Gastric Bypass Surgery Support Group
Gastric bypass (GBP) is any of a group of similar operative procedures used to treat morbid obesity, a condition which arises from severe accumulation of excess weight in the form of fatty tissue, and the health problems ("co-morbidities") which result. If you are considering gastric bypass or have had it, join the community where we share our experiences and find support.

I don't think you're out of line in being upset, but if this is the only center of excellence in your area, I'm not sure what your options are. Perhaps contact someone higher up to voice your concerns and definitely get ahold of your health care provider to stop the financial surprises. I had a financial rep to walk me through all expected expenses on my medical team. Perhaps your team or your insurance company has someone like that.
Good luck and keep on advocating for yourself. You're right to be preparing for a big change, and you'll be glad for the preparations.
Mine was actually very professional and did well though.
I share this often, because I think we can all help each other through our issues and wherever we're at in the process, I have a PRIVATE blog about this past year and a half process if you'd like to check it out :)http://stephnapp.weebly.com/newstephaniejourney
I spent the year and a half telling myself yes...no...yes...no... mayyyybe... LOL but I kept doing all the stuff I had to do in the six months so it was done when I made my final decision. As tough as this road is... it'll be worth it for all of us hopefully.
Good luck with everything!!
