Introduction: Obesity-associated psychopathological co-morbidities have a negative impact on quality of life. Roux-en-Y gastric bypass surgery (RYGB) has been shown to ameliorate psychological health, however, the underlying mechanisms are not fully understood. Changes in gastrointestinal and central neuroendocrine signalling have been postulated as mediators of psychological and eating behaviour changes following RYGB. Here we assess the impact of subcutaneous infusions of th...

Introduction/Aims: Currently, the most successful long term treatment for obesity is bariatric surgery, however the underlying mechanisms are not fully understood. Changes in gastrointestinal and central neuroendocrine signalling have been postulated as mediators of psychological and eating behaviour changes following bariatric surgery. We aimed to investigate changes in eating behaviour and psychological factors pre- and 1 month post-very low calorie diet (VLCD) and 3-month p...

Background: Bariatric surgery is currently the most effective treatment for weight loss. Its metabolic effects of weight loss and improvement of type 2 diabetes are mediated mainly through the postprandial elevation of gut hormones such as GLP-1, which suppresses food intake and improves insulin secretion.Aim: To characterize the longitudinal changes in fasting and postprandial secretion of glucose, insulin and gut hormones (GLP-1 and GIP) in patients be...

Background: Roux-en-Y gastric bypass (RYGB) leads to effective and sustained weight loss whereas a Very-Low-Calorie diet (VLCD) is normally plagued by weight regain over time. Changes in gut hormones following each intervention may play a role. The aim of this study was to investigate gut hormone responses after 4 weeks of RYGB and VLCD.Methods: We prospectively recruited 21 volunteers with obesity and type 2 diabetes undergoing RYGB, and a matched cohor...
