I have this terrible process that I habitually go through with new information: 1) learn it, 2) immediately believe that I've always known it, and 3) wonder what's wrong with everyone else who doesn't seem to know it. This is the process I've gone through with peritoneal dialysis, but I think it's high time that I explain what it is and how it works using the simple layman's terms in which I understand it. If you are a medical professional, please refrain from judging my imperfect education and from harshly correcting any inaccuracies. In fact, maybe you should just stop reading now. For the rest of you, here is what I understand the process to be:
There are essentially two kinds of dialysis: hemodialysis and peritoneal dialysis[1] (hereafter referred to as hemo and PD, respectively).
Hemodialysis. Hemo is what most people have heard of/seen, and it's what they think of when they think of dialysis.
