Urine protein 2+ usually does not heal itself. If urinalysis shows 2+ urine protein, it is usually necessary to carry out another 24-hour quantitative examination of urine protein. Urine protein normally does not exceed 150mg/24h. However, some physiological conditions may also show positive urine protein, such as strenuous exercise, mental stress, etc., but usually does not exceed 1+ and lasts for a short period of time, and disappears after removing the triggers. Urine protein 2+ usually may have kidney damage, such as glomerulonephritis, diabetic nephropathy and so on. It is characterized by a large amount of urine protein, and mainly large and medium molecular weight proteins. There may also be renal tubular diseases, such as pyelonephritis, interstitial nephritis and so on. However, no matter which kind of disease is caused by, it is unlikely to be cured by itself, and it is usually necessary to go through standardized treatment before the urinary protein can disappear. The patient with abnormal urinary protein is recommended to consult a regular hospital and receive standardized treatment under the guidance of a physician.
