Finally, I'm glad to see a BPD form....

I am considering bpd after weight gain   I had rny in 2004 but have regained about half my weight. Dr marchisni in Brazil seems to be the expert on this and he recommends the bpd instead of bpd/ds. Still doing my research and feeling a bit confused. 

Regaining half your weight after a RNY is normal but doesn't happen with the BPD.  The BPD carries more risks of anemia, vitamin a a,d,e and K deficiencies as well.  Do not have this surgery unless you are willing to eat lots of protein and take vitamins.  I can't tolerate oral iron so I have to get IV iron infusions but I don't think most people have that problem.  Also, be aware of the diarrhea and smell from fat malabsorption.  It is difficult to deal with in my opinion.  BPD does offer excellent long term weight loss and maintenance but there are trade offs.  Plan on getting your gallbladder removed at some point. Be willing to give up sugar if necessary because some people can't tolerate it without a hypoglycemic reaction.  But the positives of sustained weight loss generally outweigh the negatives if you are committed to your long-term health.  

I just bought my plane tickets for Brazil. If all goes well I will have surgery on November 22. Hope all goes well
