hi there. i have been on hypothyroid meds for like at least 7 years. i too have struggled with weight and my primary recommended i look into vsg. i know some people develop GERD but as sleeve is the less invasive, that is the best option for many people, myself included. you can always revise if you have to, but many people seem to thrive after vsg though each case is unique in its own way. i've been back and forth but i think this is the best option for me and im sticking to my july 20 vsg date. good luck to you!
