How does the mind guide the body? Weight gain two years after bariatric surgery, from a psycho-social approach.

Abstract

Introduction: There is no consensus about the cause-effect relationship between psychopathologies and obesity, but it is accepted that the emotional state can interfere with the destructuring of eating patterns and sedentary lifestyle, having an important influence on both body weight.

Objective: To analyze the relationship between psychiatric disorders and weight loss failure, two years after bariatric surgery.

Material and methods: Cohort, retrospective study. Population: 331 patients who underwent bariatric surgery from 2007 to 2016 at the Hospital de la Santa Creu and Sant Pau. Sample: 331 patients. The data was obtained from the query log. Methods of descriptive and inferential statistics were applied, the factorial ANOVA test of repeated measures was specified, forall cases, a statistical significance p <0.05 was considered.

Results: 331 patients were analyzed, of which 95 (28.7%) men and 236 (n = 71.3%) women. The age range ranged from 18 to 65 years. Gastric sleeve is performed in 208 (62.8%) of cases and bypass in 123 (37.2%). The most frequent eating disorder was Glutton (n = 44; 12.4%). The most frequent psychiatric disorder was depression (n = 34; 76.7%). With the student t-test different differences were obtained in the weight loss in the control at the first year and the second year of the surgery (p <0.05). In the repeated measures factorial ANOVA test, a statistically significant relationship between depressive symptoms and weight loss failure was obtained, similarly, between the type of surgery (gastric sleeve) and the weight loss failure.

Conclusion: The history of depressive disorders before surgery and the gastric cuff technique is related to the failure in weight loss in these patients.
