Hey Ali!
Since I had the band with Dr Jawad, I thought I would post and answer. I went into my pre-op and had not lost any weight being on the liquid/low carb diet either. I think they can tell if things have changed by your stats they look at too...and not to worry, I was not 100% perfect on my diet either! I have not heard of him cancelling anyone because of this, but I guess it is possible. The only real reason for the preop diet is not to loose weight, but to shrink your liver a little for the operation, which is why the liquids and low fat diet. So, I would just say to be as good as possible on your last week.
What the other posters say about what goes on during the preop is pretty close, but it is a little different for band vs. RYN. You will go in and speak to Dr J about the procedure and go over the possible complications, expections, diet, and any qestions you have. Then you will go and have your blood work/ekg, etc done. Then, you will go to the hospital or surgery center (where I went) and talk to the anestisiologist so he can examine your throat for the tube, and the nurses can get you into the system and ready. It is a long process, but not bad at all. Ytou will not go over the vitamins like the RYN patients do, as we do not have to take them. Just make sure you have all your questions answered about what to eat and when, and anything else.
If you have any additional questions, feel free to send me a message and I will help in any way possible :) GOOD LUCK!!!
