I've said it before and I'll say it again.  75% of the dialysis patients at my unit are there from mismanaging their beetus. There's about 300 of us. Three fucking hundred. It's a horror show during the day. I'm a rarer noctunal patient, so I go overnight, which is saved for the 'healthier patients', but during the day it's scary. Old, decrepit, monstrously fat, bloody sores, missing legs, missing arms, blind people, everyone's in a goddamn wheelchair, people crying, screaming, puking, infected everything, bruises covering their entire bodies, bloated guts, swollen faces, fingers missing, cops showing up because inevitably some patient says they're going to kill themselves and the cops have to be called, machines beeping non stop... bathrooms full of shit and piss (always baffled me, most dialysis patients don't pee at all), nurses running around frazzled, it's a nightmare.  For some reason though I feel like even if you made a documentary about how horrible renal failure is I still don't think the fats will change their ways.  All of them have the 'won't happen to me mentality', but guess what? It does!
