Please check out obesityhelp.com but check out EVERY form of WLS.
I had BPD/DS 16 weeks ago, I will forever get to eat NORMALLY, not have to worry about a major weight gain or having a problem with "dumping". As of two weeks ago (as I don't have a decent scale at home) I had lost 58 pounds (in 14 weeks) and had gone from a size 28/30 in tops to an 18/20 and from a 28 scaring a 30 in jeans to a very loose 22.
I can have basically whatever I would like to eat, today I have had: multi grain wheat thins (one serving size) with cheese dip (made with REAL mayo, pimento and shredded colby jack cheese); a steak and baked potato (smothered in real butter, bacon bits and LOTS of cheese); several handfuls of almonds and sunflower seeds, bean dip & corn chips. Geez I don't remember what all else. I over did a bit on the carbs today, but overall you eat as much as you want of proteins, fats and limited carbs until you read your weight goal and then you eat normally. You stomach does very little "stretching". If you gain weight back you go back to post op diet of high protein low carbs for a while and it comes right back off. It has a 98% CURE rate for Type II diabetes as well as several other things. At my 3 month check, my diabetes was GONE, my blood pressure is normal and all other lab work is NORMAL. I'm not used to being 'normal'. LOL
Please anyone who is checking into WLS do your RESEARCH. Yes, the BPD / DS is higher risk, but it is because more people have used it as a last resort type of surgery, where if they had done it FIRST, there wouldn't have to be another surgery down the road. Go to the "revisions" section on the Obesityhelp website to read who has had what kind of revision and why. There are quite a few of lap bands and gastric bypasses who have ended up a year- two years- five years out, on the DS forum getting ready for a revision. I looked at it as a ONE surgery shot, not a "if this one doesn't work, then I can always...."
Make and INFORMED decission!
Good luck with your plans!
oh and here is a good reference for comparison for the RNY and the DS:
