You may get tired here or there and need to take a little break to give yourself a rest. Make sure your boss knows of your condition. The biggest problem seems to be scheduling. Because hemodialysis takes up a lot of time, it may prove difficult to arrange a work schedule around your treatment time. Peritoneal dialysis can be done nearly everywhere, so some people prefer this modality of dialysis.
Many states have work rehabilitation programs.
These programs can help if you cannot continue to work where you once did. They can train you for something else and help you find a new job. Dialysis will be a big part of your life, but it will not be the only part of your life. I look at it like a part time job. You can still do everything you always did before dialysis.
