Question:
Can someone please explain to me the difference between a DS and RNY? Thanks!

Tracy,
RNY is gastric bypass. DS retains the pylorus and the normal function of
the stomach. RNY has some intestinal malabsorption (depending on degree of
bypass). DS has significant intestinal malabsorption. Here are some web
sites that might be of help:

Hope that helps.
Blessings,

One major difference is that the DS has no stoma issues... which means NO
strictures, no stoma failures etc... If you are blessed with insurance that
pays for the DS I would certainly consider it!

Check out my profile for a detailed explanation of the DS as well as a
plethora of supporting data and links.

As you evaluate the differences between DS (or BPD) and RNY, appreciate
that each procedure has its own particular advantages-- and those
advantages come with decided costs. For instance, the DS offers the most
effective long-term sustained weight loss of any surgical method-- but, it
achieves that result through intense malabsorption, so it carries with it a
greater chance of nutritional issues. The RNY has fewer nutritional
issues (because malabsorption is minimized) but requires greater care in
food choices because of the risks of items getting stuck or being too dense
to be adequately processed without some discomfort. For me, I knew that
maintaining the more intense vitamin regimine of the DS would be an
impossible task (I couldn't remember to take my high blood pressure meds
regularly) and I was put off by the frequent bowel movements that come from
the DS. I was willing to risk experiencing dumping if I didn't make right
food choices with the RNY. For me, the RNY has worked, and worked well (I
dropped 300 pounds in less than two years going from a 62 BMI to a 24.8 in
that time)-- but we all have an individual story to tell of what has worked
for us. The best advice is to listen to your peers and then follow your
heart.

With all due respect to Steve and what he believes about the DS, please
listen to those of us who have HAD the DS. I have essentially no bathroom
issues -- I go once or twice in the AM and sometimes just before bed. The
RNY has now been shown to have MUCH more serious vitamin malnutrition
issues, because DSers can absorb B12 and iron almost normally, as well as
eat substantial amounts of real food; the other vitamins can usually be
covered with a single prenatal vitamin and several calcium citrate tabs/day
(which RNYers have to take anyway). I hate to think what Steve's bloodwork
looks like if he isn't religious about his supplements after having an RNY.
"Intense malabsorption" is somewhat of an exaggeration -- the
term the DS surgeons are using is "selective malabsorption" as,
after the first couple of years, the malabsorption is primarily fat
malabsorption. Please do your research before making a decision.
