Hi everyone - Have't been on here for years, but looking for advice. I have been banded 5.5 years and have had good success with my Realize band. I lost 135 pounds, and over the 5 years have gained about 15 back..which I am ok with.
My concern is that I have always worried in the back of my mind that something was going to go wrong with the band after a few years. I have read and heard other people in the dr. office complaining about complications and having to get bands removed. I read about erosions, slippage, etc. To be honest it freaks me out. It seems like the odds are not good to have a band that never has problems. But really, that is what I have had. I had some issues in the beginning finding just the right fill level, but after that first year everything was pretty good. To be completely honest though, I have always had reservations about putting a foreign object in my body and it's long-tem effects.
What prompted me to post here is that over the past week I have been having some pain in my stomache that feels like a constant ache. I have ruled out constipation/gas, hunger, etc. I am still able to eat normal amounts, and have not been vomitting. But, I just have this uneasy feeling that something is wrong.
I made an appointment with my surgeon/doctor for this Friday, but I don't know exactly what I am going to tell her other than, "something doesn't feel right". I was reading through the "complication" boards to see if anyone else mentioned a constant stomache ache, but didn't really find that. Seeing all the posts about other complications did concern me though.
Now I don't know if I am being hyper-sensitive and anxious when there really is nothing to be worried about, or if I should trust my gut feeling that something isn't right?
I feel like I have always had a pretty good relationship with my band and know how to use it as the tool it is meant to be. Sure, I know how to cheat it, but I think everyone figures that out pretty quick.
I guess what I want to ask are these:
1. Has anyone else had a constant stomache ache?
2. Do other veterans have fears that something is going to eventually go wrong with the band?
Thank you!
