The survival time of patients with advanced uremia without dialysis varies from person to person. If patients do not have obvious symptoms such as breathlessness, severe anemia and oliguria or anuria, they can actively apply medication without dialysis, even oral Chinese medicine and Chinese medicine enemas to eliminate intestinal toxins, and it is possible for patients to survive for 5-10 years. If patients have obvious electrolyte metabolism disorders, such as hyperkalemia, acidosis, low sodium, low chloride, and even obvious oliguria and anuria. 2-3 days without dialysis will show obvious symptoms of heart failure, and in serious cases, cardiovascular and cerebrovascular accidents can occur, and even sudden death is possible. Therefore, the survival time of patients should not be judged according to the late stage of uremia, but according to the specific situation of patients to assess how long they can survive.
