I also have no stomach hunger. I had 18” of my sigmoid colon resected due to severe diverticulitis. I just chalked it up to that surgery, but you mentioned Covid does do damage to the Vegas nerve, as I also have no taste or smell. I don’t know if the loss is from Covid or from my surgery. My doctors are telling me it’s from long covid. I’ve had 2 Stellate Ganglion Block injections to regain my taste/smell and it has helped a little bit, but I still can’t get any flavors, only sweet, salty, sour or bitter, but it is stronger than before the injections.
