There certainly is a postcode lottery.
About 15 years ago, my diabetes care was from a GP who took a special interest and looked after all the PWD in the practice. After a couple of goes round the weight management system, he suggested I consider surgery - at that point gastric band was all the rage and he offered to refer me. It was so emotionally shocking to me that that was suggested, I didn't do anything about it.
A couple of years later, and having moved to a new area, I went to see my new GP and asked to be referred for surgery. He was not keen, talked about lifestyle, going to the gym etc. It took a while - but the following year I adopted healthier eating (cut out most of the **** and ate real foods - but not low carb) and lost 7.5 stone and got off all my meds before I stalled.
Mind you, in the first couple of months, not believe it I could stick with the changes, I researched WLS extensively. I had even decided which operation I would have (gastric sleeve) and with which provider. I was prepared to pay - I think it was around 6K - to have it done privately.
After the 7.5 stone loss and stall, I gradually - much more gradually than ever before - started to regain. Why? Because I let the **** back in. First occasionally, then regularly, then a lot. Over the course of 3 years I regained 6 stone and started back on metformin.
This brings us to my accidental adoption of low carb to " do something about my weight", then the discovery of keto and quite how good it is for managing T2. I've lost 4 stone, and stalled..... but I don't care, because I feel like I've found the key. If I'm destined to still be obese, so be it - I'm no longer morbidly obese, I am mobile and my labs are normal.
But just think - I had one doc try to persuade me to have surgery when I didn't want it, and another dissuade me when I did want it. We are so much in their hands, and at the mercy of their opinions.
