You sound a lot like me. I also have PCOS and I will be turning 30 next month. The reality is we all could probably diet and exercise in order to lose the weight but the chances of us keeping it off are low and with PCOS the weight loss is slow and even harder to maintain. For me, my motivation to choose surgery is my children. I realize that the excess weight is unhealthy and I want to be around for a long time for them. Also, I want to have more children and at this weight it would be difficult to conceive. You have to make the decision on what is right for you but I have read lots of posts on here and no one seems to regret their decision to have surgery.
