(Prof. E. Babicz-Zielińska) trition…, 2003]. Obesity is a chronic non-infectious disease, which signifi cantly deteriorates the quality of life, shortens its length and constitutes a risk factor for many other metabolic diseases such as type 2 diabetes, cancer of uterus, colon and breast cancer, hypertensive disease, degenerative arthritis, stroke and coronary heart disease. The increase in relative body mass index (BMI) by a single unit increases the risk of diabetes by 20-50% and the risk of cancer by 3-10% [Comparative quantifi cation..., 2004].According to estimates by WHO experts in the world more than 1 billion people have an excessive body weight, i.e. more than 300 million are obese and more than 750 million have overweight [World health statistics, 2010]. The overweight affects more men, and obesity more women, therefore women may experience more negative effects of excessive body fat. In Poland, the excessive body weight is observed in 40% to 60% of adults, depending on a survey, including obesity typical of 15% to 20% of adults [Wądołowska, 2009]. The occurrence of excessive weight among children and adolescents does not exceed 15%.The eating disorders seem to be very likely the social problem, even if the data on the extent of the irregularity is fragmented. The eating disorders have morbidity and mortality rates that are among the highest of any mental disorders [Herpertz-Dahlmann et al., 2012]. It is estimated that in the U.S. The eating disorders have been reviewed based on state-of-art of contemporary psychology, medicine and nutrition science, with a special emphasis put on different symptoms and forms, origins and testing methods. Among promoting eating disorders, bulimia nervosa, binge eating disorder, night eating disorder, sleep-related eating disorder are among offi cially approved and investigated. Among disorders resulting from lack of acceptance of own appearance, anorexia nervosa and bigorexia nervosa are the most serious improper ones. Disorders arising from health care include orthorexia nervosa and recently pregorexia. Different origins of eating disorders are considered, divided into three groups: social, psychological and pathological. The desire to possess a slim shapely silhouette and young appearance, usually under pressure of a social group, may result in disorders such as anorexia nervosa, pregorexia, ageorexia, and bigorexia nervosa. On the other hand, the focusing on eating mainly the biologically pure food, being a purely psychological and individual problem, may be a source of orthorexia nervosa. Majority of disorders have a psychological background constituting the escape and an answer to everyday life problems diffi cult to overcome. Recently, pathology is often considered as an additional and important determinant, which may cause or enhance the appearance of binge eating or night eating disorder. The eating disorders, if not subject to proper therapy and advising, can tend to incline and develop. The further research in order to properly recognise the eating disorders,...
