Background and Aim: Type 2 diabetes mellitus (T2DM) disparately affects ethnic groups. Prevalence is higher in Asian and Black ethnicities, and these patients suffer increased rates of some diabetes-related complications. Bariatric surgery is an effective treatment for T2DM and can lead to complete diabetes remission. The aim of this study was to assess if T2DM remission rates at 1-year following bariatric surgery vary between different ethnicities.Metho...

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...

Introduction: An excessively long blind-end of the alimentary limb following RYGB, known as a ‘candy cane’ (CC), may cause symptoms such as pain, gastrointestinal symptoms and weight regain. Very few studies have examined the efficacy of surgical resection of the CC. We aimed to assess symptom resolution following CC surgery.Methods: Single centre observational study of 28 CC revisions from 2010 to 2017 (mean age 45±8, female preponderance...

Background: Roux-en-Y Gastric Bypass (RYGB) results in sustained weight loss. Changes in food preferences and eating behaviour are postulated as possible contributing mechanisms. Post-RYGB, patients consume less sugary and fatty food. Sweet taste detection and sensitivity have been reported to be enhanced post-surgery and this may account for changes in the palatability of food. Underlying mechanisms for the changes in sweet taste function and eating behaviour are unclear....

Introduction: Improvement in glycaemia is observed early after Roux-en-Y Gastric Bypass surgery (RYGB) in patients with diabetes. Commonly cited mechanisms to account for these changes include the elevation of gut hormones, increase in bile acids levels, changes in the gut microbiota and calorie restriction. Calorie restriction is believed to play a role in improving hepatic insulin sensitivity and reduce hepatic glucose output early after RYGB, in the context of non-significa...

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...

Bariatric surgery for obesity remains the most effective method to achieve weight loss and improvements in mortality. However, as the number of procedures increases to match the rising burden of obesity, unusual metabolic complications are now coming to the fore. One example of this is postprandial hypoglycaemia (PPH). The incidence of PPH has been reported as <1% although this problem is underreported. A correct diagnosis is essential as the condition can be extremely dis...
