There are two kinds of dialysis... hemodialysis requires that a person live where electricity is available and has room for the big blood cleaning machine. Peritoneal fluid exchange dialysis is much more portable, but it swells up a person's abdomen because they hold a solution in the peritoneum that absorbs the toxins usually cleaned out by the kidneys and it is drained and replaced a few times daily.
Thanks, Valerie! I knew there were two types of dialysis, but I didn't know about the abdomenal swelling in the latter case.
That makes a characteristic to look for...IF we ever see a tape!
