Variation of Binge Eating One Year after Roux-en-Y Gastric Bypass and Its Relationship with Excess Weight Loss

Abstract

BackgroundBariatric surgery is the most effective treatment for obesity classes II and III. However, some patients do not get the desired results or initially lose and then regain the lost weight. Identifying these individuals early on and treating them adequately remains a challenge. As binge eating directly affects food intake, the study of this symptom and its relation to bariatric surgery and its results is increasing, because it appears to have an influence on the results of surgery.ObjectivesThis study aimed to see how binge eating changes, measured with the Binge Eating Scale, interferes in the % excess weight loss one year after Roux-en-Y gastric bypass.MethodsWe conducted a cross-sectional study with 149 patients older than 18 years who were evaluated one year after undergoing Roux-en-Y gastric bypass. The variation in the intensity of binge eating was measured with the pre- and postoperative Binge Eating Scale scores.ResultsThe variation of one unit in the Binge Eating Scale implied an inverse variation of 0.41% of % excess weight loss (p<0.05). The correlation coefficient between the variation of binge eating and the % excess weight loss was -0.186 (p = 0.033). The correlation coefficient between the binge eating symptoms one year after surgery and the % excess weight loss was -0.353 (p<0.001).ConclusionsThere was a correlation between the variation of binge eating one year after gastric bypass and the % excess weight loss. The correlation between binge eating and the % excess weight loss was greater after the surgery than it was at the preoperative stage. This study provides new, valuable information on the intensity and variation of binge eating symptoms one year after gastric bypass, which, to the best of our knowledge, have not been studied in depth earlier.

Psychological outcomes following surgical and endoscopic bariatric procedures: A systematic review

“…There were seven studies that measured binge eating outcomes at 12 months post‐surgery. Five out of these seven studies reported a reduction in binge eating symptoms from pre‐surgery, but two studies did not report whether changes were statistically significant . One study used a clinical assessment and found that pre‐surgery BED reduced from 100% to 8%; however, this study did not indicate whether this was a statistically significant reduction .…”

“…Binge eating is highly prevalent among bariatric surgery candidates and has been shown to range from 6% to 35%, with some studies reporting prevalence rates as high as 50% . Binge eating symptoms have been associated with weight regain, reduced weight loss, higher body mass index (BMI), poorer mental health, and persistent eating difficulties following bariatric surgery . The impact of binge eating on psychological and medical difficulties pre‐surgery and post‐surgery is noteworthy and highlights the need for further investigating this behaviour among bariatric surgery patients.…”

“…Six studies conducted RYGB or GBY, three used LAGB, one used SG, and one study used BPD . Only one study examined the differences between procedures .…”

Eating Behaviour Predicts Weight Loss Six Months after Bariatric Surgery: A Longitudinal Study

“…Adherence to the dietary recommendations provided was shown to be an important predictor of successful weight loss outcome [ 18 ]. Presence of disordered eating behaviours, such as grazing [ 18 ] and bingeing [ 19 ], were associated poorer weight loss outcomes. Interestingly, among those who had low adherence to recommended dietary regiments, those who grazed not more than once per day had a weight loss success rate of 68.3%, as compared to 27.6% among those who grazed more than once [ 18 ].…”

The influence of total bowel length on gastric bypass outcomes

“…An RYGBP may fail when it's primary outcome is not achieved, whether this is resultant from either an insufficient weight loss from what is predicted [13][14][15] or the patient regains weight shortly after the procedure is performed.…”
