The purpose of this study is to assess for elevated levels of calcium oxalate in the urine and kidney stones, in patients who have had gastric bypass surgery for obesity.
Observational studies suggest that bariatric surgery is the most effective intervention for weight loss. Comparative effectiveness of Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) demonstrate that RYGB is significantly superior to SG in terms of weight loss and glycemic control. Both RYGB and SG increase GLP-1 concentrations which directly affect B-cell function. Data has shown that the postprandial rise in GLP-1 might affect feeding behavior after RYGB and to a lesser extent SG, where the increase in GLP-1 is less marked. In this study the investigators propose to randomize subjects undergoing SG to receive either placebo or Liraglutide, a GLP-1 receptor agonist, to compare weight loss and CV risk factors.
The purpose of this study is to assess the acceptability and accuracy of the smart phone food record App ‘HealthWatch 360’ in collecting food intake data from subjects. The nutritional analysis obtained will be compared with that of a 24 hour recall to assess accuracy.
The purpose of this study is to collect and maintain a clinical and pathology database, and a biobank of blood, stool, and tissue specimens, from patients being treated surgically for obesity. The hope is this will ultimately help identify biological predictors for matching the best bariatric surgery to the patient for maximizing the effectiveness of the weight loss.
The purpose of this study is to identify changes to the metabolome (range of chemicals produced in the body) and microbiome (intestine microbe environment) that are unique to Roux-en-Y gastric bypass surgery and assess the associated effect on the metabolism of patients with type 2 diabetes.
It is unknown whether the bile acid pathway reacts differently to weight loss resulting from Roux-En-Y Gastric Bypass (RYGB) surgery than weight loss resulting from caloric restriction alone.
The primary aim is to study the correlation between changes in the gut microbiome of obese subjects undergoing an intragastric balloon procedure.
The purpose of this study is to determine plasma levels of Peptide YY (PYY), ghrelin, ammonia, and amino acids prior to and after Roux-en-Y gastric bypass surgery.
