Recruiting studies

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 - 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+ - 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 - NCT05918575Recruiting
Breathing support after a breathing tube in very obese adults
This trial tests whether giving noninvasive breathing support (using a mask or similar device, without a new breathing tube) right after removing a breathing tube works better for severely obese adults. It mainly looks at people at higher risk of needing help breathing again after extubation.
Chicago, IllinoisAges 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 - 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
This study compares how well a specific breathing tube placement tool (Airtraq) works in men who are obese versus men who are not, during planned surgeries. It may help improve the safety and ease of putting in a breathing tube.
IamitAges 18–80 - NCT02811900Recruiting
Study of outcomes after weight-loss (bariatric) surgery
This study follows adults who have bariatric (weight-loss) surgery to see what outcomes they experience afterward. It may help doctors better understand how well the surgery works in real life.
StrasbourgAges 18 years+ - NCT03460314Recruiting
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 - 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 - NCT06264427Recruiting
Study of metabolism issues in Greenland
This study looks at the genes and physical traits of people in Greenland with type 2 diabetes or severe obesity. It aims to better understand these conditions to improve care.
Nuuk, SermersooqAges 18 years+ - NCT07872397Recruiting
Comparing blood sugar control after two weight-loss surgeries
This study compares how well two types of weight-loss surgery control blood sugar levels over time. It may help people with severe obesity understand which surgery could lead to more stable blood sugar after the procedure.
Seville, SevillaAges 18–74 - NCT06226194Recruiting
Genes and weight loss after bariatric surgery
This study looks at how your genes might affect how much weight you lose after gastric sleeve or gastric bypass surgery. You may be able to help doctors better predict weight loss results for future patients.
Lleida, LeidaAges 18–65 - NCT04040413Recruiting
Database update for bariatric weight-loss surgery
This trial is a “database maintenance” study related to bariatric (weight-loss) surgery. It helps keep the records up to date and may support future care by organizing information about patients who get surgery.
Ramat GanAges Any age - NCT07813429Recruiting
Neck posture and pain changes after sleeve gastrectomy
This study looks at how weight-loss surgery (sleeve gastrectomy) may affect the position of your neck, how well your neck moves, and any neck pain you might have. You will be followed for a year to see if losing weight helps improve your neck health.
Istanbul, IstanbulAges 18–65 - NCT07797374Recruiting
Nausea, vomiting, and pain after weight-loss surgery
This study looks at how patients feel after weight-loss surgery, specifically nausea, vomiting, and pain. It uses national registry data to understand these symptoms better, which may help improve care for future patients.
SundsvallAges 18 years+ - NCT07747779Recruiting
Comparing two weight-loss surgeries for very high body weight
This study compares two types of weight-loss surgery to see how they affect hormones after a meal. It may help you choose a surgery that improves your health and weight loss.
Pathum Wan, BangkokAges 18–60 - NCT07565051Recruiting
Predicting weight loss after gastric bypass surgery
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.
Geneva, Canton of GenevaAges Any age - 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.
