The paper describes eating disorders, preventive measures as well as preventive programs and the role of family and nurses in the prevention of eating disorders. Eating disorders are a serious problem that is increasingly widespread among the younger population. The disorder itself not only affects the eating pattern, but also has a great impact on the individual's mental health. Eating disorders are one of the leading public health problems worldwide today. Everywhere in the world, including in Croatia, the influence of the media on the unrealistic ideals of beauty that young people persistently try to achieve is increasing. From this came the preventive programs that are mentioned in the work, and for many years they have been helping young people in the prevention of eating disorders. In addition to preventive programs, there is also the role of parents and medical professionals in educating young people about the prevention of the disorder itself. The aim of the work was to show the seriousness of eating disorders and how they can be prevented even in the youngest age groups. In addition to the presentation of prevention and description of the disorders themselves, the goal is to show the importance of participation and support for people who suffer from or are at risk of developing eating disorders.
