I can say that I went through this for about 18 months. I gained 30 pounds along the way. I ate WAY too fast and ate too much. I would not be concerned too much with an eating disorder other than overeating. What happens with folks that are banded is when you eat too much too fast, food gets loged in the opening. This feel very uncomfortable. She is going to the bathroom to "Get it back up". She probably at some point of getting up gets to the point where it all starts going through. Everyone learns how to cheat the band at some point. The band is a tool, just as a tool in your tool box. A wrench can be used as a hammer, but it is best used as a wrench. If your daughter does not want to use the wrench as a wrench, you may not be able to tell her anything. To me it sounds like she needs to see if she is COMPLETELY committed to the program. For me (only a week and a half back on track), I learned if I get a small dish and put my small portion on it, eat it very slow, i feel fuller faster. You will see the trips to the bathroom cease as well. It should take aprox. 20 minutes to eat a half cup of food. Some can eat faster and be ok, but it will make you feel fuller. Also try baby spoons. I know it sounds silly but it helps. Trust me you cant get any sillier than seeing a 31 yr old truck driver (me) walking through a truck stop with a small dish and a baby spoon in hand. We do what we gotta do. I hope all goes well/
