Hi and welcome! I think I know who you are.
Having RNY after sleeve makes no sense (though yes, the RNY surgeons are happy to take your or your insurer's money to do what they know how to do and not what makes sense surgically and is going to help you the most). You already have the sleeve portion of the DS. Assuming your sleeve is in good shape, you just need to have the "switch" part added. For RNY, you would need the entire gastric bypass created from scratch, just using your sleeve because that's what's left of your old stomach. You would be having a bigger operation, messing with your stomach unnecessarily, and lose all the advantages you kept when you chose the sleeve in the first place. In other words, you put yourself at risk for dumping (which is NOT a weight loss tool, just a nasty side effect some people get with gastric bypass and not with DS), never be able to take NSAIDs again, lower percentage excess weight loss than DS, more weight regain problems than DS, lower rate of resolution of all major comorbidities than with DS.....
You get the picture.
There are folks here who went to Dr. Esquerra in Mexico both for virgin DS and also for revision of sleeve to DS. Reach out to them and I bet you will get some great feedback about their experiences.
