Paula,
First of all welcome to the club! I had the same issue with food after surgery and I am one never to lose my appetite. It took about 3 weeks for me to get my appetite back. I just felt full all the time and not hungry.I knew I needed to eat so I would eat very little bits at a time and also light food. My throat got a little irritated from dry food or something that was hard to chew, maybe because of the intubation. I coughed a lot the first ten days which killed my abdomen so I would hold a pillow there for support. I also lost weight and loved the number on the scale; a number I have not seen since and probably won't see till I reach old age and am a frail old woman! Most important make sure to drink. If you really feel like you need more nutrition you can try one of the Ensure types of drinks but you are probably ok to eat small portions and not worry about the eating. As long as you are feeling well, not having nausea, vomiting or diarrhea you should be ok. Some bowels take more time than others to move back into their routine. My body was certainly shocked.
Take care and best wishes for a full and speedy recovery,
Sherri
