Why does urine have white precipitate overnight

Urine placed overnight white precipitation, showing such a situation is normal, does not rule out the possibility of urinary tract infection. Urine placed overnight white precipitation, most cases is a normal phenomenon, precipitation is caused by the precipitation of crystal substances in urine. Urine generally has different concentrations, a variety of crystal components, urine temperature is generally relatively high, like the human body's 37 degrees, in the case of temperature crystal components dissolved in urine, is not visible, when urine is discharged, with the decrease in temperature. The solubility of crystal components in urine decreases, and it will slowly precipitate to form sediments. In addition, some of them are caused by urinary tract infections. Urinary tract infections are bacterial infections. Bacteria will produce some metabolic products. Therefore, white sediments will also appear in urine.
