Again, take your time and do research.... be comfortable with whatever your decision is...
Also to remember that often for one reason or another, providers tend to not be involved with long term repercussions but ANY surgery, regardless of how minor has repercussions.
For example, I had my tonsils out in 1953 - this was considered extremely low risk surgery and was done routinely.
Later they found out the tonsils are the largest lymph node in the body (store macrophages and produce antibodies) thus people WITH tonsils have a more efficient immune system than those without.
I have been immune challenged ever SINCE my tonsillectomy but I also sustained another repercussion... before the surgery, I was "normal" in weight - being very active I was on the slim side. After the surgery, I began packing on the pounds still being extremely actively and have had a battle royal with my weight ever since. I run 1.5 degrees low in body temperature and suspect in the process of that "routine surgery" my pituitary gland was injured or damaged.
Want another example? I had an esophagoplasty in 1996 when I got something "stuck" (a huge bite of tuna and dry noodles). The surgeon said it would "open things up for 6 months" and then I would need another (I have a hiatal hernia and have suffered with GERD all my life except for the last year when I have been on Weight Watchers).
Sure enough, 6 months later, it got ---worse--- and I started to not be able to swallow pills whole. I was toying with having another esophagoplasty (this is an outpatient procedure - not even considered a surgery) until I happened to meet a guy who had had 9 of them and he was so closed up that he could only eat watery soup.
I decided against the second one....
From that procedure, I sustained scar tissue in my esophagus which means it doesn't conduct the paristalsis wave well and anything which is not very soft or pureed can get stuck. (by the way, chewing gum is a good way to "unstuck" it, I found)
I'm not faulting medicine because they cannot even KNOW the long term repercussions of surgeries but people seem to think they can jump on the table with no repercussions and that just is not true, never true regardless of what surgery!
One program on "Fit TV" called "REBUILT BODY PARTS" (or something like that) showed this guy suffering with infections in his leg from an accident - he had had surgeries etc. Instead of seeking perhaps better or different medical treatment, he decided on his own that the best way would be to amputate the leg. So he had that done. Only he was surprised to suffer the ghost pains (which are excrutiating) and now, he's much less mobile than if he'd just worked with his natural leg.
Whatever tool people use to control their weight is what they will believe in but that's just THEIR experience. That's exactly why I avoid talking up the tool I use, Weight Watchers... it's worked great for me but not great for others.
With that in mind, let me share a couple of things with you...
First, Regardless of what tool you decide on, it will take work on a daily basis. I think all folks here will agree that any weight loss surgery is definitely NOT, "the easy way out". The difference is if you have a permanent change and it doesn't work for you, you cannot go back. Whereas if you have something not permanent like the lap band, if it's not working for you, you can either have it removed and get a bypass or whatever.
Second, I know plenty of folks with bypass surgery who got a lap band over their bypass because they were starting to regain.
As an aside, you may not see folks who are having issues with regain etc in some of the message areas - not necessarily because they are "not welcome" - some places like here are very loving and welcome folks no matter what - but because the INDIVIDUAL feels ashamed and has a hard time SEEKING support. Which is understandable.
Like at the Weight Watchers' meeting this last Saturday after Thanksgiving, we had poor attendance... why... because I think a lot of folks had problems over the holidays.... this is just human nature to do this sort of thing.
But it can be misleading to someone doing research because you tend to think that whatever the procedure, "everyone" is successful at it and this simply isn't true....
Third, an advantage with the adjustable lap band is --- it's adjustable... so "revisions" (which is often the "elephant in the room" i.e. that which is discussed a lot but unseen except in a few places) are non surgical - just adding more liquid to the band.
We had a gal join my yahoo group with a Rose procedure (8 years post op RNY) and she just found out that procedure is only guaranteed for a year.
Here again, whatever tool you get, compliancy seems to be the best bet for a successful journey and often pre ops are NOT told what they will and must do after surgery (why this message area is so wonderful because it better prepares you for whatever procedure you choose).
if you are very athletic, a bypass might work better for you because it IS in place - whereas there are, as I have heard some restrictions on what can be done with a lap band (although, I know lap banders who have done triathlons etc).
But if you are a volume eater, be aware that you can and will be able to outeat the most powerful procedures - we don't volume eat on veggies, do we?

Truth be known, what are the "addictive" foods go down easy whatever procedure you have (or if you don't have a procedure also).
Fourth, the repercussions with a lap band like erosion are not considered "major" and they CLAIM (I have no idea if this is true or not) that only 5 percent or less get erosion... I think that's probably a low figure - those type of estimates usually are...
Fifth, the normal digestion with the lap band can be an advantage but truly? On ANY calorie restriction program, you will likely need to supplement and take plenty of vitamins and even perhaps do protein drinks... even as a NON op I do this. Gads, reality is so much harder than TV stories... don't you see those on the "Biggest Loser" dropping tons of weight "effortlessly" weekly? *LOL* And then you ask them and they're like "oh, I'm just watching what I eat and exercising!" Yeah I actually BELIEVED that for years.... ** sigh **
Sooooo, take your time... there IS NO RUSH. Study study study and get the best thing FOR YOU. You can talk to folks here, perhaps consult a gastroenterologist and find out what might be in store for you in say - 10 years with the different procedures so you make sure there are no dealbreakers in there (this is actually a good idea).
