You don’t need to know anything apart from what your hoping to achieve. The first consultation is with you pc mine was at Newcastle she was brill went through everything answered any questions, then she can recommend and book you in with a surgon (you can see as many surgons as you want). Then when you meet your surgon he will help you suggest what implants, size, profile ect is best for you and your shape. Depending on what clinic you go to will depend on what hospital I went to Preston Ino there is one in London too I’m not sure we’re the rest are but they will tell you. When I phoned up to book a consultation they got me in the next day. When you book your op day you need to pay a deposit too but it’s up to you when you book your op date xx
