Study changes in the body after weight, gut, or liver treatment
Part of Digestive system, Hormones & metabolism clinical trials.
This study looks at how the body’s insulin-sensitivity (how well your body uses sugar/insulin) and organ function change after certain medical procedures. It may help researchers understand why some people improve after surgery or liver transplant and guide future care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for an upper endoscopy, colonoscopy, metabolic/bariatric surgery, or a liver transplant at Vanderbilt
- If you’re having metabolic or bariatric surgery: you have obesity (BMI at least 40, or 35 with a health problem such as type 2 diabetes, fatty liver, high blood pressure, heart disease, or high cholesterol)
- If you’re having a liver transplant: you have nonalcoholic liver disease or nonalcoholic steatohepatitis (fatty liver related to metabolism)
- You do not have inflammatory bowel disease (Crohn’s or ulcerative colitis) or celiac disease
- You do not smoke more than 7 cigarettes per day and you are not pregnant or breastfeeding

Other trials that look related to this one.
This study looks at your gut bacteria (your “microbiome”) around the time of metabolic surgery. It may help researchers understand how surgery affects gut health and related conditions like diabetes, blood pressure, and cholesterol.
This study looks at how fat build-up in the liver relates to metabolism in people who are scheduled for weight-loss (bariatric) surgery. By doing special blood tests and MRI scans, researchers hope to better understand liver health and improve care.
This study collects small tissue samples during planned weight-loss surgery to better understand metabolism and how insulin works in people with and without type 2 diabetes. You may help researchers by allowing their team to take these samples while you are already having surgery.
This study collects small tissue samples during certain abdominal surgeries to better understand what drives severe obesity and related blood-sugar patterns. If you agree to the extra sampling, your information and samples may help researchers build a “biological atlas” that could guide future treatments.
This study tests whether weight-loss surgery improves how your body uses insulin and energy. It compares insulin sensitivity and related measurements before and after surgery to understand who benefits.
This study looks at how digestion works after weight-loss surgery. Volunteers may be people with obesity or those who had gastric bypass or sleeve gastrectomy at least a year ago. The goal is to learn more about gut function after surgery.
