I had surgery yesterday, stayed overnight and have done quite well. I am able to manage fluids, walk off the gas and besides a full feeling in my chest and incisional pain I feel quite well actually. I know I am swollen but to gain 9.5 pounds overnight? I did have 4.5 bags of IV fluid and having some difficulty peeing, but wow 9.5 pounds.

Anyone else experience this?

I had the exact same thing! And trust me, I hated it, and still struggling with the fact that I am not losing at the same rate as everyone else, but the water retention and swelling all went away within a week, just give it time. You will be fine!

You are right. I am sure the weight gain is due to the fluids pumped into you before and afte surgery. Good luck on your journey!

I had my surgery on Friday, went home the same day. The scale was up 4lbs the next morning. This morning when I weighed I was down 8lbs. It's just the fluids they give you, it will come off.
