The choice (RNY) was made for me by my doctor. Pre-op, I had bad reflux issues. The Gastric Sleeve has been known for increasing these issues. Since the surgery, my reflux is a very rare thing. Also your BMI can be a factor in the surgery type.

RNY has better initial fat% lost at 60-80%, versus the sleeve's 50-70%.
RYN fat loss is faster, but only during the first year. At 3 years time, the fat loss rates are very similar.
RNY also has the increased likelihood of creating "Dumping Syndrome" over the sleeve. Dumping sounds horrible, but it's a very effective deterrent that can be used as a tool to curb overeating and poor food choice (sugars/carbs).
Sleeve removes a portion of the stomach where the majority of the hunger hormone ghrelin is produced.
Bypass creates more mal-absorption, which means you absorb less calories, but it also means you need more vitamins to keep up.
Bypass is more complicated surgery. It takes a little longer than the sleeve. You will be KOed for it, so it is kind of a non-issue.
Sleeve's slower weight loss COULD lead to less skin sag. The skin has more time to adjust to the weight loss. I say COULD, because genetics play heavily into this, as does age.

These are just a few things I remember. If I think of more, I'll try to post up. There's also a LOT of info on the web regarding this.

He explained that if you like sugar, having RNY will eliminate the "want" mostly because if you do eat something high in fat or sugar, you will dump.

I hate that I didn't end up with D.S.

I chose RNY because I wanted the bypass/malabsorption. I see this as a "bit more help". I do not have dumping syndrome...based on some things that I've eaten (cheese and no sugar added foods). I'm very picky with what I eat nutritionally, but I've had small servings of things with a bit of fat and sugar. Who knows...maybe I'll get dumping syndrome if I eat something super stupid...I sure hope so!!

If you would like, you can check out my website where I blog weekly. It describes what I've faced and I'm very open with my experiences. I LOVE my new plumbing. BEST DECISION EVER! I also love never having acid reflux any more!

I chose the sleeve because I wanted the least invasive procedure. I originally went in wanting the lap band because I read that it was reversible, but my surgeon told me he wasn't doing them anymore because he was seeing more complications than benefits. I went back & forth with the dumping issue when I was considering which procedure to get. The dumping was actually a positive in my eyes--just one more thing to keep me from going off track. In the end though, the malabsorbtion was the deal breaker. I am a very picky eater & figured I didn't want any more limitations on what I ate & needed to absorb every last nutrient that I can. Because of my pickiness, I do end up taking a bunch of vitamins because of deficiencies. I am glad that I am allowed to swallow pills rather than having to find chewables for everything.

With respect to dumping syndrome, my personal experience is don't be afraid of it. It clearly is different for everyone, and for me I'll just feel "yucky", maybe break out into a cold sweat, and mostly it's an uncomfortable reminder that I knew I would regret that dessert or glass of wine.
