My uncle is on kidney dialysis because he has such a low kidney function. Once he started the dialysis, he did have more energy, but it can also take a pretty big toll on your body.
He first started out going to a center where he received his treatments a few times a week. Now he does this himself every night at home.
He had to become familiar with the dialysis machine, including the tubing, and what to do if something malfunctioned. There are all kinds of beeps and noises that you have to get used to and become familiar with.
His house is now full of dialysis supplies as this takes a lot when you do this every night.
This is a better option for him though so he doesn't have to spend so much time during the day to receive the treatments.
