Hello - I have had my band for over 5 1/2 years. After about 18 mths my band slipped. I think it was from Throwing up. (not confirmed by My Dr) but I know my body and I was getting sick alot when I ate. But I was willing to go thru this to loose the weight. Bad idea. My Dr took some of the fluid out to see if the pouch would reduce/ the swelling to go down on its own. ( it didnt) One thing that can happen when the band slips is your pouch becomes enlarged, and in my case even part of the old stomach made its way up thru the band, thererfore creating a new pouch from my old stomach. So now I had 2 smal pouches, not a good thing, I was able to hold more food, explaining the reason I was not loosing any weight. So I had surgery to replace the band. Well, just a month ago same thing, but this time I have not been throwing up. However I noticed I was and could eat more then I normmaly use to which also explained some weight gain, I thought maybe I need a fill, I went to the Dr and Bam enlarged pouch, then 2 weeks later band slippage. My band now has to be removed for a 2nd time. Things to learn from my post: You must always remember your band is a "TOOL" never take it for granted. If something doesnt feel right it probably isnt. Check it out...Use common sense, most of the time your Dr. does want what is best for you, seek their advice or call the nurse, they are very knowledgable and have probably heard your worry from many others. Do not over-eat and you should not be throwing-up more then the occasional burp-up. Stay in a support group. Band slippage most of the time can be prevented, sometimes not. For me personally I think the first time might have been preventable, I use to beat myself up over it but now that I have had a 2nd slip, I am not so sure, I didnt throw up. Sometimes it just happens....I will be having a revision surgery this July..not another band, not becuase I do not have faith in the band - I do - it took me down 85 lbs, but My Dr says its time for something else. I will either have the Sleeve or the RYN...5 years ago the RYN was a dirty word to me, now I am prepared, it too is still a tool and I am sure it will get me to goal. Would I do it all over again, YOU BETCHA. Love your band!!
