Urine protein 2+ with normal renal function suggests proteinuria, which is divided into physiological and pathological conditions. Physiological is seen in strenuous exercise, eating a lot of meat, such cases are usually not serious; pathological including chronic nephritis, diabetic nephropathy, etc., more serious, need timely treatment. Physiological: Urine protein may rise after strenuous exercise or eating a lot of meat, which is usually not serious and can return to normal after removing related factors. Pathologic: including chronic nephritis, diabetic nephropathy, etc., this kind of situation is more serious, need timely treatment. Lowering urinary protein and reducing hematuria is an important part of the treatment of chronic nephritis, and commonly used drugs include ACEI/ARB drugs, specifically including valsartan, chlorosartan, captopril, enalapril and so on. Diabetic nephropathy should control blood glucose within a reasonable range. Those who find urinary protein 2+ with normal renal function should go to the hospital in time, clarify the cause under the guidance of professional physicians and get timely treatment.
