Hey smmrsue,
Our bodies do a lot of weird stuff the first weeks after post-op. Don't worry about the 1 pound. It's just Water weight. If your like I was, you probably are still drinking a lot of broh and Soups and they can be high in sodium. Plus our bodies are focused on healing at this stage....so the gain isn't anything to worry about. I'm a little scale obsessed right now, so I actually woke up and had to go to the bathroon like at 4:30 am and had to step on the scale while I was there. I was very dissappointed to see I had gained 2 pound from the previous morning....I was so upset!! I had such a hard time getting back to sleep. When I got back up at 8 am the first thing did was head back to the scales... and sure enough the 2 pounds were gone.....now I know I had to pee....but not 2 punds worth!!! haha
If you are following the rules, Protein first and watching your calories...its all good and now that you are adding exercise....you are doing a wonderful job!! keep up the great work
Anyway...try to stay off the scale.....it will drive you crazy (like me) and you will be weighing yourself in the middle of the night!!haha
