yes - there are fewer complications with the sleeve, but on the other hand, there really aren't many complications with the bypass, either. There's the risk of dumping, but that only affects about 30% of bypassers, and it can be controlled by not eating a bunch of sugar or fat at one sitting (which we shouldn't be doing anyway). Strictures are another one of the most common complications, affecting about 5% of us (if you can call 5% "common", but that does give you an idea of how common complications actually are (i.e, not that common)). That one is an easy fix. And of course you can deal with nutrient deficiences if you slack off on your vitamin supplements. But besides those, complications just aren't that common.
