How long a person can live with uremic encephalopathy varies from person to person, and it is mainly related to whether the uremic encephalopathy is treated promptly and the severity of the uremic encephalopathy. If uremic encephalopathy is severe and timely treatment is not performed, patients may die within a short period of time, or even within a week. If timely treatment is carried out and the patient is treated better, the survival time may be longer. Generally, after uremic renal replacement therapy, the survival time can reach about 5-10 years, or even longer survival time. The pathogenesis of uremic encephalopathy is not very clear, and is considered to be related to a variety of factors such as high toxin levels, secondary hyperparathyroidism, and electrolyte disturbances. Therefore, for the treatment of uremic encephalopathy, the first thing is to remove toxins in time. The treatment of toxin removal mainly includes three methods: the first one is hemodialysis, peritoneal dialysis and kidney transplantation. Secondly, patients are advised to take rest and have a low protein diet. The third one is to correct the disturbance of the patient’s internal environment in a timely manner.
