Losing a loved one is never easy, but try to take comfort in the fact that Ray was loved.
He's lost much weight in the past 6 months.
My father was around 5'2, and his "fighting weight" was always around 135 lbs.
When my dad was in his early 80's, he got down to around 100 lbs. The last 4 years of his life living with us he was around 85 lbs. Living with us those last 4 years, I took him to the VA for all of his check ups (and he would go in for regular check ups living by himself up in Pa to the VA). Basically what everyone told us is that due to his age, his appetite slowly decreased and thus the reason why he was losing weight slowly over the years.
It wasn't until he fell and broke his femur and I took him to the emergency room that the medical staff was asking me about his weight. They took him and did some tests on him where they filmed him chewing and his digestive process and showed me the images/film.
Long story short, not certain when it happened years ago, but my father wasn't getting all the food he was chewing in his stomach. I took him in Sunday around noon, and he passed around 4:30 AM Tuesday, and I was with him the basically the whole time and it was a world wind of emotions, and after talking with the doctor Monday asking hard questions and realizing he wasn't going to make it (question only on how long really), so I really don't remember the condition my father was having chewing and digesting. Looked online and I couldn't seem to find anything.
Only point to those with parents who have seemed to lost weight after the years, there may be an actual medical reason. That said, from what I remember being told, the option would to feed him intravenously, which I know my dad would have said no to anyways. Just find it irritating with all the trips to the VA that no one took the time like these civilian doctors did to find what was causing the issue.
