There is no one definitive answer to this question as it depends on a number of factors. However, according to the National Kidney Foundation, the average life expectancy for someone on dialysis is 5-10 years. This is only an estimate though and some people may live much longer or shorter depending on their individual circumstances.
Some of the things that can affect how long someone can live on dialysis include their age, overall health, and how well they adhere to their treatment plan. For example, younger people tend to do better on dialysis than older people because they generally have fewer health problems. Additionally, if someone has other chronic conditions like heart disease or diabetes, they may not live as long as someone without these conditions. Finally, sticking to a regular dialysis schedule and following all recommended treatments can help prolong a person’s life on dialysis.
Of course, every case is different so it’s important to talk to your doctor about what you can expect in terms of lifespan if you are starting dialysis treatment. They will be able to give you more specific information based on your individual situation.
