Nephrotic syndrome is a condition marked by very high levels of protein in the urine; low levels of protein in the blood; swelling, especially around the eyes, feet, and hands; and high cholesterol. Nephrotic syndrome results from damage to the kidneys' glomeruli (the singular form is glomerulus). Glomeruli are tiny blood vessels that filter waste and excess water from the blood and send them to the bladder as urine.
Nephrotic syndrome can occur with many diseases, including the kidney diseases caused by diabetes mellitus, but some causes are unknown. Prevention of nephrotic syndrome relies on controlling these diseases.
Glomerulosclerosis refers to scarring or hardening of the glomeruli -- blood vessels located in the kidneys. The glomeruli filter the blood as it passes through the kidneys. They remove waste fluids that then leave the body as urine.
Damaged glomeruli can't perform their job adequately. As a result, large amounts of protein from the blood leak into the urine rather than remaining in the bloodstream. This leads to a condition called proteinuria.
Glomerulosclerosis can affect children and adults...
Nephrotic syndrome may go away once the underlying cause, if known, has been treated. However, most of the time a kidney disease is the underlying cause, and these diseases cannot be cured. In these cases, the kidneys may gradually lose their ability to filter wastes and excess water from the blood. If kidney failure occurs, the patient will need dialysis or a kidney transplant.

Additional Information on Nephrotic Syndrome
The National Kidney and Urologic Diseases Information Clearinghouse collects resource information on kidney and urologic diseases for the Combined Health Information Database (CHID). CHID is a database produced by health-related agencies of the Federal Government. This database provides titles, abstracts, and availability information for health information and health education resources.
To provide you with the most up-to-date resources, information specialists at the clearinghouse created an automatic search of CHID. Or, if you wish to perform your own search of the database, you may access the CHID Online web site (http://chid.nih.gov) and search CHID yourself.
