Background and Aims: Bariatric surgery is the most effective treatment for obesity. however, not all patients have similar weight loss following surgery and many researchers have attributed this to different pre-operative psychological, eating behavior, or quality-of-life factors. the aim of this study was to determine whether there are any differences in these factors between patients electing to have bariatric surgery compared to less invasive nonsurgical weight loss treatments, between patients choosing a particular bariatric surgery procedure, and to identify whether these factors predict weight loss after bariatric surgery.Material and Methods: this was a prospective study of 90 patients undergoing gastric bypass, vertical sleeve gastrectomy, or adjustable gastric banding and 36 patients undergoing pharmacotherapy or lifestyle interventions. all patients completed seven multi-factorial psychological, eating behavior, and quality-of-life questionnaires prior to choosing their weight loss treatment. Questionnaire scores, baseline body mass index, and percent weight loss at 1 year after surgical interventions were recorded.Results and Conclusions: surgical patients were younger, had a higher body mass index, and obesity had a higher impact on their quality of life than on non-surgical patients, but they did not differ in the majority of eating behavior and psychological parameters studied.

“…Además los individuos con malestar sicológico tenían 25 veces más posibilidad de reganar peso 18 . Estas estimaciones son concordantes con los estudios que muestran que pacientes que después de la cirugía bariátrica padecen enfermedades psiquiátricas, tienen alta tasa de reganancia de peso.…”

“…Los trastornos ansiosos motivados por eventos de estrés como duelos, divorcios o pérdida del trabajo, los trastornos de personalidad o enfermedades siquiátricas como la depresión o el alcoholismo, son una causa frecuente de pérdida del control y del autocuidado que experimentan los pacientes que reganan peso. Además del alejamiento de los controles periódicos necesarios con los profesionales encargados del cuidado del paciente con cirugía bariátrica [18][19][20][21][22] . En conclusión, los factores no quirúrgicos, los sicológicos y conductuales son más relevantes que los factores quirúrgicos en la reganancia de peso del paciente con cirugía bariátrica, porque los cambios anatómicos postoperatorios también tienen relación con la conducta alimentaria del paciente y sobretodo porque hay pacientes que mantienen el peso reducido a pesar de tener cambios anatómicos.…”

Weight gain after bariatric surgeryAmong obese subjects, bariatric surgery is very effective to achieve weight loss, to improve metabolic disturbances such as diabetes mellitus and to improve quality of live. However, long term follow up studies show that an important proportion of patients gain weight again. This phenomenon commonly occurs between the third and sixth postoperative year. The main risk factors for weight gain are behavioral and psychological issues, that can be detected in the preoperative assessment. This reinforces the concept that bariatric surgery must be managed by experienced multidisciplinary teams Key words: Obesity, bariatric surgery, weight gain. ResumenLa cirugía para la obesidad ha probado ser el tratamiento más efectivo para reducir el exceso de peso de cualquier magnitud, lo que favorece la mejoría de las comorbilidades metabólicas, especialmente de la diabetes tipo 2 y de la calidad de vida. Los estudios con seguimiento de largo plazo muestran que un porcentaje importante de pacientes operados regana peso, lo que se observa más frecuentemente entre el tercer y sexto año postoperatorio. Existen cambios anatómicos y factores dependientes de la técnica quirúrgica que pueden explicar la reganancia de peso, pero son los aspectos conductuales y sicológicos, los principales factores de riesgo para que un paciente que ha reducido exitosamente su exceso de peso vuelva a engordar. Varios de estos aspectos, son detectables en la etapa preoperatoria, lo que confirma que la cirugía bariátrica debe ser realizada en centros de excelencia que cuenten con equipo multidisciplinario.Palabras clave: Cirugía bariátrica, resultados, reganancia de peso. La cirugía bariátrica ha demostrado ser eficaz para el tratamiento de la obesidad mórbida y las comorbilidades asociadas. Los estudios han demostrado que el tratamiento quirúrgico logra una mayor pérdida de peso que el tratamiento médico para la obesidad de cualquier grado de severidad 1 . Sin embargo, con ningún tipo de cirugía se ha logrado asegurar la mantención del peso en el largo plazo. Reducción del pesoEn los estudios de revisión, se observan cifras de reducción del exceso de peso con un amplio rango. Entre 29 y 87% con banding gástrico (BG), la cirugía más común en el mundo.

Background: Bariatric surgery is the only procedure that has significant results in weight loss and improvements in medical comorbidities in morbid obese patients. Severely obese patients are also associated with a higher prevalence of psychiatric disorders and poor quality of life. Objective: To evaluate specific areas of psychopathology in individuals undergoing bariatric surgery. Methods: A review of the literature was conducted from January 2002 to March 2014 by researching PubMed database using the following query: "morbid AND obesity AND bariatric AND surgery AND (psychiatry OR psychology)". Results: Overall improvements in eating behaviors, mood disorders and body image are reported after bariatric surgery, and the mechanism is not enlightened. Risk of suicide and consumption of substances of abuse, especially alcohol, after gastric bypass surgery are problems that clinicians must be aware. Discussion: Bariatric patients should be monitored after surgery to identify who did not show the expected benefits postoperatively and the ones who develop psychiatric symptoms after an initial positive response.
