Personally, I say go with the bypass. But if you're wanting super aggressive, then maybe the SADI is the way to go. How much weight are you lookin to lose? They say you don't lose as much with ANY revision. I got mine because of complications with the sleeve. But I lost 113 pounds in 8 months with the sleeve before all hell broke loose and my complications started. When I had the revision to bypass, I was told to expect to lose 45-50 pounds more, with the high side being 60. Welllll, I've lost 96 pounds since I had the revision 13 months ago...so...yeah. Bypass recovery was a breeze, corrected all my issues, and I kept losing. If you're this anxious and nervous and even scared about the SADI, maybe go with the bypass. You can certainly lose a lot, even though it's a revision. But no matter what surgery you choose, you still have to do the work, stick to the meal plan, track what you're eating, and move your body.
