What Symptoms May Appear If Patient Has Proteinuria

In fact, proteinuria is a dangerous symptom for patient with kidney disease, which can cause other problems to patient’s body health.

Why patient with kidney disease has proteinuria?

There is glomerular filtration membrane in nephron, which can keep protein in blood, and filter out metabolic wastes through urine. For healthy people, little protein will leak out through their urine in every day.

In fact, as the progression of proteinuria, some symptoms often appear in patient’s body.


Protein plays an important role in regulating the osmotic pressure of blood, so when there is massive protein loss through urine, the osmotic pressure of blood will be reduced, and so fluid in patient’s blood will flow into the tissue space. Then, patient will have edema.

When there is massive protein in patient’s urine, patient will have obvious foams in his urine when he urinates. The size of patient’s foams caused by proteinuria is small, and they can stay for a long time in patient’s surface.
