I agree with almost everything you've said....except...they will NOT research her. Medical professionals and their staff have better ways to use their time than checking out potential patients social media accounts. IF she gets to the point where she actually has an appointment, she'll shoot herself in the foot with her big mouth and fistful of excuses. It's pretty simple for trained bariatric medical professionals to pick a hopeless case. I was only ever wrong about one person in many years.
Not being in the US, I'm hoping someone can enlighten me on how the health insurance works for someone like Amber. She said she "applied" and is putting it out in the universe that she'll be "accepted". Is health insurance like life insurance where they take detailed medical history, apply their risk analysis algorithm, then choose to accept or decline. I can't imagine any company insuring health or life etc, taking on a 500+lb liability. Can companies actually turn you down? Where I am (Australia) health insurers put a one year mandatory wait against pre-existing conditions before patients can claim for elective surgery procedures. As WLS is due to obesity, that is considered to be pre-existing so WLS will not be covered by the policy for a minimum 12 months. I also wonder if Amber has any idea about the often massive out of pocket expenses that can be racked up before WLS approval. Most folk here use that 12 month wait to go through all the approval process requirements, as well as save up for the very substantial out of pocket expenses they'll incur.
