Hypertensive nephropathy usually can not be completely recovered, but the appearance of urinary protein reduction or disappearance, urine specific gravity recovery, and the reduction of nocturia suggests that the condition has improved. Hypertensive nephropathy is mainly manifested as pre-glomerular small arteriosclerosis, which in turn causes renal ischemia, leading to tubular and glomerular damage, at this time the damage can not be fully recovered. However, if the blood pressure is maintained within the normal range when actively controlling the blood pressure, and at the same time with low-salt, high-quality and low-protein diet, the tubular damage can be restored, which is manifested in the recovery of specific gravity of urine, the reduction of nocturia, and the reduction of urinary protein, which are all indicative of the improvement of the condition. It is recommended that hypertensive nephropathy patients go to the hospital in time, under the guidance of the doctor active treatment, to avoid the development of the disease.
