Is weight loss surgery worth it?

I’ve been struggling with my weight for a while now because of my PCOS and as well as the antidepressants I’ve been taking for the past few years.

I try to maintain a reasonably healthy diet (high fibre, low carb, no dairy) and do 30mins of Pilates x3 a week, but it really doesn’t make much of a difference. My parents have offered to pay for part of the surgery so it’s not a financial issue. But obviously there are a lot of other health related issues to think about so I still torn on whether I should go for it.

Any feedback and advice is welcomed
