I’m also in Washington. West side. I’m one week post-op. I also lost a large amount (53lbs) before surgery. I freaked out a little after surgery when I first weighed myself. I gained 8 pounds in the 3 days in the hospital. There’s no way other than retaining water. One week post op and I’m back down to my pre-op weight. I know it’s hard to turn off that part of your brain that’s been trained to watch your weight for so long, but it really is for the best. Just stick to your plan. Hope that helps.
