steroid-resistant (relapsing) nephrotic syndrome. If treatment has not successfully controlled your nephrotic syndrome, ask your doctor about clinical trials. To take part in a clinical trial, you may need to travel to a large treatment center.
