What is proteinuria

summary

I found small bubbles in my urine these days, and the bubbles will not disappear after a long time. I always thought it was caused by fire. As a result, this symptom lasted for a long time. My friends said it was proteinuria. Now let's learn what proteinuria is.

What is proteinuria

First, when the renal function is normal, the glomerular filtration of plasma protein and the reabsorption function of renal tubules are normal, and the amount of protein in human urine is very low. Due to the low protein content in urine, urine routine qualitative examination of urine protein is negative, 24 hours generally not more than 150 mg. When the protein content in urine exceeds 150 mg, it is defined as proteinuria.

Second: proteinuria is a common clinical manifestation of all kinds of nephropathy, primary glomerular diseases such as acute nephritis, nephrotic syndrome, chronic nephritis, including IgA nephropathy, etc. There are also some cases such as strenuous exercise, long-distance March, high temperature environment, fever, cold environment, mental tension, congestive heart failure, etc. can also appear proteinuria, but most of these proteinuria is transient.

Third: there is little protein in normal urine, no more than 7 ~ 10mg / 24h, which can not be detected by routine urine examination. When the protein content in urine increases, ordinary urine routine examination can be detected, called proteinuria. If the urine protein content is more than or equal to 3. 5g / 24h is called massive proteinuria.

matters needing attention

If you exclude the case of functional proteinuria, you should choose a regular hospital for detailed diagnosis as soon as possible. If you find renal function damage, you should go to a regular professional hospital for diagnosis and treatment as soon as possible, and don't wait for late treatment, which will only make you regret.
