@ShmittyInVegas you need to step back, take a few deep breaths, and do some deep thinking before you have a surgery you will be stuck with for the rest of your life. If you think it's tough getting insurance coverage for a first bariatric surgery, you should see the pain people go through to get coverage for a revision - often without success. And RNY to DS revisions, in particular, are the toughest to get because it's a huge and high risk operation that very few DS surgeons do. So for the short term good feeling of "I'm finally doing SOMETHING" you will put yourself into a much worse long term problem.
I don't know whether or not you will be able to find a DS surgeon who accepts your present Medicaid insurance. However, it sounds like you may have other possibilities for insurance coverage that you never explored - you just took what was handed to you. That isn't criticism, you had nothing for 10 years and at that point having at least something looked good. Now that you know more about the limitations of what you have, you could learn more about your options and maybe find something better.
You, and everyone else considering gastric bypass, need to know that the long term failure rate is very high. "success" is defined as losing just 50% of your excess weight, and even with this very generous definition of success, the failure rate for gastric bypass is about 30%. And that doesn't even account for all the people who lose between 50-60% of their excess weight and struggle to even sustain that degree of "success". Those results were what kept me from having gastric bypass, even more than all the unpleasant side effects people life with. If those results are acceptable to you, fine, it's your life.
Desperate people do desperate things. When you are drowning and someone throws you a rope, you don't stop to examine the quality of the rope and how long it will hold you, you just grab onto it and tell yourself it will hold. But this time, you know better.
