Dialysis is a life-saving remedy for people with end-stage renal disease (ESRD). Kidneys are important in filtering waste products from the blood and adjusting the body’s fluid and mineral levels. When the kidneys are not working correctly, waste products accumulate in the blood and lead to serious health problems. 

The effectiveness of kidney dialysis depends on various factors, but in general, dialysis is a process that removes waste materials, toxins, and fluids from the blood when the kidneys are no longer able to do so.

There are two major types of dialysis: peritoneal and hemodialysis. Hemodialysis is usually performed three times a week in a clinic or hospital. Peritoneal dialysis is performed at home, and the inner layer of the abdomen is used as a filter.

Maximum life expectancy after dialysis according to statistics

Life expectancy for people on dialysis has improved significantly over the past few decades. In the 1970s, the average life expectancy of a person on dialysis was five years. Today, the average life expectancy is 10-15 years.

Many factors can affect the life expectancy of a person on dialysis, including the age of the patient when starting dialysis, the type of dialysis, the patient’s general health, and his adherence to dialysis treatment.

According to the USRDS Annual Report of the United States Renal Data System, the first year of dialysis carries the highest risk of death for dialysis patients, and life expectancy improves for those who continue treatment after the first year.

A study that examined the relationship between the performance of hemodialysis centers and mortality by Port et al. (2001) explains well that various factors affect the mortality of dialysis patients, including the quality of the dialysis center, frequency, and duration. Treatment time, patient’s demographic characteristics, age, gender, race, concurrent conditions of diabetes, cardiovascular disease of the patient, and adherence to treatment protocols.

In the following, we will examine various factors that will affect the life expectancy and longevity of dialysis patients:

  • The effectiveness of different dialysis methods

A study comparing hemodialysis and peritoneal dialysis mortality in the United States by Weinhandel et al. (2010) found that PD patients initially had lower mortality rates, but over time, mortality rates converged. Patient selection and clinical factors significantly influenced these results.

If you need more information in this field, refer to the article “Which is better, PD or HD?“.

  • The effect of dialysis initiation timing on life expectancy

A study by Cooper et al. investigating early dialysis initiation and mortality in patients with “stage 5 kidney disease” confirmed that early dialysis initiation before the onset of severe symptoms did not improve survival compared to later initiation. Optimal timing should strike a balance between risks and benefits according to the patient’s individual health status.

  •  The effect of home dialysis on life expectancy

A study titled “Survival with home hemodialysis, a systematic review and meta-analysis by Nitesh et al. (2011)” explains that patients who undergo HHD home hemodialysis often experience better survival rates than patients who receive in-center hemodialysis. Factors influencing better outcomes include greater flexibility, more dialysis sessions, and improved patient quality of life.

  • The effect of economic and social factors on life expectancy in dialysis patients

According to a study titled Socio-economic status and mortality in dialysis patients conducted by Kimel et al. (1998), low social and economic status is associated with a higher mortality rate in dialysis patients. Access to health resources, nutritional status, and social support play important roles in patient outcomes.

  • Technological advances and longevity of dialysis patients

In a study that investigated the impact of technological advances on mortality and maximum life expectancy of dialysis patients, Tentori et al. (2009). It is explained that technological advances such as dialysis machines, water purification systems, and vascular access techniques have contributed to a gradual decrease in the death rate in recent years. Continuous innovation and adherence to best practices are essential to improve patient outcomes.

These studies show that several factors, including medical, social, economic, and technological aspects, affect the mortality of dialysis patients.

  • The effect of more dialysis sessions on the life expectancy of dialysis patients

. A study titled “Effects of frequent hemodialysis on mortality and clinical outcomes” by Saunders et al. (2016) shows that patients with weekly dialysis sessions have a higher life expectancy. Increasing the number of dialysis sessions can improve kidney function. Better support and reduce complications related to dialysis.

  • Reduced life expectancy due to cardiovascular complications

A very important point has been addressed in a study titled Cardiovascular Complications in Dialysis Patients Predicting Mortality by Goel et al. Dialysis patients are in high danger of cardiovascular complications such as heart attacks and strokes. Which is one of the main causes of death of dialysis patients. Therefore, careful management of cardiovascular risk factors It can help improve survival rates.

  • Death in nocturnal dialysis

The findings of research by Jennings et al. (2012) show that nocturnal dialysis, during which patients are dialyzed during the night, improves the quality of sleep and a better balance of body fluids, lower mortality, and higher life expectancy. has shown

  • The effect of gender difference on life expectancy in dialysis patients

In a 2003 study, it was shown that female dialysis patients generally have a lower mortality rate and, therefore, a longer life expectancy than men. This difference may be related to the biological factors influencing disease management and health behaviors.

  • Life expectancy in elderly dialysis patients

Findings Older dialysis patients have a higher mortality rate than younger patients. However, the quality of life of elderly patients can be improved with careful management and supportive care.

  • The effect of chronic diseases on the life expectancy of dialysis patients

Dialysis patients who have other chronic diseases, such as diabetes and high blood pressure, have higher mortality rates. This conclusion, which came from a 2011 study, suggests that the simultaneous management of these diseases can significantly increase life expectancy.

  • The effect of race and ethnicity on life expectancy

According to research data in 2004, race and ethnicity can affect the length of life in dialysis patients.

 For example, black patients live longer than white patients due to genetic differences and social and economic factors.

  • The effect of nutrition on the longevity of dialysis patients

Patients with proper nutrition and high serum protein levels will live longer. Therefore, proper nutritional programs can help improve results.

  • The influence of psychology and social support

Patients with stronger social support and better mental health have a lower mortality rate. Therefore, providing psychological support and creating support networks can help boost dialysis patients’ quality and life expectancy.

New research has good news for dialysis patients.

Exercising during dialysis, in addition to reducing complications and cardiovascular problems in kidney patients, increases the quality of dialysis and improves nutritional status.

Exercising during dialysis prevents patient muscle wasting, improves osteoporosis and anemia, and reduces inflammation.

Currently, 15% of the world’s population suffers from kidney disease, and this disease is one of the most common diseases that is increasing day by day due to the sedentary lifestyle that is spreading among the people of the world, as well as improper nutrition. Becomes According to the research conducted until 2040, kidney disease will become the fifth cause of death in the world.

It goes without saying that among kidney diseases, kidney stones are the most common kidney disorder that can be easily treated if diagnosed on time. By reading the article “What Are The First Signs Of Kidney Stone?” You will be able to take timely action and avoid irreparable risks.

Although kidney disease can be controlled if detected in the early stages. However, there are many people whose disease is extended to the stage of dialysis, and these patients are walking on the red line between life and death. if they cannot have a kidney transplant, their life will not last more than five years on average.

In the article “Can Kidneys Start Working Again After Dialysis?” We have talked about this in detail.

The good news is that researchers emphasize that exercise during dialysis can reduce fatigue, depression, hospitalization, sleep and nutrition quality, and patient quality of life.

During the research that the researchers recorded, it was found that exercise during dialysis improves factors in the patient’s body that increase the success rate of the transplant operation, and the patient’s body accepts the transplanted organ better after the transplant operation. Slow and faces fewer problems.

Therefore, in addition to the use of medicine, exercise during dialysis should become a therapeutic requirement and should be performed according to certain standards and under the supervision of a sports physiologist to make life easier and more beautiful for the patient.

Problems of elderly dialysis patients and its effect on life expectancy

Kidney dialysis in kidney patients causes complications, which may be more common in elderly patients due to having other diseases. Among the most important and significant complications of this disease are the following:

  • Malnutrition

    One of the most important complications of kidney patients undergoing dialysis is malnutrition, which is more common in elderly patients.

There are various reasons for the occurrence of malnutrition in these patients, such as constipation, continuous and frequent hospitalizations, side effects of drugs, depression, and lack of proper information on the nutrition of these patients, etc. are some of the reasons for malnutrition in these patients.

  • Infection

    Elderly people undergoing dialysis treatment are more susceptible to infection due to disorders that occur in their immune system as well as constant malnutrition.

The most common infection that occurs in these patients is vascular infection. Infections have a great impact on reducing the life of these patients, so it is very important to pay attention to it.

  • Gastrointestinal bleeding

    These patients are highly exposed to gastrointestinal bleeding. Gastritis is one of the most important and main reasons for bleeding in the digestive tract of these patients.

  • Depression

    Dialysis patients are highly prone to depression. This complication is so important that not paying attention to it can lead to hospitalization and even death of these patients.

Therefore, you may be discouraged from this treatment and want to stop it. But our advice is to try to control the side effects of dialysis because stopping the treatment will have very serious problems for you.

Frequently asked questions

What can I do to improve my life expectancy?

There are many things you can do to improve your life expectancy on dialysis, including:

  • healthy diet
  • regular exercise
  • Quit Smoking
  • stress management
  • Take medications as directed

Can I stop dialysis?

In most cases, people with chronic kidney failure must engage in dialysis for the rest of their lives, but people can stop dialysis after a kidney transplant.


How is the quality of life in dialysis?

Quality of life on dialysis can vary depending on various factors, however, many people undergoing dialysis can lead an active and fulfilling life.


Does dialysis increase the life expectancy of the elderly?

Nowadays, due to the fact that the age of the population is increasing day by day, the number of elderly people who suffer from kidney diseases is also increasing, and these people need a kidney transplant or dialysis to compensate for their kidney failure. 

You should note that kidney transplant is not the end of the story and Kidney Transplant Aftercare will be very vital.

On average, the life expectancy of people over sixty-five years old and suffering from kidney disease is between 3 and 5 years, which is much lower than the life expectancy of people who do not suffer from this disease and are under. They are not included in the kidney dialysis process. In general, increasing age has a direct effect on reducing the life expectancy of dialysis patients. 

Elderly people are more concerned by doctors because of diseases other than kidney failure, and they always recommend that these patients be visited regularly to prevent depression.
