Weight Loss Preparation Before Gastric Bypass Surgery
Part of Heart & circulation, Hormones & metabolism clinical trials.
This study compares three different approaches to help you lose weight before a specific type of gastric bypass surgery. You'll be randomly assigned to receive either a new medication (tirzepatide), follow a special high-fat diet, or receive standard care before your surgery.
Summary written for real people, not researchers, by Clin2.

This study looks at how gut hormones and blood sugar control change after Roux-en-Y gastric bypass. It may help researchers understand what supports healthier glucose levels after bariatric surgery.
This study looks at which people with type 2 diabetes (or prediabetes) are most likely to benefit from bariatric surgery. It compares people who are planning surgery with healthy volunteers to better understand how body changes relate to blood sugar.
This study tests whether bariatric (weight-loss) surgery can improve blood sugar control in people with obesity and either prediabetes or type 2 diabetes. You may be enrolled in one of these glucose groups, and the researchers will monitor changes before and after surgery.
This study looks at why some people lose more weight and improve their health more than others after bariatric surgery. It also has a subgroup that specifically studies people who are insulin resistant (a sign of prediabetes) to see how surgery affects their metabolism.
This study compares two kinds of weight-loss surgeries to see which helps people with type 2 diabetes reach diabetes remission more safely. It may help if your diabetes is not well controlled and your care team recommends one of these operations.
This study looks at whether measuring muscle mass before gastric bypass surgery can predict how much weight you'll lose afterward. Understanding this connection may help doctors better prepare patients for surgery and set realistic goals.
