Hello, I just had my gastric bypass surgery on February 12. Is it normal to come home with a 16 lb gain? Is it from all the Iv’s ?

Yes. They pump you full of fluids and consequently everyone experiences some weight gain. It certainly isn’t from what you’ve eaten LOL! You’ll pee it out over the next few days. Make sure you still drink because your body will hold on to that fluid if you don’t.

Totally normal so don't worry

I remember my hands especially were so puffy with fluid. It took over a week just to get back to my day of surgery weight because of all the fluid. But you're still losing fat even if the scale doesn't show it, so don't worry!
