The average life expectancy of long-term dialysis patients varies from person to person, and the average life expectancy is about 10 years. If the general condition is good without serious complications, and if they usually pay attention to protecting their kidneys, these patients may be on dialysis for a longer period of time, and may even survive for more than 20 years through dialysis. Other patients may be in poor condition or have serious complications, such as severe heart failure, lethal acidosis, myocardial infarction and other life-threatening complications, and may die at any time once these complications occur. And some patients will also develop some of them with the prolongation of dialysis, such as dialysis-associated amyloidosis which can also lead to the death of patients. Patients with short survival may die within about a year or even a few months of dialysis.
