Urine concentration is not necessarily followed by urinary protein, it needs to be determined on a case-by-case basis. Urine concentration mainly refers to a significant reduction in the amount of water in the urine, the waste products and components in the urine may gradually increase in the body, the frequency of urination can be significantly reduced. The occurrence of this situation may be related to the usual low water intake, sweating more in hot weather, diarrhea resulting in excessive water loss, etc., but does not necessarily produce urinary protein. Urinary protein mainly refers to the protein present in the urine, which may be associated with the development of nephrotic syndrome, diabetic nephropathy and other diseases, and is related to the damage to the glomerular filtration barrier. Usually, it is not possible to determine the presence of urinary protein through urine concentration. It is recommended that patients go to a regular hospital for kidney function tests, have their condition evaluated by a professional doctor, and follow the doctor’s instructions for targeted treatment.
