Weight-loss surgery plus uterus surgery for certain uterine lining conditions
This trial tests doing weight-loss surgery at the same time as laparoscopic uterus (womb) surgery for people with certain early uterine lining conditions. It may help lower risk from severe obesity while treating the uterine condition.
Boston, MassachusettsAges 18 years+ - NCT04837586Recruiting
Self-weighing at home for teens in weight treatment
This study tests whether having teens weigh themselves at home can help support obesity treatment. It may help families track progress in a structured, supportive way—while screening out teens who have certain eating, mental health, or health factors that could make self-weighing unsafe.
Minneapolis, MinnesotaAges 12–17 - NCT04838678RecruitingEarly Phase 1
Testing a new blood-pressure approach in obesity-related hypertension
This early-stage study tests a new way to help control high blood pressure that is linked to obesity. It may help people whose blood pressure is high based on a 24-hour blood pressure monitor.
Dallas, TexasAges 18–55 - NCT04844684Recruiting
Study hormones and bile acids in women with obesity
This study looks at how cortisol and bile acids are processed in non-menopausal women with obesity. The goal is to understand metabolism differences and potentially guide future treatments or dietary/medication approaches.
LilleAges 18 years+ - NCT04852198Recruiting
Compare two weight-loss surgeries in people with high BMI
This study compares two types of bariatric surgery to see which one works as well as the other for weight loss and health. You may be a candidate if you have a high BMI and specific related health problems, and if certain stomach and digestive issues don’t apply to you.
Almere StadAges 18–65 - NCT04854317Recruiting
Bariatric endoscopy for long-term weight management
This study tests a stomach procedure (endoscopy) to help people with obesity lose weight or control health problems linked to weight. You may be considered if other weight-loss efforts have not worked and surgery is not the best option for you.
OlbiaAges 18–70 - NCT04873258Recruiting
Test a non-invasive tool to screen for fat-related liver disease
This study looks at a new non-invasive screening method to predict metabolic dysfunction–associated steatotic liver disease (MASLD), a condition where fat builds up in the liver. The goal is to help identify people who may be at risk without needing invasive tests.
London, LondonAges 18–80 - NCT04883515Recruiting
Glutamine drink for insulin resistance and bowel symptoms
This trial studies whether taking an oral glutamine supplement can improve insulin resistance and reduce bowel-related problems in people with obesity and irritable bowel syndrome. It may help your blood sugar regulation and digestive comfort if you meet the criteria.
RouenAges 18–65 - NCT04893954Recruiting
Study of spine changes after weight loss from bariatric surgery
This study looks at how rapid weight loss after bariatric surgery may affect your spine over the following year or more. It may help doctors better predict who gets spine-related problems or improvements after surgery.
ParisAges 18 years+ - NCT04934228RecruitingPhase 1
Study targeting inflammation in people with obesity and high blood pressure
This Phase 1 study looks at a treatment aimed at reducing “inflammation patterns” that are common in obesity and insulin resistance. If you meet specific health and lab criteria, you may be asked to visit a research lab and provide blood samples to see how the treatment affects your body.
Kansas City, KansasAges 18–79 - NCT04941651Recruiting

This trial studies whether remote (phone/internet) nutrition coaching helps adults with obesity and/or higher risk for heart and blood vessel problems. It aims to improve weight and related health risks using regular telenutrition support.
ParisAges 18–75 - NCT04942093Recruiting
High-protein low-calorie diet before weight-loss surgery
This trial studies whether a higher-protein, lower-calorie diet before sleeve gastrectomy (a type of weight-loss surgery) changes outcomes after surgery. You may be able to join if you’re scheduled for the operation and meet specific health and safety requirements.
DieppeAges 18–65 - NCT04990024Recruiting
Diet trial for people with obesity using semaglutide
This study compares different diets to see how they affect “arterial stiffness” (how hard the blood vessels are) in people with obesity who are starting semaglutide for weight management. It may help find a diet approach that improves heart and blood-vessel health while you use semaglutide.
Beirut, Riad El SolhAges 18–49 - NCT05028309Recruiting
Study how obesity affects breathing and exercise in older adults
