Recruiting studies
- NCT02904291Recruiting
Blood-pressure medicine study around weight-loss surgery
This study checks how amlodipine (a blood-pressure medicine) gets absorbed in your body before and after gastric bypass or sleeve gastrectomy. It may help doctors better manage blood pressure medicines after weight-loss surgery.
TrondheimAges 18–70 - 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+ - NCT02937649Recruiting
Testing a bougie tool during sleeve stomach surgery
This trial checks a specific surgical measuring tool (“bougie”) used during sleeve gastrectomy (weight-loss stomach surgery). It may help the surgical team improve how the sleeve is formed while keeping safety in mind.
Boulogne-BillancourtAges 18–70 - NCT02939664Enrolling by invitation
Laparoscopic gastric bypass vs banding for weight loss
This trial compares two types of minimally invasive weight-loss surgery: gastric bypass versus a gastric band. It looks at which approach works better and is safer for people who qualify for bariatric surgery and have not succeeded with supervised weight-loss programs.
Majadahonda, MadridAges 18–65 - NCT01055054Enrolling by invitation
Bariatric surgery registry for people with severe weight gain
This study is a registry, meaning it collects health information to better understand outcomes after bariatric (weight-loss) surgery. It may help doctors improve care for people with severe obesity who had surgery at VCU Medical Center.
Richmond, VirginiaAges 12–75 - NCT07446972Recruiting
Bariatric surgery and female sexual health study
This study looks at how weight-loss surgery (bariatric surgery) affects a woman's sexual function and hormone levels. It follows women who are already scheduled for surgery to see if their sexual health changes after the procedure.
Cairo, Al-Manial CairoAges 18–45 - 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.
Cairo, Al-Manial CairoAges 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 - NCT06581120Enrolling by invitation
Stomach ultrasound study for diabetes and obesity
This study uses ultrasound to see how GLP-1 RA medications (like Ozempic) affect the stomach in people with type 2 diabetes and obesity. It may help doctors better understand how these medicines work.
Cincinnati, OhioAges 10–25 - NCT04841057Enrolling by invitation
Study of blood and stool changes after weight-loss surgery
This study looks at how your body’s metabolism changes after a specific weight-loss surgery (gastric bypass). It may help researchers better understand what to expect and how to tailor care, while requiring blood draws and stool samples before and after surgery.
Columbia, MissouriAges 18–80 - NCT03692455Enrolling by invitation
Compare two weight-loss surgeries for reflux over 8 years
This study follows people for up to 8 years to see how two different weight-loss surgeries affect ongoing heartburn and acid reflux. You would join only if you were already enrolled in an earlier related study and can complete required follow-up visits and tests.
Passo Fundo, Rio Grande do SulAges 18–78 - NCT05802121RecruitingEarly Phase 1
Testing a gut bacteria supplement side effects during prostate hormone therapy
This early-phase study looks at how changing gut bacteria (especially Akkermansia) affects metabolic side effects in men starting prostate hormone therapy (ADT). It may help researchers understand how to reduce or manage side effects for people on ADT.
