I just got banded on Friday, January 18, 2008 and five days later found out that my band had slipped. It was the most awful pain that I have ever experienced and luckily my doctors were able to determine (after an x-ray) that my band had slipped and had to immediately go into the operating room again. This was all because I did not follow directions when my doctor told me not to eat anything at all. Let me tell you that the slightest most tiniest piece of food can get stuck in your pouch and will cause a lot of vomiting which will, in turn, cause the slippage. I highly recommend that you follow all the instructions and diets that are given to you as this will make your band experience a good one. After the band was adjusted, I felt a tremendous relief being that before it was fixed, I could not hold any liquids at all (including medication) and was dehydrated to the point that I felt extremely weak. Feel free to ask anything you want about slippage. I'm new to this, just as many of us are, but I guarantee you that with my latest experience, I feel now that I am an expert in band slippage.
Good luck to all in your journey!
