How soon after surgery do you start to lose weight?

Some lose in that first week. Some don’t. It depends on things like how much fluid & gas you were pumped with during & after surgery. How long it takes your body to express it. How your body responds to surgery - the stress. You may have diarrhoea or be constipated over the first week or two. You may retain more of the fluid you’re consuming to begin. It’s all very individual as to what shows on the scale.

Some surgeons actually advise not to weigh yourself for a week or more post surgery to allow for these factors as you can weigh more after surgery than you did before. (I weighed a good 2kgs more 24 hrs after my gall removal & took 4 days to get rid of it.) if you do weigh yourself after surgery don’t be surprised if there’s no loss or if there’s gain. But you could be someone who does have a loss in that first week (I did - almost 3 kg.)

Your weight will be falling off you soon enough after & it will be fantastic. All the best.

^^^^ agree 100%!

I had RNY in 2010. I lost nothing for the first 8 days. It was almost comical since I was barely getting anything in. On day 9, I dropped 7 lbs.
I had a revision 2 weeks ago. I lost 5 lbs the first week, nothing for the past 5 days. I have learned not to sweat the scale too much. I’m feeling leaner, and I know as long as I keep it up, it will come off.

I had surgery on 12/14/2021 and I’ve lost 11lbs since my surgery

I had lost weight when I got home from the hospital. Not everyone does though. The fluids can disguise any loss but I think after a week or two pretty much everyone starts losing.
