How long you can live without dialysis is mainly related to the severity of uremia and the patient’s physical condition, age and other factors. Uremia is mostly due to the impaired kidney function of the body caused by the decline in glomerular and tubular function, resulting in abnormal changes in human organs caused by the failure to effectively discharge metabolic waste in a timely manner. Patients in the early stage of chronic renal failure have no obvious symptoms, and some of them have clinical symptoms such as lumbago, weakness, loss of appetite, etc. The survival period of patients through conservative treatment is about 3-5 years, and the survival period of young patients with good health is more than 5 years; patients in the late stage of uremia have serious clinical symptoms such as nausea, vomiting, respiratory distress, etc., and may have myocardial infarction, heart failure and other combined diseases at any time, which seriously threaten the life of patients. Patients’ lives are seriously threatened. Patients with advanced uremia must go to the nephrology department of regular hospitals in time and actively undergo peritoneal dialysis treatment or replacement therapy to prolong their survival.
