i had my band placed one year ago and have had zero problems. actually that's not true...my only problem is finding money to keep buying clothes!! Everytime i turn around, the clothes i just bought are too big
the band is a great alternative to bypass--less complications, less risk--its simply a safter option, with the same results (if not better...just slower).
its true some people have problems, but the stats are around 1%.
its the best thing i ever did for myself-no regrets. the surgery itself is very easy-i was up and running around 3 days later. you do have to have patience--the band does need to be adjusted and that can take time....i didn't start losing steadily until after my 3rd adjustment, but if you get to goal in 9 months or 12...doesn't matter in the end.
good luck--keep researching!
