I was not in dire need of tummy tuck - it was done during a surgery to repair a hernia. I think my tummy sticks out more now and of course, there is a hip to hip scar.
I went to an outstanding surgeon repeatedly recommended by every doctor friend we know. He was conservative and careful and yet I nearly died several times under anesthesia, it badly damaged my liver - pretty darn serious.
I have a nice tummy but for me, I think I'd have been fine without it.
