BOB? RNY TO DS? RNY TO RNY? ALL HAVE SLOW WEIGHT LOSS
I don't know that there's a blanket of slow weight loss on revision for everyone. I've seen people lose very well and quick with a second surgery. I asked my surgeon about my particular case going from sleeve to RNY. I emailed him about it and his reply was " current data showed no significant difference in weight loss pattern after sleeve or without it, but the numbers of observation are small".
I wouldn't base my decision solely on rate of weightloss. Just what lifestyle would fit you best. But I wish you luck with whatever you decide!
Do NOT do band over bypass. Just don't. Look at all the failed lapbands out there and the last thing you want it to revise into something with such a high fail rate.
If you do your research thoroughly and find a truly vetted DS to RNY surgeon I would go that route.
I would have revised to DS over RNY myself but my BMI wasn't high enough for my insurance to approve it.
