Eating disorder is a group of disorders characterized by concerns about the shape of your body, body dissatisfaction, focus on body weight control and appearance, and inadequate food intake. Nutrition disorders: anorexia nervosa, bulimia nervosa and compulsive overuse. They mostly occur in younger ages and adolescents. They are characterized by a problematic relationship with food, a negative image of their body and weight, and disrupted self-esteem. At present, great attention is paid to the physical appearance; ie the standards of ideal beauty (perfectionism) and desirable attributes are set. The cause of the disease is responsible for a number of factors, most important of which are biological, psychological and sociological. According to today's psychiatric classification, anorexia and bulimia nervosa and compulsive overeating are classified as eating disorders. The frequent occurrence of illness in young age, the emphasis on society that has a major influence on the illness, the desire for great knowledge and understanding of the specificity of the illness, and the way in which the sufferers want to "hide" the disease and long refuse the help of the family is emphasized. Although different eating disorders manifest differently, everyone is in common that they require professional help and treatment.
