A person on dialysis treatment for kidney failure has a life expectancy of five to 10 years, the National Kidney Foundation states. However, many patients can live for 20 to 30 years. Life expectancy varies greatly from patient to patient and among health care providers.
Many aspects determine one's life expectancy, and kidney disease has many effects on the body, states the Nephrology Dialysis Transplantation journal. Age, complications after kidney failure, late referral to a medical specialist and a patient's overall health are all factors in determining what damage occurs, which help determine life expectancy.
Dialysis treatment can help treat kidney damage, but cannot cure the disease or replace a kidney, according to the National Kidney Foundation. A kidney transplant is the best long-term option to treat kidney disease and increase life expectancy.
