“…Potential pre-operative predictors of weight loss in RYGB and VSG include anthropomorphic variables (body mass index (BMI), age, sex, race) [12][13][14][15][16] and behavioral variables, including self-restraint 17,18 , the latter potentially predicting increased dietary adherence after surgery 19,20 . RYGB and VSG reduce sweet taste response and drive for intake mediated by pleasure [21][22][23][24] .…”

Preoperative liking and wanting for sweet beverages as predictors of body weight loss after Roux-en-Y gastric bypass and sleeve gastrectomy

et al. 2019

Background/objectives: Patients who receive Roux-en-Y gastric bypass (RYGB) lose more weight than those who receive vertical sleeve gastrectomy (VSG). RYGB and VSG alter hedonic responses to sweet flavor, but whether baseline differences in hedonic responses modulate weight loss after RYGB or VSG remains untested. Participants/methods: Male and female candidates (n=66) for RYGB or VSG were recruited and tested for their subjective liking and wanting ratings of sucrose solutions and flavored beverages sweetened with aspartame. Participants were classified by unsupervised hierarchical clustering for their liking and wanting ratings of sucrose and aspartame. Participant liking ratings were also used in a supervised classification using pre-established categories of liking ratings (liker, disliker, and inverted u-shape). Effects of categories obtained from unsupervised or supervised classification on body weight loss and their interaction with surgery type were analyzed separately at 3 and 12 months after surgery using linear models corrected for sex and age. Results: RYGB participants lost more body weight compared to VSG participants at 3 and 12 months after surgery (P < 0.001 for both time points). Unsupervised clustering analysis identified clusters corresponding to high and low wanting or liking ratings for sucrose or aspartame. RYGB participants in high-wanting clusters based on sucrose, but not aspartame, lost more weight than VSG at both 3 (P = 0.01) and 12 months (P = 0.03), yielding a significant cluster by surgery interaction.

“… 14 , 15 This might be explained by the fact that only specific personality disorders seem to interfere with weight loss. 26 Moreover, patients in this study had a strict multidisciplinary program before and after surgery, which can be a reason for improved weight loss results. However, the current results might also be explained by the relatively small number of patients and low follow‐up rate in the axis 2 group, with only three patients left after 4 years of follow‐up.…”

Bariatric surgery in patients with psychiatric comorbidity: Significant weight loss and improvement of physical quality of life

et al. 2020

Summary Background Patients that have psychiatric comorbidity are thought to lose less weight than the general bariatric population and are therefore sometimes denied surgery. However, there is no scientific evidence for this assumption. The aim of this study is to evaluate the weight loss and health‐related quality of life (HRQoL) in patients with psychiatric disorders who undergo bariatric surgery and compare these patients with a general bariatric population. Method Patients who underwent bariatric surgery in 2015 were included. Patients who received individual counselling and had a current DSM IV axis 1 or 2 diagnosis were included in the psychiatric group (n = 163), all other patients in the generic group (n = 2362).Weight and HRQoL were assessed before and 12‐, 24‐, 36‐ and 48‐months after surgery. Data was analysed using regression analyses. Results The maximum total weight loss (TWL) was 27.4% in the psychiatric group vs 31.0% in the generic group. Difference in %TWL between the psychiatric and generic group was significant from baseline to all follow‐up moments ( P < .001). Improvement of PHS was significantly higher in the generic group from baseline to 12‐month ( P = .002), 24‐month ( P = .0018), 36‐month ( P = .025) and 48‐monthfollow‐up ( P = .003). Change in mental HRQoL was only different comparing baseline to 48‐monthfollow‐up ( P = .014). Conclusion Although weight loss and change in physical HRQoL was lower in patients with pre‐operative psychiatric disorders, results of this group were still excellent. Thus, patients with psychiatric diagnoses benefit greatly from bariatric surgery and these patients should not be denied weight loss surgery.

“…Two recent systematic reviews have analyzed the relationship between personality traits and bariatric surgery outcomes[ 10 , 11 ]. Better weight loss response is predicted by a combination of different personality traits including high cooperativeness, high persistence, low novelty seeking, low impulsivity, an internal locus of control, a low tendency toward externalizing behaviors, a secure attachment style, and low levels of alexithymia.…”

Emergence of bariatric psychiatry as a new subspecialty

Bariatric surgery is the branch of surgery aimed at helping a person with obesity lose weight. The implementation of surgical treatment of obesity is growing at an impressive rate. As expected, the expanding implementation of bariatric procedures has progressively revealed critical issues that were not evident when the number of obese patients treated with surgery was relatively small. One critical issue is the importance of mental health assessment and care of bariatric patients. The aim of this review is to provide readers with an up-to-date summary of the goals, methods, and clinical strategies of bariatric psychiatry. The aims can be grouped into three distinct categories. First, to ascertain that there are no psychiatric contraindications to safe bariatric surgery. Second, to diagnose and treat pre-surgery mental conditions that could predict poor weight loss. Third, to diagnose and treat post-surgery mental conditions associated with poor quality of life. Although bariatric psychiatry has gained the status of a new subspecialty within the field of mental health and psychopathology, many clinical questions remain unsolved. We need more long-term data on outcome measures such as quality of life, adherence to behavioral guidelines, risk of suicide, and post-surgery prevalence of psychological disturbances and mental disorders.
