Topic: RE: DS or RNY You've already received many great answers, but I wanted to clear up your statement (or maybe just assumption) that the DS is higher risk than the RNY. Not so! It used to be thought that this was the case, but that was during a time when the DS was "reserved" for the heaviest patients, who of course are, as a group, higher risk.
There was an excellent study from the University of Chicago published in 2006 in which they compared 2 groups of patients of comparable BMI and health. One group had RNY, the other had DS. The complication rate was the same for both groups. But the people in the DS group lost more weight, and as time went on the difference in weight loss got larger and larger.
The other issue I'll speak to the the "after 2 years you're on your own" with the RNY. Well, not precisely true. You would never be able to binge eat again because even though the pouch stretches out, it doesn't stretch enough for binging. But there is very little caloric malabsorption with the standard RNY to begin with, and once the pouch stretches out (and it will) there is less restriction, so at some point, all you have going for you is behavioral changes. I used to work with a group of bariatric surgeons who were honest enough to actually tell their pre-op patients that by 18 months, that would be what they would have to rely on. With DS, there is some adaptation of the intestine after a couple years, but never so much that you don't have malabsorption of calories. This is extremely helpful in maintaining weight loss.
I looked very seriously at RNY, read this message board daily, went to a local support group, etc. I found that some people had wonderful success, but many others were in a day to day struggle to keep off the weight they had lost (which often wasn't as much as they wanted to lose) and many were failing at that struggle. I knew that if I had an operation where, after initial success, I had to struggle, I would fail. With the DS, the weight came off easily and thus far (2 and 1/2 years) I have not had to struggle at all to keep it off.
Take a good honest look at yourself. Can you succeed with a low fat, low carb, restricted calorie diet for the rest of your life? Can you tolerate the possible dumping, food getting stuck issues of RNY? No liquids with meals? No NSAID's? Whole catagories of foods you are never supposed to eat again? I looked honestly at myself and knew that RNY wasn't for me. The malabsorption issues of the DS have not been a problem at all. Do your research, learn all you can, be honest with yourself, and then make an informed decision. Best of luck.
