Whether or not urinary protein 2+ can recover by itself mainly depends on the cause of urinary protein. If it is physiological reasons such as strenuous exercise, after resting, urine protein can turn negative on its own, at this time, positive urine protein can be recovered by itself; if it is pathologic reasons such as glomerulonephritis, urinary tract infection, urinary stones, etc., the urine protein may be gradually reduced after treatment, and most of them usually can not be recovered by themselves. 1. Physiological reasons: strenuous exercise, fever and other conditions may cause positive urine protein, the patient’s kidneys have no organic lesions, no special treatment, after resting, urine protein can usually turn negative. At this time, urine protein 2+ can recover by itself. 2. Pathological causes: glomerulonephritis, urinary tract infection, urinary stones and other diseases can lead to positive urinary protein, active treatment of the primary disease, anti-infection, stone removal or surgery and other symptomatic treatment of urinary protein may be relieved, and can not be recovered on their own. However, some patients with membranous nephropathy or acute glomerulonephritis may have spontaneous remission of their clinical manifestations, and the urine protein may recover by itself. If the patient found that the urine protein 2 +, it is recommended to 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.
