Taking another look at the now and then pictures, I'm inclined to believe the worst. It's a feeling based on a personal experience.
Extended weight loss isn't something that just happens. Granted with the surgery he's had, you do expect some effects as the GI system probably isn't as efficient as it once was. But given the care he's probably receiving, any minor issue should have been resolved. And for any workaholic to have to take time off means that it's probably something serious.
Even with the best care, you can only make a diagnosis based on what you know to test for. You can treat the symptoms but if the underlying cause isn't detected, the best you can do is prolong the inevitable.
Hope I'm wrong cause it's not anything I'd wish on anyone.
