Hi and welcome to the forum, Sorry to hear new of your fathers conditions, It can be very worrying for loved ones. I had similar with my aged mother, sadly as some of us get older parts of us just dont work as efficiently and she had many issues with some of her major organs. She also lived with T2 diabetes for decades, which she was forthright in dealing with. But she loved life and the simple things in it. And im sure your father takes great comfort having you around to support him. Its great you are seeking answer on how best to look after your father's wellbeing, its important to be well informed and guided by the medical team caring for him. An idea, If he is willing, (as we did with my mother, especially in her advanced years and increasing immobility) was to make arrangements to have certain people in the family have access to her notes and be able to speak to clinician and her GP openly. It is something you father will have to give permission for, and we found it extremely helpful to us as a family to be able to understand various options for her continued treatments, whatever cropped up. Hope this helps a little.
