There are many reasons for urinary protein, including physiological factors and pathological factors. Normal people can also have urinary protein under special conditions, such as: strenuous exercise, heavy physical labor, mental factors, cold, high heat, eating a large number of high protein foods, etc. In addition, it is also necessary to rule out positional albuminuria. For physiological albuminuria, no special treatment is generally required. After the inducement is removed, albuminuria will disappear automatically within a period of time and return to normal. Generally, it is of little clinical significance and needs re examination. Pathological proteinuria is mainly caused by urinary system infection and kidney diseases, such as acute and chronic glomerulonephritis, nephrotic syndrome, diabetic nephropathy, etc., which can lead to urinary protein. Patients need to do further relevant examinations to confirm the diagnosis.
