I will give you a brief synopsis of why the DS is better, but then I would like you to go to the DS forum here on OH and read what all the posters have to say about it. It has been proven that with the DS you get a better weight los and sustain it a lot longer. There is more malabsorption for sure, but that is what keeps the weight off better. You would have to take vitamin supplements for life and a bit more than with the RnY. You are able to take NSAIDS, Aleve or Motrin, whatever for arthritis or whatever. A big plus (and if you hated dieting with the RnY) with the DS you can eat more normally and more food. You are not limited to small quantities. Depending on your bowel habits, you may be able to eat carbs and sweets to an extent and not gain weight. Now true, everyone can't do that, but a good many do. The gas issue (if you have heard of it) is usually minimal. Once you find the food culprit for the gas, just eliminate it from your diet or eat that product when you are home and not out in public. A lot of people cannot eat refined sugar or white flour products either, but whole wheat products may be just fine for you. It is trial and error. Also, there are products on the market to quell the gas and poop issues. There is something called probiotics which helps minimize the BM. There is Devrom, which can be ordered online, to help with the smell if it is irritating you or family members. Flagyl, an antibiotic works well for that excessive gas, smell, and poop you may have. Please come to the DS forum and ask questions there. Many who are more pro at this can respond with their story. There is also another website called duodenalswitch.com, which has loads of info for you. Best to you.
