Every person with an eating disorder is unique, and every eating disorder experience is different, brings unique challenges, and responds variously to different treatments. There are increasing calls to 'personalise' treatment to an individual - that is, to offer specific psychological, medical and social support to a person based on their own needs and situation, as well as unique illness features that may predict how they respond to a certain type of treatment. Individualised medicine has been increasingly utilised in other illness groups, however more research is needed into how this approach can be best implemented and adapted for eating disorders across the lifespan.
