Suboptimal Weight Loss and Weight Regain after Gastric Bypass Surgery—Postoperative Status of Energy Intake, Eating Behavior, Physical Activity, and Psychometrics

Abstract

BackgroundSuboptimal weight loss (SWL) and weight regain (WR) after gastric bypass surgery (GB) remains poorly understood.ObjectivesThis study aims to compare GB patients experiencing SWL or significant WR (SigWR) with successful controls, regarding postoperative food intake, eating behavior, physical activity (PA), and psychometrics.MethodsForty-nine patients with >1 year post-surgery were classified as either experiencing SWL (excess body weight loss, EWL, <50%, n = 22) or SigWR (total weight regain ≥15%, n = 38), with respective control groups. Energy intake (EI) was measured with a Food Frequency Questionnaire, eating behavior using the Dutch Eating Behavior Questionnaire and the Three-Factor Eating Questionnaire, and PA using both SenseWear Armbands and the International Physical Activity Questionnaire. Eating disorders, depression, and quality of life (QoL) were measured using the Eating Disorder Examination Questionnaire, Beck Depression Inventory II, and Impact of Weight on Quality of Life, respectively.ResultsEI, macronutrient distribution, and meal frequency were similar among groups. However, disinhibited eating behavior score was higher, while most subcategories from IWQOL were significantly lower in both SWL and SigWR groups compared with their respective controls. PA was significantly lower in the SWL and SigWR groups compared with the respective controls. There were no differences between groups regarding depression.ConclusionsLower PA levels, disordered eating behavior and lower QoL are associated with unsuccessful weigh loss outcome after GB surgery. Longitudinal studies are needed to clarify the potential causal relationship between the previously described variables and SWL/SigWR after GB.

Weight Change After Roux-en Y Gastric Bypass, Physical Activity and Eating Style: Is There a Relationship?

“…Therefore, bariatric patients are advised to engage in regular physical activity [8][9][10][11]. Previous studies indicate that low physical activity after bariatric surgery is related to less weight loss and more weight regain [12][13][14], though more recent studies question whether weight loss is positively influenced by adherence to a healthy lifestyle with regular physical activity [15,16].…”

“…Emotional eating, in which patients report to eat more in response to emotions, has been linked to less weight loss in two studies [17,18]. However, others did not support this association [12,13]. Studies on self-reported external and restrained eating show the same conflicting results; some suggest a negative effect on weight change, while other studies show no effect [12,13,17,19].…”

Identifying prebariatric subtypes based on temperament traits, emotion dysregulation, and disinhibited eating: A latent profile analysis

“…Notably, both previous cluster models lack the inclusion of emotion dysregulation and disinhibited eating behaviors for subtyping prebariatric patients, although the predictive value of these intrapersonal factors for postbariatric weight outcome was suggested (Amundsen, Strømmen, & Martins, ; Mack et al, ; Marek, Ben‐Porath, Dulmen, Ashton, & Heinberg, ; Wedin et al, ). This study aimed to provide a fine‐grained analysis of prebariatric subtypes by additionally taking emotion dysregulation and disinhibited eating behaviors into account.…”

Desgaste dentário e perdas dentárias em pacientes eutróficos, portadores de obesidade mórbida e submetidos à cirurgia bariátrica

“…É um procedimento cirúrgico comum para pacientes com obesidade mórbida. Os efeitos em longo prazo do BGYR estão bem documentados, tanto em termos de perda de peso, melhoria ou resolução de comorbidades relacionadas à obesidade, como fatores de risco, bem como com a melhoria da qualidade de vida (QV) (Amundsen et al, 2017). Entretanto, a recidiva de peso ocorre em aproximadamente 20% dos pacientes e constitui uma questão preocupante (Meguid et al, 2008).…”
