So glad you're home now it's not surprising you lost weight on that awful food nor is it surprising that you may get in some of it back now that you're actually going to eat again. Honestly I think everybody loses weight in the hospital I don't think anybody enjoys that food no offense to the hospital. Try not to focus too much about the weight, but just trying to get better after all you just got out of the hospital that's much more important that you get healthy and feeling better.
