Proteinuria is a common symptom of Kidney Disease. Therefore, many people worry that they have Kidney Disease when their urine test shows positive proteinuria. In fact, not all proteinuria can prove people have Kidney Disease.
In normal cases, people excrete less than 150mg urine protein per day. If the
execration of urine protein is above 150mg it is called proteinuria. There are
two types of proteinuria: biological proteinuria and biological proteinuria.
Biological proteinuria is also called benign or transient proteinuria. Some
normal people may have proteinuria in cases. But, this kind of proteinuria often
does not last too long. This kind of proteinuria often occurs in the following
For women, leucorrhea and some other secretion of vagina can pollute urine so
they will have protein in urine.
2. Orthostatic proteinuria
This kind of proteinuria is mainly found among adolescents. When they lie
low, proteinuria is negative. However, when they stand or walk, they will have a
small quantity of protein in urine.
3. Functional proteiuria
Functional proteinuria often occurs in some stress states such as high fever,
high temperature, and intense exercise and so on. In this case, the proteiuria
will disappear after the stress states finish.
If your proteinuria does not belong to the above three cases, you are very
likely to have kidney damage. It is caused by damaged renal intrinsic cells.
Under normal conditions, our kidneys can block protein in blood from leaking
into urine. However, if patients have kidney damage, their glomeruli and tubular
lose their barrier function and reabsorbing function. Therefore, the protein
will leak into urine.
Therefore, once you have proteinuria, you should make clear the its reason
firstly. If so, you can adopt relative treatment against its root cause.
