Trastorno de atracones en pacientes obesos candidatos a cirugía bariátrica

Abstract

Background: Obesity is a chronic disease with a multifactorial etiology. Often it is observed an extensive medical and psychopathological comorbidity. Bariatric surgery is the treatment of choice when the body mass index is greater than 40. It is estimated that 20% of operated patients fail to lose weight and improve comorbidities. Binge Eating Disorder (BED) is one of the main problems of a part of them. The aim of this study was to determine the prevalence of binge eating in obese patients or BED candidates for bariatric surgery and analyze the differences between those with binge eating and no. Methods: 290 obese patients for bariatric surgery with and without binge eating were evaluated regarding demographic, relational variables, clinical, eating behavior, eating psychopathology, general psychopathology, personality traits, quality of life and use of health resources. Results: We observed that patients with binge eating used greater psychopharmacological treatment and show higher levels of eating and general psychopathology. Highlights include obsessivecompulsive traits and limits. Those who have not binge eating have more history of obesity in close family and greater perception of quality of life psychologically. Conclusions: 18.6% are obese with partial or full BED. The clinical characteristics and psychological functioning of partial and complete forms of BED in these obese patients are similar and different from that without binge eatings. The use of health resources has been independent of the presence of BED, except for the number of visits to a psychiatrist.
