Why is urine cloudy?


Slurry urine is often caused by glomerular disease and urinary tract infection. To know the exact cause of the disease, the patient needs to see a doctor to check kidney function and urine test. Here are some key facts regarding the pathophysiology of cloudy urine:

1. Urine contains protein that makes urine cloudy


Urine in healthy people changes color from light yellow to dark yellow depending on the amount of water supplied to the body, but absolutely no urine scum. However, for some reasons, the glomerular filtration rate is reduced, which will make large substances unable to pass through the filter membrane, resulting in being excreted in the urine, including proteins. Slurry urine is very consistent with the symptoms of proteinuria. In addition, to show that there is protein in the urine, you can add vinegar or sulfosalicylic acid to the urine, there will be precipitation and cloudiness.
Proteinuria is a sign of kidney damage. In general, positive proteinuria is common in the following cases:
