Whether or not urinary protein 2+ is important depends mainly on the cause of urinary protein. If it is caused by physiological reasons such as fever, strenuous exercise, etc., after resting, urine protein can turn negative on its own, it does not matter at this time; if it is caused by pathological reasons such as kidney disease, urinary tract infections, etc., if it is not treated in a timely and effective manner, with the progress of the disease, it may be developed into chronic renal failure, which is a more serious problem at this time. If the urine protein is caused by physiological reasons such as fever, strenuous exercise, etc., the patient’s kidneys do not have organic lesions, and the urine protein can turn negative on its own after resting, so it does not matter at this time. If it is a pathological cause such as primary glomerular disease, lupus nephritis, diabetic nephropathy, tubulointerstitial disease and other renal diseases, or urinary tract infections and other diseases leading to urinary protein 2 +, if the primary disease is not timely and standardized treatment, with the progress of the disease, may develop into chronic renal failure, which is more serious. Urine protein 2+ may also have other reasons, it is recommended that patients go to the regular hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
