Shaqsback!

Hi all, New here. I had gastric sleeve surgery Nov 2016, got pregnant a month later. Initial lost 76 lbs. Gained about 20 lbs back at the time of Covid until now. I have GERD and a hitial hernia so I have opted to get a revision to bypass in hopes of forever getting rid of GERD. I never got to my goal weight which was 150 lbs. I was about 16 lbs shy of that. I am about 189 lbs on a heavy day. My concern is that I wont lose as much weight because my BMI is not extreme. Anyone else out there lose more than 20 lbs getting revised being at such a low starting weight? The Dr's office of course says I may not lose any weight at all which I just can believe.
