LL I understand what you're saying about overpopulation and natures natural removal of crap... that's fine except when you realise that makes us "nature's crap" ! And I know there are many wonderful very much non-crappy people who are on IHD... so i think nature has it slightly mixed up. We're the good bunch who should be saved.....That's some LSD trip mother nature must be on to get it so wrong!!!
There are many on this site who have been on dialysis for many years, and so far as I know, none are "vegtables".
LL,The function of your own kidneys can drop to 0, but as long as you are on dialysis you are still getting the toxins out of your body. It is when the toxins build up too much that the rest of your body systems become compromised and shut down that you become 'comatose' (vegetative state).
