Depends on your surgeon, how extensive their program is, and what your personal medical history indicates. And what your insurance company's requirements are, or if you're self pay.
My "big picture" looked kind of like this:
Go to info seminar
Fill out surgeon's paperwork
Submit medical records along with paperwork
Wait for notice of pre-approval
Upon notice of pre-approval, get list of things to do from coordinator:
- Attend one support group meeting pre-op
- Psychologist visits (number of visits TBD by psychologist)
- Lab work
- Chest x-ray
- Meet w/ dietician for overview
- Meet w/ bariatric coordinator for education session
- Meet w/ surgeon for consultation, which is also when surgery date was selected
Numbers 1 - 7 occured in no particular order. I got in when I could get in, and did the things that didn't require much appointment notice in between. I ended up having my admittance work done 3 days before surgery, and my last psychologist visit the day before. :)
If I'd had comorbidities, there might have some additional steps for testing - e.g. sleep study, etc. If my insurance company had required 6 mo medicaly supervised diet, there would have been a step for that. Which is why there is no one "this is how you do it" approach.
Best of luck!
