Wow, there are so many mistruths in this thread.
1) GBS can be reversed, they just sew back together what they cut apart.
2) The drs do have 1 week, 1 month, 6 month, 12 month, 18 month followups.
3) Going back to old habits is a risk with both surgeries so that shouldn't even be a factor.
4) Even if you lose weight slow, there's no certainty that your skin will be normal. Depends on age, how long you were obese, how much you exercise, Water intake, Vitamins, lotions, and luck!
5) Death rate for both surgeries is about the same, which is actually the rate for most surgeries. 1%. Also varies GREATLY with surgeon experience.
6) Vitamins. Both major WLS options leaves their patients lacking in proper nutrition. ANY 'diet' you start that reduces coloric intake is gonna require you to take your vitamins. GBS people just have to work a bit harder at it cause they absorb 25% less than a normal person.
Meh.. there's more but I'm tired. I'm not defending GBS cause it is truly a big step. I'm just saying .. don't believe everything you hear.
