Changes in Reward after Gastric Bypass: the Advantages and Disadvantages

Abstract Gastric bypass surgery is an effective long-term weight loss intervention. Key to its success appears a putative shift in food preference away from high-energy-density foods associated with a reduced appetitive drive and loss of neural reactivity in the reward system of the brain towards food. Post-prandial exaggerated satiety gut hormone responses have been implicated as mediators. Whilst the positive impact of bariatric surgery on both physical and psychological outcomes for many patients is clearly evident, a subset of patients appear to be detrimentally affected by this loss of reward from food and by a lack of alternative strategies for regulating affect after surgery. Mindfulness training has emerged as a potential tool in reducing the need for immediate reward that underpins much of eating behaviour. Further research is needed to help identify patients who may be more vulnerable after gastric bypass and which forms of support may be most beneficial.

ConclusionsBariatric surgery could not produce sustainable long ‐term weight loss or comorbidity resolution in PWS. This study suggests that bariatric surgery cannot be recommended to PWS patients as a standard treatment.

One-anastomosis gastric bypass (OAGB), also known as mini gastric bypass, is an increasingly popular bariatric surgery option worldwide. While OAGB offers advantage in terms of procedure time and technical ease, revisional operations to correct complications may be necessary.

AbstractBackgroundPatients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) are under risk of micronutrient deficiencies. We aimed to assess the preoperative and postoperative micronutrient deficiencies in a sample of patients with obesity who underwent LRYGB.MethodsWe evaluated 169 patients —satisfying the National Institute of Health criteria for bariatric surgery—who underwent a LRYGB from January 2014 to July 2017. Before surgery, we recorded a detailed medical history for every patient, and after surgery, we instructed them to return at 1, 6, 12, 24, 36, and 48 months after su rgery.ResultsPre...

Publication date: Available online 7 September 2019Source: Surgery (Oxford)Author(s): William Hawkins, Ian MaheswaranAbstractBariatric surgery is now commonplace in the UK and has been demonstrated to be safe and effective. Complications that present as an emergency are unusual but will be seen more frequently as the number of patients who have undergone weight loss surgery rises. The optimal management encompasses a low threshold of suspicion and early diagnosis of complications, coupled with expertise to deal with them. It is therefore important for a general surgeon to have an understanding of the common bariatric proce...

Abstract OBJECTIVE: There is a need to determine which bariatric operations are the most effective for patients with super obesity and super-super obesity. METHODS: A retrospective cohort study was performed on patients with super obesity and super-super obesity at Mohak Bariatrics and Robotics Surgery Center in Indore, India. RESULTS: Five hundred fourteen patients with super obesity and super-super obesity had surgery at our center from January 2010 through December 2013. The baseline characteristics were different in different operations. The initial average age, weight, and BMI were 44.4 (SD 11....

AbstractObjectiveMost published work on bariatric surgery (BS) in adolescents describes outcomes after laparoscopic adjustable gastric banding (LAGB) or Roux-en-Y gastric bypass. We compared the efficacy of LAGB and laparoscopic sleeve gastrectomy (LSG) in adolescents.MethodsA National Bariatric Registry was queried for adolescents who underwent BS between June 2013 and December 2015. We collected data on weight and height at baseline and 1-year following surgery, subsequent hospitalizations, interventions, and mortality, which were compared at 30  days post-surgery and until last follow-up (maximum 4.2 years pos...

Abstract Bariatric surgery is the most effective treatment for severe obesity and its related comorbidities. Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) are currently the most popular weight-loss surgeries used worldwide. Following these surgeries, many patients self-report changes in taste perception and decreased preference for unhealthy foods. These reported changes might account for increased adherence to healthier diets and successful weight loss after surgeries. However, researchers have used a variety of methodologies to assess patients' reported changes andresults are discrepant. The goal o...
