I’m sorry you are having this experience. Deciding to have WLS is not easy and you should expect your team to be supportive and encouraging. Everyone in this forum will tell you there is no one size fits all (no pun intended) in this process though I can see benefits in a general introduction to the basics of the process in a group class before your individual appointments.
Yes, in Australia it is different and each doctor has their own requirements. Mine requires his patients to visit a dietician before surgery and regularly for at least 12 months post surgery. A much younger friend went to a different doctor and only had to see a dietician once. She is struggling post surgery with her food, trying to take the easy route of takeaways and frozen meals & wonders why she is in pain & vomits a lot. My doctor also recommends therapy but considers each patient’s weight gain/loss history & personal history before making the recommendation. He said I didn’t need to but provided a list of therapists I could see if i wanted pre or post surgery.
My dietician isn’t very good but better than the one I went to years ago who told me I didn’t eat enough. Consequently I put on weight seeing that one - thanks a lot. This one asks what I eat (I just tell her my basic menu), what I weigh and that’s it. Five minutes & I’m gone. No information about calories, macros,... I rely on my own research ( God bless google & this forum) and a friend who had the surgery 12 months before me.
Be patient, keep calm, breathe deeply when attending meetings with your team and follow the steps. Keep up your own research & this forum. Don’t let your frustration with this pre surgery process hinder your surgery. You won’t regret it. Good luck.
