Keeping blood pressure under control does not necessarily normalize proteinuria. It is also necessary to give appropriate treatment according to the amount of proteinuria and the cause of proteinuria. There is a relationship between elevated blood pressure and proteinuria, for example, elevated blood pressure aggravates proteinuria. On the basis of glomerular or tubular injury, increased glomerular pressure (e.g., hypertension) leads to high perfusion and high filtration, which can exacerbate proteinuria. Urinary protein may decrease after blood pressure control, but does not necessarily return to normal. Protein in the urine usually includes glomerular proteinuria, i.e., glomerular filtration membrane damage leading to increased protein leaching; tubular proteinuria, i.e., tubular damage leading to reduced capacity of tubular proximal tubular reabsorption of small molecule proteins; and overflow proteinuria, i.e., a large amount of abnormal proteins in the blood circulation exceeding the tubular reabsorption capacity. If the daily examination suggests proteinuria, it is recommended to go to the regular hospital, follow the doctor’s instructions to improve the examination, to clarify the cause of the disease and symptomatic treatment, so as to avoid delaying the condition.
