Length of roux limb?

[minimamaz00m 61]

Hi all and thanks for all the support so far!

After reading all over this board, looking at med journal articles online, and talking to different people on my care team I am 90% sure I'm going to do the Roux en Y (with any luck in Sept/Oct). I have seen a few articles and references to different mm lengths for the roux limb... what does this do? Does shorter mean less absorption = more weight loss? Of course I'm going to ask my surgeon before I make a final decision but I want to have some knowledge under my belt first. Bonus for links to articles online. and THANK YOUUUUUUU

So longer is more malabsorption (bypassed more area)? or shorter (i have a shorter small intestine)?

Hi

I have read a few studies that suggested the longer the bypass does not always correlate to more weightloss except in patients with very high BMI

my surgeon never even brought this up, so I actually have no idea how long mine is.

"The hypothesis is that a distal bypass can lead to better weight loss outcomes due to a longer diversion of the digestive tract and a shorter section of common bowel for absorption.^[11] The small intestine has a huge variability in length among patients and can vary between 300 to 1,000 cm.^[12] Because of this, the CL length can theoretically range from 50 to 850 cm in a proximal gastric bypass as intestinal lengths are not routinely measured before reconstruction of the digestive continuity."
