Eating disorders are serious mental health conditions which can adversely affect the person’s physical health and disrupt their psychosocial functioning. It has been established that social media use can increase the risk of disordered eating behaviours, but there is little research into the role of social media in recovery from eating disorders. This systematic review aimed to identify and synthesise the qualitative data on the use of social media during the recovery phase of an eating disorder. Conflicting themes emerged, with data showing that social media can be a useful tool in the recovery phase, for example by enabling people to connect with others, but have detrimental aspects, in particular the ongoing availability and promotion of content that can put recovery at risk. Nurses should include social media use in their holistic assessments of service users and work with them to empower them to make decisions about their use of social media during illness and recovery.
