At least try a diet first. I lost 70 lbs just buying the frozen meals at the grocery store. I wished I had done this many years ago— Lean Cuisine pizzas, etc- Smart Ones- Lean Pockets.
I have a brother who had the bypass in the 80s- he still needs to lose a lot of weight and throws up if he eats too much. I had a nephew that went through it in the 90s and he died in the hospital from a blood clot, which was too common before using blood thinners prior to surgery.
yikes
in other words, change your eating habits - surgery or not
