Practical approaches to eating disorders in adolescence. Primer for family physicians.

Primary care physicians have an important role in assessing and managing adolescents who present with low weight. Initial diagnosis should be based on current understanding of adolescents' eating behaviours and be followed by obtaining supportive evidence. A practical developmental approach to management should be emphasized. Criteria for hospitalization, a three-step approach to management, and indications for expanding from a primary care to a team approach are discussed.
