What Is It ?
The Nephrotic Syndrome is not itself a disease, but a condition that is often caused by any of a group of diseases that damages the tiny blood-filtering units (glomeruli) in the kidneys, where urine is made.
The kidneys clean the blood by filtering out excess water and salt and waste products from food. Healthy kidneys keep protein in the blood; this protein dissolved in the blood maintains the thickness of the blood and its ability to draw water from the tissues. But kidneys with damaged filters may let protein leak into the urine (proteinuria).
Normally, a person loses less than 150 mg of protein in the urine in a 24-hour period. A person with nephrotic syndrome will lose around 25 times the normal amount. This is the primary indicator of NS.
