Hello,
Ok, cannot say in this particular case without directly being there. AND. there's simple tests to work this out.
First, the thoracentesis has a LOT more information than what you can give: if there is inflammation, if there is a lot of protein/blood/cells then there is a LOT of loss of tissue and protein there.
If it is like WATER, then, 1) it isn't cancer and 2) the surgery changes the dynamics and that leads to increased pressure in the area left and forces out water.
Not terrible, fixable with particular diuretics probably but you'd have some
hypotension and his physicians know what they are doing. I can't say, but I suspect they do.
Change in appetite without obvious loss of energy (like with
fever) or tissue (with loss of protein or
glucose in fluid/urine/etc) is usually
depression.
This can be from a lot of medical problems, from the medications or just a lot of happening.
Cardiac
cachexia is easy--there's increased work and just checking the respiration is both the diagnosis and most of the cause.
If someone looks like they've run a sprint, they are burning up a lot of calories. If it isn't OBVIOUS, then it isn't occurring.
Hope I have answered your query. Let me know if I can assist you further.
Take care
