I had my gallbladder removed & depending what I wore you wouldn't see the marks. There is one in my belly button, 2 off round the side & one higher up in the middle. None of her bras ever seem to fit so it's possible her bottoms cover any down low & top covers anything higher up. I don't know what kind of incisions they make for weight loss surgery though. I can't really see any reason why she would lie about getting it. I think if she had had more of the "traditional" weight loss journey like alot of the people I see on insta then she would have absolutely turned into a weight loss surgery account. But as her loss has been much slower she hasn't made a big thing of it.
