Carer burden amongst carers of youth with an eating disorder is substantial and if not addressed can lead to negative outcomes for the patient, carer and family. The Coronavirus Disease 2019 (COVID-19) pandemic has made caring for youth with an ED even more onerous and preliminary research is beginning to emerge demonstrating the profound negative impact the pandemic is having upon individuals with EDs and their carers. MAIN: In this review, we briefly summarize what is known about carer burden in families where a young person has an ED, consider the additional impact consequent to COVID-19 and highlight the need for interventions aimed at alleviating this. Pre-COVID-19 research identifies high levels of psychological and physical strain amongst those caring for a child with an ED. Themes are beginning to emerge as to why COVID-19 may further exacerbate carer burden: (1) reduced access to ED services; (2) increased physical vulnerability and exacerbation of psychiatric co-morbidity amongst youth with EDs; (3) increased practical demands placed on carers; and (4) social isolation and decreased social support.
