My gastroenterologist (who diagnosed my GERD/Gastritis/Esophagitis) wants me to get to normal BMI. For me that's 145, so that's my goal. My surgeon never really discussed a weight loss goal since my surgery was for GI issues, not weight loss.
But I know when I has the gastric sleeve done, my surgeon told me his goal is always for better health for his patients. So he never discussed weight goals, rather things like getting off blood pressure meds, lowering my glucose levels, getting off a by pap machine etc. I did all of that, and he was happy.
