Obesity frequently coexists with psychological disorders such as posttraumatic disorders, depression and various forms of eating disorders. Obese people frequently present low self-esteem in diverse aspects of their life. Irrespective of the fact that the image of cheerful, smiling ‘dumpling’ still persists in society, 80% of people suffering from obesity have diagnosed or hidden depression. Traumatic experiences in childhood (divorce of parents, death of a parent, sexual abuse) frequently result in eating disorders in adulthood. Treatment of obesity without psychological counselling may indicate only symptomatic treatment without discovering a reason of such state.
