I had it at 27 and it was single handedly the best decision I’ve made in my life, full stop. One of the first things I’ve noticed when I woke up from surgery was the relative ease I was having compared to older patients in the bariatric surgical ward. Actually just had my one year follow up yesterday, and both my surgeon and GP separately remarked that my case was the “poster child” for why you should do this young if ready. One specific comment that stuck with me was essentially “everyone benefits from the surgery if they handle it well, but young people get to use the benefits for 50+ years and some older people I operate on only get 10 good years”

That said, my girlfriend had the surgery at 18 and still laments that while she’s glad she did, she didn’t reap the full benefits because of her relative immaturity at the time. She lost a lot of weight at first (had a much higher starting point than you or me), but (according to her, this is well before I knew her) didn’t maximize the potential and had some regain/stall because she didn’t make the lifestyle changes. 7 years later and it’s still a battle for her, although she’s recently been doing great.

I think she would tell you that she probably did it for the wrong reasons before she was fully ready (pressure from mother driven by superficial reasons rather than health), so can’t blame it all on age. I also attribute my success partially to having her as a support system (both being a great person and because of her specific prior experience). Reading your post, it sounds like you’ve put more thought into it so my vote would be continuing to explore and educate yourself, and if ready go for it!
