Study for weight regain after sleeve stomach surgery
This trial studies a specific type of metabolic (weight-related) surgery for people whose sleeve gastrectomy did not lead to enough weight loss or has caused significant weight regain. It may help improve long-term weight and related health problems.

This trial compares a special stent (the Luso-Cor Stent) to other endoscopic procedures to treat leaks or abnormal connections after certain stomach or esophageal surgeries. It aims to find the best way to fix these complications using a scope.
Lisbon, Lisbon DistrictAges 18 years+ - NCT05918575Recruiting
Breathing support after a breathing tube in very obese adults

Study on nutrition and mouth health risks after obesity treatment
This trial looks at risks like malnutrition, weak bones, and oral (mouth) health problems after obesity treatment. It may help improve follow-up care for people who receive specialist treatment or weight-loss surgery.
GothenburgAges 18 years+ - NCT05554016Recruiting
Ultra-processed food study in kids with obesity
This study looks at how eating ultra-processed foods affects metabolism and body weight in children and teens with obesity, and compares them with healthy peers. Your participation may help scientists understand whether diet choices contribute to weight and metabolic problems.
NaplesAges 6–18 - NCT06341699Recruiting
Hormones in severe obesity
This study looks at hormone levels in people with severe obesity to understand how they differ from others. It may help explain how obesity affects the body.
Oggebbio, VerbaniaAges 18–80 - NCT06499597Recruiting
Duke Activity Score in People with Obesity
This study tests a simple questionnaire (the Duke Activity Status Index) to see how well it measures daily physical activity in people with obesity. If you have a BMI over 30 and are generally healthy, joining could help doctors find better ways to assess your fitness.
SanliurfaAges 18–65 - NCT06620562RecruitingPhase 4
Testing a weight loss pill after sleeve gastrectomy surgery
This study tests whether adding a medication (naltrexone/bupropion) to sleeve gastrectomy surgery can improve weight loss. It may be a good fit if you are eligible for a first-time sleeve gastrectomy and meet certain health criteria.
Québec, QuebecAges 18–65 - NCT06916364Enrolling by invitation
Airway rod for intubation in adults with obesity
This trial tests if a special rod helps place a breathing tube more easily in adults with obesity who are having planned surgery. It could make the procedure safer and more comfortable.
Houston, TexasAges 18 years+ - NCT05917795Recruiting
Endoscopic stomach reduction for weight loss before kidney transplant
This trial tests an endoscopic procedure that helps reduce stomach size to support weight loss in people with severe kidney disease who may need a kidney transplant. It may help some patients meet transplant-center weight requirements and potentially improve readiness for transplant care.
RomeAges 18–70 - NCT05554224Recruiting
Personalized treatment based on obesity-related fatty liver tests
This study uses multiple types of health data (“multi-omics”) to help choose a personalized treatment plan for people with obesity-related fatty liver disease. It may help match treatment to your biology to improve outcomes.
Reus, TarragonaAges 18 years+ - NCT05215886Enrolling by invitation
Bariatric surgery and memory problems in people with obesity
This study looks at how bariatric (weight-loss) surgery may affect memory and thinking in people with obesity who already have memory decline or dementia. It may help doctors understand which patients benefit most and what changes to expect.
Sacramento, CaliforniaAges 18–75 - NCT04643262Enrolling by invitation
Looking back at bariatric surgery outcomes in obesity
This study looks back at people who had sleeve gastrectomy (a weight-loss operation) and compares results and complications. It may be a fit if you match the study’s age, weight, and health history, though it’s a “retrospective” review, so it mainly uses past records.
Ages 18–68 - NCT05120492Recruiting
Program for severe knee arthritis and extreme weight
This feasibility study tests a practical approach to help people with very severe knee arthritis and very high body weight. It aims to find an effective and safe way to manage both conditions together in real-world care.
Halifax, Nova ScotiaAges 18–65 - NCT05974995Recruiting
Robotic or standard surgery for early uterine cancer in obesity
This trial compares robotic-assisted surgery versus standard laparoscopic surgery for people with early-stage uterine (endometrial) cancer and a BMI of 30 or higher. The goal is to see which approach is safer and works better for this group.
RomeAges 18–75 - NCT05927519Recruiting
Compare a laryngoscope tool in obese vs nonobese men
