I think this is one very hard question to answer since we're all
different in our beginning weight and surgery types.. Seems to me That I
see those that are the Super obese loose greater amounts faster.. I'm
not even one year post-op Yet... I'm just 10 months post-op and I have
lost 170 pounds.. That's about 78.5% of my excess weight gone so far... My
beginning weight was 367 and I'm now 197 pounds.. My goal is 150.... The
pounds are still steadily melting off. I eat very normal meals.. My
caloric intake is between 750-850 calories as a normal, however, some days
900.. I feel great, best I have in over 20 years and I have not been under
200 pounds since I was 17 years old..

My RNY surgeon says this: MOST patients lose 40% of their preop weight -
on average. Of that total loss, 50% is usually lost by 5 months then the
other 50% is lost over the next 12 months. Hope this helps you.

Well, I think that the rate of loss averages about 80% of excess weight
within the two-year window after the DS (duodenal switch, also referred to
as the BPD/DS - bilio-pancreatic-diversion/duodenal switch). This is
according to a 10-year follow-up survey by Dr. Hess, in which he quotes:
"here is an average maximum weight loss of 80% excess weight which
occurs at 24
month post-operative and continues at a 70% level for eight years."
(http://www.duodenalswitch.com/Procedure/DS_vs__RNY/1998Hess/1998hess.html).
In a 1993 report by Marceau comparing the older BPD surgery to the improved
BPD/DS, he quotes: "Weight
loss after either operation was greater thjan 70% of the inital excess
weight. Following the new
operation, there was a lesser prevalence of side effects, especially
loose stools and
malodorous gas, a lesser degree of hypocalcemia and no
hypoalbuminemia....The prevalence of side effects and the degree of calcium
and protein
malabsorption remained significantly lower. Weight loss remained
satisfactory with a common
limb measuring 100 cm."

This procedure isn't as common in the US, but it is an option and can be
done laparoscopically by a few doctors in this country. :)

I have a distal gastric bypass. I lost about 130 in the first year, and
the balance after my tummy tuck at 13 months. So by 18 months, I had lost
150 and was at my goal wt of 112 or so. With these very distal procedures,
I've seen women lose as much as 210 in a year, men over 300! Wow, huh?
And being distal, we tend to hold goal wt without too much effort.
