How long can one live when kidney's have failed or at least are functioning less than 10 %? A loved one, on Hospice at home, has good days and bad--serious mental confusion, though knows everyone, just can't remember what took place 5 mins. ago. Carries on conversations but can't begin one at all. In bed 95 % of the day, appetite is small but good--when it's foods liked. Are we looking at days, weeks, perhaps months? At first it was a shock, then we felt it wouldn't be long, but now, with loving care and lots of prayers, our loved one seems to be holding their own. I realize no one knows exactly but do wonder if others have faced this and what comments you may have? Our family member is almost 90. No pain, just feels 'awful' most of the time and is very weak. Not a candidate for dialysis due to heart and b/p problems. thank you.
