Welcome to the Wrapped Club!
I'm glad to hear your recovery is going well...and don't feel badly...we all overdid it at times!
As far as appetite, I think that is variable depending on the person. Actually at your stage in recovery, not having much of an appetite is probably you body's way of telling you to lay off the food for a while! I'm not saying you shouldn't eat! It's just that your upper GI tract has been through a lot, and your stomach has been pulled, twisted, and stitched. No wonder it's not anxious to have lots of food sent its way!
What has your surgeon recommended as far as eating? Mine let me use my own judgement after Day 6, and set me free to eat anything that could be chewed to a liquid. Many here stay on liquids several weeks, and that's not very appetizing!
I don't think you need to worry about your appetite. Just keep doing your best to take in nutrients--small amounts throughout the day. You will lose weight...pretty much everybody does through the recovery period.
The thing I dealt with was that my stomach filled up with just about a half cup of food. My surgeon said that it is because the stomach is swollen, and it interprets the swelling as fullness. Over time that sensation diminishes until you're back to eating full amounts again. I know I was eating normal amounts by the third or fourth month.
Glad you've joined us. Stick around and share your recovery story!
