How long you can live without treatment for chronic nephritis varies greatly from person to person. Some people with milder disease, less proteinuria, and relatively slow progression of the pathology type, can survive longer without medication, for more than a decade or even decades. For patients with more severe disease, more proteinuria, and more rapidly progressing pathology types, such as thylakoid capillary glomerulonephritis, if not treated in a timely manner, it may progress to renal failure or even uremia within a few years in the short term and lead to death. Patients with chronic nephritis should visit the hospital in time to monitor their urine protein, 24-hour urine protein quantification, kidney function, blood electrolytes and other related conditions, and should cooperate with their doctors for active treatment. If active treatment is not carried out, patients may have a delayed condition and will eventually die.
