He feels very sleepy 2 hrs after eating. He seems to be in a downward spiral where he has no energy, yet doesn't feel very hungry. Therefore he doesn't eat much, which doesn't give him fuel....(I tried explaining this to him). He says he feels better after he eats, but then after about 2 hours he suddenly feels very sleepy again. He keeps loosing weight and muscle mass. His balance is getting worse, so he hunches over when he walks (sometimes with a walker) so he won't fall backwards. Generally speaking, this is a man who was very physically active until about age 75. He's had 2 hip replacements, recovered okay from them. My mother passed away almost 5 years ago. The first 2 years he seemed physically okay, the 3 year he slowed down a little and moved to an independent living facility. Year 3 even more so and now on year 5 he seems to be rapidly declining. He says he shouldn't be this way and has sent me the task to "look up on the computer" what is wrong with him.
