A breast auto-augmentation generally takes 2 to 4 hours in surgery to complete. This will however all depend on your surgeon and the process of your individual procedure. The procedure will be performed under general anaesthetic and may require an overnight stay at hospital. If staying overnight, you will be taken back to your room to rest and checked on regularly for 24 hours before being discharged by your surgeon. If you are not staying overnight you will still be given time to rest in one of our rooms following surgery and will be checked over by the nursing team.
