Abstract

INTRODUCTION: Morbid obesity has multiple implications for psychological and physical health. Bariatric surgery has been selected as the treatment of choice for this chronic disease, despite the controversial impact of the surgery on psychosocial health. The objective of this study was to describe candidates for bariatric surgery and analyze changes in weight, psychopathology, personality, and health problems and complaints at 6- and 12- month follow-up assessments. METHODS: Thirty obese patients (20 women and 10 men) with a mean age of 39.17±8.81 years were evaluated in different dimensions before surgery and 6 and 12 months after the procedure. RESULTS: Six and 12 months after bariatric surgery, patients reported significant weight loss and a significant reduction in the number of health problems and complaints. The rates of self-reported psychopathology were low before surgery, and there were no statistically significant changes over time. The conscientiousness, extraversion, and agreeableness dimensions increased, but neuroticism and openness remained unchanged. All changes had a medium effect size. CONCLUSIONS: Our results suggest that patients experience significant health improvements and some positive personality changes after bariatric surgery. Even though these findings underscore the role of bariatric surgery as a relevant treatment for morbid obesity, more in-depth longitudinal studies are needed to elucidate the evolution of patients after the procedure.

Resumo

INTRODUÇÃO: A obesidade mórbida tem várias implicações para a saúde psicológica e física. A cirurgia bariátrica tem sido o tratamento de escolha para essa doença crônica, apesar da controvérsia sobre o impacto da cirurgia na saúde psicossocial. O objetivo deste estudo foi descrever candidatos a cirurgia bariátrica e analisar mudanças no peso, psicopatologia personalidade, problemas e queixas de saúde desses pacientes em avaliações realizadas 6 e 12 meses após a cirurgia. MÉTODOS: Trinta pacientes obesos (20 mulheres e 10 homens) com idade média de 39,17±8,81 anos foram avaliados em diferentes dimensões antes da cirurgia e 6 e 12 meses após. RESULTADOS: Aos 6 e 12 meses após a cirurgia bariátrica, os pacientes relataram significativa perda de peso e significativa redução no número de problemas e queixas de saúde. As taxas de psicopatologia autorrelatada foram baixas antes da cirurgia e não sofreram mudanças significativas com o tempo. As dimensões conscienciosidade, extroversão e agradabilidade aumentaram, mas o neuroticismo e a abertura permaneceram inalteradas. Todas as mudanças apresentaram um tamanho de efeito médio. CONCLUSÕES: Os nossos resultados sugerem que os pacientes experimentam melhoras significativas em saúde e algumas mudanças positivas de personalidade após a cirurgia bariátrica. Embora esses achados reforcem o papel da cirurgia bariátrica como um tratamento relevante para a obesidade mórbida, mais estudos longitudinais e aprofundados são necessários para elucidar a evolução dos pacientes após a realização do procedimento.
