How long it takes for urine protein to return to normal is related to the patient’s condition and treatment, etc. There is no specific fixed time.
Under normal circumstances, the glomerular filtration membrane can effectively prevent proteins with a relative molecular mass of 40,000 or more from passing through. Proteins with a relative molecular mass of less than 40,000 will be reabsorbed by the proximal tubule even after they have passed through the filtration membrane. Therefore, the amount of protein excreted in the urine of healthy adults per day is very small, about 30-130mg, and is usually negative by conventional methods.
Therefore, when the presence of urinary protein usually suggests that the patient’s body has a disease, the need to identify the cause of the disease, the treatment of the primary disease, in order to eliminate urinary protein. Since each disease has a different treatment method and cure time, there is no specific fixed time for how long it takes to recover from urinary protein.
Such as urinary tract infection, acute nephritis, acute pyelonephritis and other inflammatory diseases caused by urinary protein, need to actively apply antibiotic treatment, the general course of treatment for 1 to 2 weeks, after the inflammation subsides, urinary protein can usually disappear; renal failure, renal malignant tumors caused by urinary protein, active treatment can only control the rate of development of the disease, can not be cured, the urinary protein of such patients can not be eliminated.
Urine protein may also have other causes, if the patient found positive urine protein, it is recommended to go to the regular hospital in time to improve the examination to clarify the cause of the disease, under the guidance of the doctor to targeted treatment or treatment.
