Comparing two types of weight-loss revision surgery after sleeve gastrectomy
This trial compares two surgical options for people who have regained weight or didn't lose enough after a sleeve gastrectomy. It tests whether adding a ring to the standard revision surgery helps with long-term weight loss.
Alexandria, Alexandria GovernorateAges 18–65 - NCT07461610Recruiting
Stool analysis after sleeve gastrectomy vs gastric bypass
This trial compares changes in stool after two common weight-loss surgeries: sleeve gastrectomy and gastric bypass. It aims to understand how these surgeries affect digestion and gut health.

Alcohol and gastric sleeve surgery study
This study looks at how alcohol affects people who have had gastric sleeve surgery (a type of weight loss surgery) compared to those who haven't. It may help explain if surgery changes how your body processes alcohol.

Weight-loss surgery for type 2 diabetes
This study tests whether two weight-loss operations (sleeve gastrectomy or Roux-en-Y gastric bypass) can improve type 2 diabetes. It may help people with higher body weight and diabetes control, but it also requires meeting safety and health criteria.
GothenburgAges 18–60 - NCT02823665RecruitingEarly Phase 1
Compare how bariatric surgery affects blood sugar changes
This early trial studies how blood sugar moves in people after certain weight-loss surgery compared with people without surgery. It may help researchers understand why blood sugar can drop too low and how treatments like atropine affect that process.
San Antonio, TexasAges 18–65 - NCT07600411Recruiting
Weight-loss surgery and mood: comparing two surgical approaches
This study follows patients undergoing one of two common weight-loss surgeries (sleeve gastrectomy or gastric bypass) to see how each affects binge eating, depression, and anxiety. Researchers want to understand which surgery may help improve both weight and mental health outcomes.
Cairo, Al-Manial CairoAges 18–60 - NCT02390973Recruiting
Bariatric-style surgery vs best diabetes care for long remission
This trial compares surgery plus follow-up care versus the best non-surgical (medical) treatment to help people keep type 2 diabetes in remission for a long time. It may be an option if you have higher body weight and diabetes that’s not well controlled, but safety checks are strict.
Québec, QuebecAges 18–60 - NCT07495020Recruiting
Weight loss surgery study for type 2 diabetes
This study tests a new type of weight loss surgery for people with type 2 diabetes and a body mass index (BMI) between 25 and 35. The surgery uses a clip and a special stitch to help with weight loss and diabetes control.

Digestion Study After Weight-Loss Surgery
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.
LeuvenAges 18–65 - NCT06547515Recruiting
Bone and muscle health after sleeve gastrectomy

Endoscopic revision of sleeve gastrectomy for reflux or poor weight loss
This study tests a new, less invasive way to convert a sleeve gastrectomy into a different type of weight-loss surgery (SASI) in people who have ongoing gastroesophageal reflux or haven't lost enough weight. The goal is to see if this endoscopic procedure can improve reflux and help with weight loss without the need for a traditional surgery.
SingaporeAges 21–65 - NCT06934655RecruitingPhase 3
Starting semaglutide again after weight-loss surgery in teens
This trial tests if restarting semaglutide (a weekly injection for weight loss) soon after sleeve gastrectomy helps teens with severe obesity keep losing weight. It is for patients who were already taking semaglutide before their surgery.

Tests satiety changes after bariatric surgery revision
This study looks at how feelings of fullness (satiety) change in people getting bariatric surgery—either a sleeve gastrectomy or a revision procedure. It may help improve how well weight-loss stays on track after surgery.

Check truncal nerve procedure during weight-loss surgery
This study looks at a nerve-related surgical step (“truncal vagotomy”) during revision weight-loss surgery that changes a sleeve stomach to a gastric bypass. It may help improve outcomes for people who need this type of second surgery.
Dallas, TexasAges 18 years+ - NCT07033221Recruiting
Balance and inner ear function in obesity
This study looks at how obesity affects your sense of balance (vestibular function). It compares people with obesity who are candidates for weight-loss surgery to people without obesity, to see if weight affects balance.
Istanbul, KüçükçekmeceAges 18–60 - NCT06271317Recruiting
Complications after sleeve gastrectomy study

Study for weight regain after sleeve stomach surgery
