Hello, my father is very secretive about his health but has recently become very ill and weak. It transpires he has stage 4 kidney failure and has done for some time now. He has a catheter, water retention, water on his lungs, repeated diahorreah and is incredibly sleepy. He's in a care home. Does anyone have any experience of how this might go for him? We are playing catch up with his symptoms and can't see him because of lockdown
