mine only needed to take my blood as they couldnt at pre-op (they tried so many times i looked like a druggy), and they only needed blood as i was anaemic when pregnant five years ago. if they hadnt needed my blood, then my docs wouldnt have needed to do anything
others who have had a history of issues, mental health or eating disorders seems most common on here, then they need letters stating your current health, all plans in action as well as all people involved, without that, they assume your a nut job (even though you clearly arent) and the surgeons dont agree with the op. its daft, as girls go through a lot just to book their appointments, they dont need their pasts dragging up xx
haven’t got any history of issues so i should be fine then
