Hi Tabikat,
Have you attended the seminar that most surgeons and bariatric centers require? I got a wealth of information from that. Also you need to check and see if the center where your surgery is being done is a Center of Excellence? Try and find out the success rate, infection rate, and complications of the center. These are all legal and important questions you may ask when the time comes. My center handles all insurance questions, they are equipped to know what different insurance companies require, and since they want to get paid they should let you know what will be required of you and of them.
Remember every center and every surgeon is a bit different. Check and make sure they have a support group, a nutritionist, and check with other patients to see how well they handle any emergency that might arise or if they are available for to answer questions you might have after your surgery.
Most importantly, be an informed consumer. Look on the internet at different sites, learn the different procedures, read some blogs of people who have had the surgery, what type and why they chose that particular surgery. Ask specific questions rather than generalized ones.
This a journey to healthier you and it will pay to be informed. Good luck, welcome to the forum, and let us know how you are doing.
