Hi leesh
I see you are having the same surgeon as me, you will be in safe hands!
As for lose skin everyone is different and how it effects you can vary due to age, skin elasiticity, speed of losing the weight etc. My weight loss has been slow and steady and I wasnt over weight for more than 2 years so I havent really got much lose skin. I have exercised throughout which Im sure has helped plus tried to keep a good skin care routine, scrub moisturise etc.
Not sure if that helps! lol x
