I too had weight loss surgery.
But I think the psychologist evaluation should be done prior to surgery
At OSU it was done that way for me. So my surgery was successful, one because I was mentally and emotionally ready. Plus I prepared my own food . Shopped and made sure I had what I needed.
Counseling to the caregivers is needed. Most importantly to those who are bed ridden. Maybe this is in the show but not shown.
I pray for the candidates but I get frustrated whe they disrespect Dr Now.
Medical staff should intervene and counsel these people on the spot.
Also showing the weight loss math based on their caloric intake
And why they should be able to lose the weight he expects of them
Some patients get right to task but so many more struggle.
More mental help for those.
