Brief summary
The aim of this observational study is to identify biomarkers in extracellular vesicles associated with medullary adiposity occurring in patients with anorexia nervosa. The main question it aims to answer is: Can this medullary adiposity be associated with the bone deterioration observed in this population? Participants will be assessed for body composition and a blood sample will be taken by non-invasive techniques.
