The effects of bariatric surgery are not only physical but also psychological, according to research from the National University of Distance Education (Universidad Nacional de Educación a Distancia), Madrid, Spain, which analysed the psychological consequences of surgery.

Dr Alejandro Magallares, a researcher at UNED, and co-author of the study, reviewed 21 scientific articles regarding the relationship between quality of life and weight (gauged with the questionnaire SF-36, which sheds light on the state of health of the person) in the obese population before (2,680 subjects) and after (2,251 subjects) undergoing this surgery.

The results reveal that obese patients scored less in the mental health component of the Short-Form 36 before bariatric surgery than after. The same pattern was observed in the case of the physical health component of the Short-Form 36. The results show the strong improvement that obese patients experience in both mental and physical components of the Short-Form 36 after receiving bariatric surgery

"An increase was found in the quality of life related to both psychological and physical aspects after the surgical intervention," said Magallares, who published a paper ‘Mental and physical health-related quality of life in obese patients before and after bariatric surgery: A meta-analysis.’ in the journal Psychology, Health & Medicine. "Both physical and psychological health improve after the operation, and that increase in quality of life is especially significant in the physical area."
