Re: Abdominal surgery
You don't mention what type of surgery but, if it involved his colon in some way, his bm's will be funky for a while. His appetite is probably not the greatest at this point.....a combination of the surgery itself and narcotic pain relievers, which suppress the appetite.
Still, for some peace of mind, call the surgeon's office and express your concerns. Have him eat lots of protein, which helps healing. I lost weight immediately after my colon surgery but my appetite came back full force....and am now on a diet to lose some of the extra pounds!
He's still very early in his recovery after a very major surgery, and will feel all sorts of twinges and discomfort in various areas. Each week gets better!
Good luck to him,
