I am having surgery on Monday, but I've been a total freak about researching everything including the subject of slipage. This is what I understand:
You are allowed to have liquids for the first 30 days and shouldn't be concerned about calories during this time. The important thing is that you are getting nutrition during this time and are even encouraged to included fruit juices, yogurt, Soups, applesauce, etc. The fact that you ground up a few saltines in your Soup, no big. During this time, I've heard that it is totally normal to feel hungry and to feel like you have no resistance. That's because you are eating liquids. Once 30 days has past and your tummy is all healed, you start on soft foods then move to solids. (slowly) The faster you get to solids the faster you will feel more satified and not hungry.
**** Please, if I am incorrect, CORRECT ME! This is only information I have obtained on the web over the past few months from doctors, nurses and LapBand pts. ****
I am also under the impression that your new 'pouch' is very small. And if you fill it up, it will expand. That is slippage. You don't want to over fill it, ever. It will cause problems that you don't want to deal with like the possibility of another surgery to correct the slippage. It makes perfect sense if you think about it. This band isn't completely tight because you have to create a passage for the food to flow through (stoma), so if you over eat, you could cause unwanted problems.
I think it's best to ask your doctor these questions and ask lots of 'why' questions.
I am still in my research phase and will be for many months to come, but I wish you all the luck in the world and I know you will be just fine.
Wish me luck too!
