It has been a WHILE
There are alot of bandsters who have had to revise to other surgeries because of slipped bands, band damage and just plain no weight loss. I know of only 2 people who are still doing well Bette and Kate from when I started here 8 yrs. ago. I'm surprised you still have yours actually since they are only designed for 10 yrs but few make it that long. Good luck to you I hope you continue to be one of the rare ones!
A lot of people do revise but you need to be sure why you haven't lost the weight. If it is that in some way the band gave you no help, wasn't enough to help you or caused physical problems, then revising might be a good idea. But if it was that you didn't work with your band, then you need to work out why; I don't know you or your history.
Bette and I may be the only long term banded people who post regularly on here but there are actually quite a lot who simply no longer post - that's not just me guessing, I know them online. I also know a lot of people IRL, although not as far back as 2004! Back to around 2006.
Sorry to hear about all your medical issues; hope they are all now resolved.
