Advice needed. My 80 yr old diabetic father in currently is a nursing home for rehab as he had a car accident 2 weeks ago and prior to that and prior to that heart surgery. When I visited him today he was alone in his room and it does not appear that he is receiving much attention in terms of physical activity. He has lost quite a bit of weight. I feel if he stays there he will only get worse. Any advice would be appreciated. My mother is not acknowleding the severity of his condition. He is on medicare.
