Hi Rose😊 Welcome!
There's heaps of great info on here that you can check out! Try the 'All about surgery' and the monthly sections for some blow by blow information. As for your specific questions...
I had my surgery done in Sydney in March 2015 with no complications and no complications since.
I have met a few people who have had complications and they can be major life threatening issues so make sure you do discuss this with your surgeon so you know the risks and what to do to reduce them in your own case.
I didn't see a psychologist for a huge period of time but I do think it would be very beneficial, I have had a hard time adjusting to the mental side of losing my coping mechanism with food (I am an emotional eater). If you can work with a psychologist to put good strategies to cope with stress in place I think your journey would be that little bit easier.
Can't help with dietitians in Melbourne😉
Last point...yes getting the sleeve was massively life changing! And it has far exceeded my expectations! Before the surgery I really wanted to believe that it would help but I don't think I ever truly thought I would get the results I have achieved😃
I've lost over 36kg (over 75% of my excess weight) and am maintaining that while building muscle, I've completely changed my relationship with food and I'm a much fitter and healthier version of me💪
Was it easy? No freaking way! But it has been so much easier to make food choices because after the surgery I finally got why people can sit there and say 'why can't you just stop eating?' Before surgery I could lose weight but it was always a struggle eating small amounts and I always felt deprived, I always regained because I just couldn't rely on will power for the next 40 or so years to keep it off. NOW I can stop immediately, I eat what I can physically eat and just don't want anything more. I can literally stop mid bite and say nope I'm full I don't need anything else! And that is the massive difference, I don't feel deprived anymore!
There are things I don't eat since surgery but the list is very short. I can pretty much eat small amounts of everything and I still go out and enjoy eating food with friends! I don't really like steak anymore or yogurt and I don't do soft drinks, those foods don't really sit great. I try to avoid bread, rice and pasta because they fill me up but don't have a lot of useful nutrition but on the whole I eat pretty normally just healthier and heaps less than I used to.
You have to commit to the lifestyle changes, it's a tool not a majic wand so be prepared that it's going to be hard work! That said for me it has been a great solution to my life long issues with my weight and the best decision I've made.
Whatever decision you make in I hope you get the support that you need and I hope it all goes well😊
