The number of people who can live with chronic nephritis varies from person to person, some patients may develop chronic kidney failure or even die within a few years; some patients with chronic nephritis develop more slowly and their condition is relatively stable for more than a decade or even decades. The time of survival of chronic nephritis is mainly related to the type of pathology of the patient, whether the patient timely medical care, whether the usual attention to protect the kidneys and other factors, such as the patients with capillary glomerulonephritis progress faster, for patients with membranous nephropathy progress more slowly. Some patients with nephritis seek medical attention in a timely manner and are very cooperative with the doctor’s treatment, so their condition may develop relatively slowly. Some patients do not pay enough attention to the disease, and do not regularly follow up and cooperate with the doctor’s treatment, so the disease may develop more quickly. Patients with chronic nephritis sometimes do not pay attention to protecting their kidneys, such as infection, fatigue and the use of nephrotoxic drugs can aggravate the damage to the kidneys.
