There is no clear data on how many years chronic nephritis syndrome can live, its condition is prolonged and recurrent, and can eventually develop into chronic renal failure, its survival cycle depends on the type of renal pathology, severity and whether to take effective treatment, there is individual variability, and it can generally survive for 2~20 years or even longer. Chronic nephritis syndrome is a disease due to glomerular damage and occurrence of renal decompensation. The main clinical manifestations include proteinuria, hematuria, hypertension, edema and so on. Its condition develops slowly, but it is prolonged and recurrent, and can develop into chronic renal failure. In the early stage of chronic nephritis syndrome, appropriate treatments can be given for its causes, RAS blockers are preferred to lower blood pressure, such as the use of Irbesartan, Benadryl and other antihypertensive drugs to control blood pressure, but also the use of Simvastatin and other lipid-lowering drugs, and aspirin and other antiplatelet aggregating drugs, and strictly limit the intake of protein and salt in the food, and quit smoking and limiting alcohol and so on. Chronic nephritis syndrome can be slowed down and prolong the survival cycle of patients through active treatment. It is recommended that patients with chronic nephritis syndrome should consult a doctor in time and take active treatment under the guidance of a physician.
