Sims with eating disorders or body image disorders can have different emotions based on the surgery which can change the longer they live with it. Surgery can be successful and Sims are generally pleased with the results of successful surgery whereas if the surgery is unsuccessful Sims can experience embarrassment. To bypass this, you can download the TwistedMexi mods in #4 of the instructions. Very Important: Before sending your sim to surgery, make sure testing cheats are enabled and that you have used the cas.fulleditmode cheat else you will not be able to edit your sims face or body. Sims have three days to do the surgery after which they lose their appointment. If the consultation is unsuccessful the Sim will not want to follow through with the procedure. If the consultation is successful, the Sim will want to go through with the surgery and will need to choose their cosmetic surgeon (cheap, expensive, celebrity).
The sim will go to a clinic for their consultation. Any sim teen and older can sign up for a Cosmetic Surgery Consultation, available on the phone under my phone menu.
