As a side note, without a history of acid reflux or GERD, there is about a 9% chance that a patient would develop it after VSG, and practically 0% after a bypass. That risk goes up if you have any acid reflux history to almost a 25% chance of having serious acid/GERD issues after VSG. I've seen some studies that illustrate even a higher risk. I do have a couple of friends who went forward with VSG even though they had pretty bad reflux issues, and for them, things remained pretty much the same and they chose to manage it, but there is definitely a risk with the VSG which doesn't exist with the bypass.
I felt okay taking the risk since I had no history and my endoscopy didn't show any issues, but I knew it was a possibility going in. It just depends on what your risk tolerance is and if you have other reasons for choosing one surgery over the other. They both have their issues, but both are quite safe, as far as surgeries go. You can also reach your goals though either one.
