This document was created based on the need to standardize the psychological examination procedure prior to bariatric surgery. A valuable inspiration was the recommendations issued by the American Society for Metabolic and Bariatric Surgery. Bariatric or metabolic surgery has an undeniable positive effect in the treatment of obesity, in terms of improving somatic diseases, psychological disorders and psychosocial functioning. At the same time, it introduces major changes in the individual's life to which he or she must adapt. The treatment of obesity by surgery requires a fundamental change in lifestyle and the lifelong cooperation of the patient with the entire therapeutic team. Psychological care is a standard part of the entire treatment process. The role of the psychologist is not exclusively diagnostic. In indicated cases, it offers preoperative and postoperative psychological intervention, education and cooperation in the development of an individual treatment plan. Its aim is to deepen the patient's motivation to comply with dietary and regimen recommendations and to provide psychological support in the event of worsening psychological difficulties.
