As clinicians in the field of eating disorders, we acknowledge that sometimes calculating treatment target weights can feel out of our scope of practise and this can create a bit of uncertainty for clinicians. In this webinar, we aim to provide more detailed information to help you confidently calculate and communicate treatment target weight ranges to young people, families/carers and wider care team members. As our field has grown, the method for calculating treatment target weight ranges has also evolved, incorporating current research and lived experience perspectives. We have clear guidelines to support clinicians in providing individualised weight ranges for families and young people. In this webinar, we discuss how these target weight ranges can change, and highlight the importance of young people continuing grow and develop throughout childhood, adolescence and into young adulthood.  Key challenges faced by care teams and families will also be reflected on in this webinar from both clinician and lived experience perspectives.
