Question:
Where is iron absorbed?
Hi all. I desperately need to know if iron is "at all" absorbed in the common channel of the BPD/DS people. If you say yes, could you PLEASE give me a site or two where it states that? I just need a difinative answer as I am getting so many conflicting answers. Thanks. — Barbara H. (posted on February 12, 2002)

I have always heard that iron absorbtion takes place in the duodenum. This
is usually good for DS patients since they keep some of their duodenum
fucntioning. I looked up a webpage
(http://www-medlib.med.utah.edu/WebPath/TUTORIAL/IRON/IRON.html) and it
says "Iron is mainly absorbed in the duodenum and upper jejunum."
So no, it's not absorbed in the common channel. The duodenum begins right
at your lower stomach (after the pylorus) and isn't very long I don't
think. The next section of the intestine is the jejunum. I believe the
common channel only consists of ileum (after the jejunum, before the large
bowel). Hope that helps.

I'm the anonymous poster... just wanted to qualify my answer by letting you
know that this is all to the best of my understanding since I am not an
expert. Good luck!

Got a fax?
I'll send you a little diagram of what is absorbed where.
Now, my doc says the duodenum is also bypassed with DS. So, you'd be
missing that as well. Hence the loss of fats/oils.
WE get minute absorption of iron all the way along the intestine, but
especially as the common channel hypertrohpies over time and with lack of
proper nourishement. That's why we can usually head off the kinds of iron
problems you're experiencing with the right iron from the start. And
protein. Protein is always the bottom line for absorbing anything.

I have NEVER heard of any DS surgeon who bypasses the duodenum completely.
It is split, part staying in the food path, hense the name Duodenal Switch.
The old BPD without DS and the RNY does not have this feature.
