Causes of proteinuria in nephrotic syndrome

Nephrotic syndrome proteinuria causes renal excretion function decline, glomerular filtration barrier damage, renal tubular structure abnormalities.

1. Renal excretion function decline in patients with renal excretion function

, the protein content in the daily diet is high, can not be completely absorbed by the body metabolism, protein may be excreted with the urine, the formation of proteinuria.

2. Glomerular filtration barrier damage

Nephrotic syndrome caused by patients with glomerular filtration rate decline, may lead to a large number of protein is filtered out, through the way of urine excretion, causing proteinuria.

3. Renal tubular structure abnormalities in patients with renal tubular structure abnormalities

, reabsorption function may appear abnormal, resulting in renal tubular reabsorption function decline, at this time will also appear proteinuria.
