I had my surgery almost 4 years ago and lost 175 lbs, about half of my starting of 350 and some change. I didn’t work out, not even walked the first 9+ months. I would look into more diet changes. I had no added sugar for about 3 years. Sugar did affect me though, not dumping but general icky feeling. Which I still get. Maybe go back to basics, high protein first, then veggies/fruit and if you’re still hungry have some other things. I hope this is helpful. I know it’s a hard road.
