Repair of a stomach valve during sleeve weight-loss surgery

Medication after weight-loss surgery for type 2 diabetes
This trial looks at whether a specific diabetes medicine given after bariatric (weight-loss) surgery can improve blood sugar control in people with type 2 diabetes. You might be considered if you are eligible for this surgery and meet the weight criteria.
DublinAges 18 years+ - NCT05476627Recruiting
Study risk factors for kidney disease from metabolic conditions
This study looks at risk factors and body “omics” information (like blood/tissue patterns) to better understand chronic kidney disease caused by metabolic diseases. It may help researchers find better ways to predict or manage kidney problems in people with these conditions.
Beijing, Beijing MunicipalityAges 18–80 - NCT04442334Recruiting
European registry for people with fatty liver
This registry collects health and lifestyle information from adults with suspected or confirmed fatty liver (NAFLD) to help researchers better understand the condition. You may be asked about diet, exercise, alcohol intake, and some liver-related tests.

Testing buprenorphine absorption around stomach weight-loss surgery
This study checks how well buprenorphine (a medicine used for opioid dependence and pain in some cases) works in the body after gastric bypass or sleeve gastrectomy. It may help doctors better plan dosing and timing around weight-loss surgery.
TrondheimAges 18–70 - NCT03460379Recruiting
Bariatric surgery and how escitalopram is absorbed
This study looks at how a common antidepressant, escitalopram, moves through your body before and after gastric bypass or sleeve gastrectomy. Results may help doctors better choose dosing for people taking this medication around the time of weight-loss surgery.
TrondheimAges 18–70 - NCT03842475Recruiting
Who may benefit from weight-loss surgery for diabetes?
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.
London, Greater LondonAges 18–80 - NCT05987631Recruiting
Predicting weight loss and health after weight loss 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.
Gouda, South HollandAges 18–75 - NCT04529889Recruiting
Study of gestational diabetes during pregnancy and child outcomes
This study follows pregnant people with gestational diabetes to see how it affects mothers and babies over time. The team may use this information to better understand risks and care for both you and your child.
Guangzhou, GuangdongAges Any age - NCT06061042Recruiting
Time-restricted eating for metabolic health
This study tests whether eating only during a specific time window each day can improve metabolic health in people with obesity and insulin resistance. If you have a high BMI and early signs of diabetes, this trial might help you understand a simple dietary change.
Amsterdam, North HollandAges 50–75 - NCT02208141Recruiting
Child body growth study with planned surgery
This study follows children’s body growth and fat (adipose) tissue as part of a planned surgical procedure. It aims to improve understanding of how fat tissue develops in childhood and what factors may affect health later.
Leipzig, SaxonyAges Any age - NCT03072537Recruiting
Growth monitoring using a doctor-based patient network
This study sets up a network to regularly track children’s growth based on routine doctor or pediatric visits. It may help researchers understand growth patterns and improve how growth is monitored over time.
Leipzig, SaxonyAges Up to 18 years - NCT06039787Recruiting
Exercise and Brain Insulin Sensitivity Study
This study checks if exercise training changes how your brain responds to insulin. You will do ergometer (stationary bike) training, and your brain activity will be measured before and after. It's for people who are not very active now and want to see how exercise affects brain metabolism.
TübingenAges 20–65 - NCT04043520RecruitingPhase 4
Menopause, aging, and energy study
This study looks at how menopause and aging affect the body's energy use. It tests a hormone medication to see how it changes energy levels in healthy women who are recently past menopause.
Aurora, ColoradoAges 40–65 - NCT05801614Recruiting
Tested diet to help control glucose in early type 2 diabetes
This study tests whether carbohydrate or calorie restriction can help normalize blood sugar levels in people with relatively early type 2 diabetes. It may help those whose diabetes control is not yet fully under control but who do not have major recent heart problems.
StockholmAges 24–70 - NCT06192251Recruiting
Lifestyle medicine program for chronic conditions
This trial tests a complete lifestyle medicine program to help people with conditions like prediabetes, diabetes, high blood pressure, heart disease, high cholesterol, or being overweight. The program aims to improve your overall health through diet, exercise, and other lifestyle changes.
Parry Sound, OntarioAges 18 years+ - NCT05798494Recruiting
Pre-pregnancy weight loss plan to protect child weight
This study tests whether a very low-calorie weight loss program before pregnancy can improve the chance that a child will have a healthier weight later. It follows families and stores samples from the child at home.
AarhusAges 18–38 - NCT07870538RecruitingPhase 4
Matching weight-loss treatments to binge eating patterns
This study tests whether a medication called semaglutide, which is used for weight loss, works better for people who also have binge eating. It aims to find the best treatment based on brain and behavior differences.
LeuvenAges 18–65 - NCT07855939Recruiting
Iron absorption and loss in women over time
This study looks at how well women absorb iron and lose it over a long period. It compares normal-weight women with overweight or obese women who have low-level inflammation. The goal is to understand iron levels in the body, which could help improve iron recommendations.
Nakhon PathomAges 40–50 - NCT05315752Recruiting
Body fat changes after CPAP-treated sleep apnea improves
This study looks at how bariatric (weight-loss) surgery may change body fat and body shape in people with severe obstructive sleep apnea who use CPAP. It aims to understand what may improve when sleep apnea is better controlled after surgery.
BrusselsAges 18–99 - NCT04583150Recruiting
Study of fertility and ovarian reserve after weight-loss surgery
This study looks at how ovarian reserve (a fertility-related marker) changes in women after bariatric (weight-loss) surgery versus women with obesity who are not planning surgery. It may help doctors better understand fertility timing and risks around weight-loss treatment.

- How do I know if I qualify for a obese trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a obese trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
