There are several different types of eating disorder. They most commonly begin in adolescence, although they are sometimes experienced by younger children. Other young people, though they may not have eating disorders, may be overweight and concerned about their looks and body image.
Some key facts about eating disorders are set out in 'Growing Through Adolescence' (Health Scotland, 2005) – an evidence-based Continuing Professional Development (CPD) tool for teachers based on a health promoting schools approach to healthy eating:

Most secondary schools will at any given time have at least one pupil who is obviously experiencing an eating disorder. However, many adolescents struggling with negative self-image, dieting preoccupations and cultural pressures may not exhibit easily identifiable signs of the disorder.
Schools that take a holistic approach to awareness-raising about sensitive and difficult subjects will allow space in the school curriculum for supportive education, discussion and communication about these issues. This approach may contribute to preventing eating disorders and may also help those experiencing such disorders to cope with and recover from them.
Detailed information about eating disorders and approaches to prevention, management and treatment is available from a number of sources including those given below.
