Keep in mind, the title of this forum is "I Hate Dialysis". I've always considered PD to be considerably less 'hateworthy' than regular hemodialysis is.
I get the impression that most of the hate is directed at uncaring elements of the dialysis industry, whether it's rude staff or aluminum poisoning. The process itself is an invasive medical treatment with all kinds of terrible side effects, but there may be no better alternative.
When I look at pictures of my daughter's first couple of days after hospital admission and dialysis through a neck catheter, she is positively beaming. I don't think she (or we) had any idea how bad she had been feeling for months, despite doing all her normal activities. I have been happy with her care, whether it is the doctors, the hemodialysis staff, or the peritoneal dialysis staff. PD has also made life seem almost normal for now. I also give her a lot of credit for all this, but I understand that not everyone's experience is the same.
