You need to "get sick" if you eat "something bad"??
NO, what you need to do is get over the idea that YOU are bad, and that you deserve to be punished for eating food that you like. Being MO doesn't mean you're a bad person. It is not a sin or a character flaw. It's a medical condition. And foods are not evil, there are simply food choices that are better or worse than others. And if you think dumping is a weight loss tool, you are sadly mistaken. It is a very unpleasant, and in extreme cases dangerous, side effect that some (not all!) people with RNY suffer. There is no guarantee that YOU will dump, and if you do, no way to know what foods will cause dumping. Some people dump on sugars, some on fats, some on healthy foods. Some people learn exactly how much of each food will cause dumping and eat right up to that point. And people can, and do, gain weight even if they dump.
You need a totally different mindset to figure out what operation is going to work best for you. It's time to look at the statistics and consider your lifestyle and comorbidities in the equation. So here are some facts for you: the DS (yes, we like the DS around here) has the best statistics of any bariatric surgery for percentage excess weight loss, for maintaining that weight loss, and for resolution of almost all comorbidities. Are you aware that the failure rate for RNY is about 30%, and that "failure" means losing less than 50% of your excess weight? In other words, if you lose just 51% of your excess weight, you're considered a success, and the failure rate is STILL 30%. There are a lot of people who never lose more than 50 - 60% of their excess weight with RNY. Out of all the facts about RNY, the dumping, the no NSAIDs ever again, the laundry list of foods you are never supposed to eat again in your life, it was the failure rate that prevented me from having RNY.
With either DS or sleeve, you can take NSAIDs safely (in proper doses), dumping occurs rarely if ever, there are no forbidden foods, and you retain function of your pyloric valve, just with a much smaller stomach. The "switch" part of the DS creates metabolic changes that work to permanently resolve type 2 diabetes for most (again, not all) people and help with maintaining the weight loss, along with the malabsorption.
I suspect that your research thus far consists of what you heard at some surgeon's seminar. Presumably a surgeon who doesn't do the DS and didn't discuss it. You need to do some real research and learn more about all your options, not get sucked into an operation you think will work by punishing you. No one deserves to be punished for being MO.
