“…At 12-months post-surgery, none of the patients reported binge eating at the diagnostic threshold frequency specified by the DSM-IV-TR for BED; 8.8% reported infrequent binge eating (i.e., less than once per week) and only one patient (0.7%) reported binge eating weekly. These substantial improvements in binge eating support previous reports of a near remission of binge eating symptoms following surgery 17, 25, 26.…”

Objective This study examined the clinical significance of loss of control over eating (LOC) in bariatric surgery over 24 months of prospective multi-wave follow-ups. Method Three-hundred sixty-one gastric bypass surgery patients completed a battery of assessments before surgery and at 6, 12, and 24 months following surgery. In addition to weight loss and LOC, the assessments targeted eating disorder psychopathology, depression levels, and quality of life. Results Prior to surgery, 61% of patients reported LOC; post-surgery, 31% reported LOC at 6-month follow-up, 36 % reported LOC at 12-month follow-up, and 39% reported LOC at 24-month follow-up. Preoperative LOC did not predict post-operative outcomes. In contrast, mixed models analyses revealed that post-surgery LOC was predictive of weight loss outcomes: patients with LOC post-surgery lost significantly less weight at 12-month (34.6 vs. 37.2% BMI loss) and 24-month (35.8 % vs. 39.1 % BMI loss) post-surgery follow-ups. Similarly, post-surgery LOC significantly predicted eating-disorder psychopathology, depression, and quality of life at 12- and 24-month post-surgery follow-ups. Conclusions Pre-operative LOC does not appear to be a negative prognostic indicator for post-surgical outcomes. Postoperative LOC, however, is a prospective predictor of significantly poorer post-surgical weight and psychosocial outcomes at 12- and 24- month following surgery. Since LOC following bariatric surgery significantly predicts attenuated post-surgical improvements, it represents an important target for clinical attention.

“…This suggestion is consistent with the restraint-theory, which attributes overeating to dieting: attempts to restrict food intake initiate physiological defenses, such as lowering the metabolic rate and persistent hunger, which threaten dieting efforts 24. Like others, we did find a decrease in emotional and external eating,41–43 and that improvements in eating behaviors waned over time 41,43. Also, our findings are partly in line with another study comparing patients’ eating behavior to normative scores; however, as to restrained eating, this study found no significant differences 42…”

Weight loss and eating behavior following vertical banded gastroplasty

BackgroundBariatric surgery is the treatment of choice for patients with morbid obesity. In addition to surgery, postoperative dietary behavior is an important mediator of weight loss and, therefore, critical in influencing outcome. Surgical treatment of obesity is not an alternative to dieting but a method to enforce dieting.MethodsWe evaluated early weight loss and postoperative eating behavior over time. Preoperatively as well as 6 months, 1 and 2 years after vertical banded gastroplasty (VBG), 91 patients were psychologically assessed using a semi-structured interview and a psychological questionnaire focusing on eating behavior.ResultsOver time, we found significant changes in weight, mostly in the 1st postoperative year (EWL= 52.0%); at 2 years, EWL was 61.5%. Patients reported substantial changes in feelings of hunger, appetite, satiety, and eating behavior; however, most improvements waned over time. In addition, there was a wide variability in changes within our patient group, and changes in weight loss appeared to be related to changes in restrained eating.ConclusionVBG not only leads to considerable weight loss, but also to significant improvements in eating behavior, at least within 2 years. However, most improvements wane over time and not all patients profit in the same way.

“…However, various studies provide conflicting results and no clear predictors [94, 95]. Some studies have found poor weight loss postoperatively in the presence of preoperative personality disorders [96], mood disorders [97–99], or eating disorders [100–103]. However, there are also many studies that could not find any relationship between the presence or absence of preoperative psychiatric disturbances and weight loss after surgery [57, 104–108].…”

Psychiatric disorders are not uncommon among severely obese patients who present for bariatric surgery. This paper (1) reviews the results of the published studies using the structured interviews to assess psychopathology in bariatric surgery candidates; (2) compares the prevalence rates of psychiatric disorders across these studies with the data from other population samples; and (3) assesses whether sociodemographic variables appear to affect these prevalence rates. We searched online resources, PubMed, PsychINFO and reference lists of all the relevant articles to provide an overview of evidence so far and highlight some details in the assessment and comparisons of different samples in different countries. The prevalence estimates in the non- treatment obese group did not appear to differ substantially from the general population group in the US or the Italian population samples, although they were relatively higher for the German population. However, the rates of psychopathology in the bariatric surgery candidates were considerably higher than the other two population groups in all the samples. Overall, the most common category of lifetime Axis I disorders in all the studies was affective disorders, with anxiety disorders being the most common category of current Axis I disorders. Certain demographic characteristics are also associated with higher rates of psychopathology, such as, female gender, low socioeconomic status, higher BMI. Overall, methodological and sociodemographic differences make these studies difficult to compare and these differences should be taken into account when interpreting the results.
