Being the sole caregiver I am finding all this out about my dad. He has been open about all of his medical needs (a little too open). I have complete access to his medical records and Dr.s My sister is a nurse and she as well. We lost mom last year on the operating table (yes I do blame the Dr., should not have operated on her). Dad is healthy for the most part. Had rheumatic fever at a young age and has an enlarged heart. He said he has a aneurysm on his heart. Nothing they worry about but he ha not had major surgery that I am aware of. He wants his knees repairs. I will take w all the Dr.s but I really don't want to go through what I did with mom when I know I should have talked her out of the surgery.
