I chose the DS (duodenal switch), so I have a Sleeved stomach plus an intestinal bypass to give me the best chance for long-term, maintained weight loss. (And at 8.5 years out, it's certainly working! *grin*)
The great thing about the Sleeve is that it preserves the pylorus and all normal stomach function. It does everything your stomach does now, except hold large quantities of food. In my case, removing 85% of my stomach also cured my constant, grinding hunger. Pre-op, I was, literally, always hungry. Even when stuffed, I still wanted one more bite. Since my DS, I have what I think of as 'normal' hunger---I get hungry, I eat a normal portion, I'm full and satisfied for a few hours.
However---as the Sleeve has become more popular, and as there are more and more Sleeve patients reaching 5+ years post-op---we're seeing more of them showing up on the DS and Revision boards looking to add the second half of the DS (the malabsorption component) due to either insufficient weight loss or regain. While this is a fairly simple revision, it just plain doesn't work as well as getting the complete DS to begin with.
Therefore, I suggest that you also research the DS before you make your final decision. Your surgeon quite likely doesn't do the DS---I don't think there's a vetted DS surgeon in SC. Sadly, that also means he or she may not have given you complete, accurate info about the DS.
Your profile doesn't tell us anything about you---your age, your weight, your medical issues, if any, etc., so what I'm going to say now may or may not aply to you. But if your BMI is high, if you are diabetic, have high cholesterol, PCOS, insulin resistance, etc.---the DS may be a better choice for you. The DS has the very best long-term, maintained weight-loss stats for patients of any size, but especially so for those of us with a BMI greater than 50. It's also the very best at resolving or preventing co-morbs like diabetes and high cholesterol. It has the most liberal post-op eating plan---the average DSer eats around 2500-3000 calories a day, and there are NO forbidden foods, although even DSers must be mindful of their carb intake. (We eat them, and some of us eat more of them than others do---YMMV.)
Think twice, cut once.
