Recruiting studies
- NCT06275061Recruiting
Obesity and metabolic surgery database study
This trial is building a database of people with obesity who have had or are planning to have weight loss surgery (metabolic or bariatric surgery). It helps doctors learn more about long-term results and safety.
Guangzhou, GuangdongAges Any age - NCT06600555Recruiting
Metabolic surgery for diabetes control
This trial tests a type of weight-loss surgery (called metabolic surgery) to see if it helps people with type 2 diabetes achieve better blood sugar control. It's for people who have struggled to manage their diabetes with standard treatments and have a BMI between 30 and 35.
VilleurbanneAges 18–65 - NCT06756789Recruiting

This study compares two different ways of measuring the length of the small intestine during a type of weight loss surgery called gastric bypass. If you are eligible, you may help determine which approach leads to better weight loss results.
Coimbatore, Tamil NaduAges 18–65 - NCT03520699Recruiting
Metabolic surgery registry for sleeve or bypass patients
This registry collects information from people who plan to have metabolic surgery, such as sleeve gastrectomy or gastric bypass. It may help doctors learn which approaches work best and improve care over time.
BeijingAges Any age - NCT06374875RecruitingPhase 4
Does metabolic surgery reduce liver scarring?
This study tests if weight loss surgery can improve liver fibrosis (scarring) in people with obesity and advanced liver disease. It may help those considering surgery to know if their liver health can get better.
Phoenix, ArizonaAges 18–75 - NCT07163650RecruitingPhase 4
Obesity medication 6 months after weight-loss surgery
This trial is for people who had metabolic surgery 6 months ago and still have a BMI of 28 or higher. It tests whether an anti-obesity medication can help with further weight loss after surgery.
Nanjing, JiangsuAges 18–55 - NCT03800160Enrolling by invitation
Metabolic and bariatric surgery registry in Greater China
This is a registry that collects information from people who are having weight- and metabolism-related surgery. Your data may help doctors and researchers understand outcomes and improve care in the region.
Beijing, Beijing MunicipalityAges Any age - NCT06059651Recruiting
Bariatric Surgery and its Effects on Fat, Immune Cells, and Cancer
This study looks at how bariatric (weight-loss) surgery affects fat metabolism, immune cells, and cancer risk in women with severe obesity and high cholesterol. If you are a woman aged 35–60, White or Black, with a BMI of 40 or higher and high triglycerides or LDL, you may be eligible.
Baton Rouge, LouisianaAges 35–60 - NCT06107959Recruiting
Metabolism changes after bone or joint surgery
This study measures how your metabolism (how fast your body burns energy) changes after orthopedic surgery (surgery on bones or joints). It may help doctors understand how to better support recovery.
Kansas City, KansasAges 15 years+ - NCT03467581Recruiting
Five-year follow-up after laparoscopic stomach sleeve surgery
This study looks at how people do over the next five years after getting laparoscopic (keyhole) gastric sleeve surgery for obesity. It may help doctors understand long-term outcomes and benefits for future patients.
TartuAges 18–65 - NCT05000996Recruiting
Gut microbiome study for people having metabolic surgery
This study looks at your gut bacteria (your “microbiome”) around the time of metabolic surgery. It may help researchers understand how surgery affects gut health and related conditions like diabetes, blood pressure, and cholesterol.
Nashville, TennesseeAges 21–65 - NCT05363059Recruiting
Bariatric surgery compared with standard treatment for metabolic syndrome
This trial compares bariatric (weight-loss) surgery with medical (non-surgery) treatment in people with metabolic syndrome, a cluster of risk factors that can affect heart and blood sugar. It aims to see which approach improves these health risks and overall metabolism.
Chongqing, Chongqing MunicipalityAges 18–65 - NCT05859022Recruiting
Bariatric treatment methods compared for diabetes and metabolism
This trial compares a less invasive heart/artery-based bariatric treatment (bariatric arterial embolization) with standard weight-loss surgery to see how they affect metabolism and type 2 diabetes. You might be considered if you have obesity with type 2 diabetes and have not had prior bariatric surgery.
LisbonAges 18–75 - NCT02823665RecruitingEarly Phase 1
Compare how bariatric surgery affects blood sugar changes
This early trial studies how blood sugar moves in people after certain weight-loss surgery compared with people without surgery. It may help researchers understand why blood sugar can drop too low and how treatments like atropine affect that process.
San Antonio, TexasAges 18–65 - NCT07156552Recruiting
Protein and exercise to prevent muscle loss after weight loss surgery
This trial tests whether taking extra protein and doing resistance training helps people keep their muscle mass after bariatric surgery (stomach reduction or gastric bypass). If you're scheduled for this surgery and can follow the program, you may be able to join.
AmsterdamAges 18 years+ - NCT07093502Recruiting
Predicting outcomes after weight-loss surgery for severe obesity
This study is creating a system to predict how well people do after weight-loss surgery for severe obesity. It focuses on patients getting either a sleeve gastrectomy or a gastric bypass and aims to improve recovery and long-term results.
Changsha, HunanAges 18–50 - NCT07335731Recruiting
Safety and effectiveness of a new robot for weight-loss surgery
This trial tests a new robot-assisted device for weight-loss surgery in people with obesity. It aims to see if the device is safe and works well for metabolic conditions.
BeijingAges 18–65 - NCT06868992Recruiting
Study of MASH and cell changes in weight-loss surgery
This study looks at a possible link between MASH (liver inflammation with fat buildup) and tiny cell structures that help liver cells work. Researchers want to understand this better in people having weight-loss surgery, where a small liver sample will be taken.
Lyon, FranceAges 18–99 - NCT06538948Recruiting
Eating behavior after weight loss surgery
This study measures how people eat and how their gut hormones change after weight loss surgery. It compares different groups to understand differences between men and women.
Männedorf, Canton of ZurichAges 18 years+ - NCT06914219Recruiting

This study tests a program to screen for and treat eating disorders in people who have had weight loss surgery. It aims to find and help those struggling with eating issues after surgery.
Halifax, Nova ScotiaAges 19 years+ - NCT04634591Recruiting
Weight-loss surgery study for people with severe obesity
This trial studies bariatric (weight-loss) surgery and how well it helps people reach and keep a healthier weight. You may qualify if you have severe obesity and have not been able to maintain weight loss with other attempts, and if you can safely follow the study plan.
Bialystok, Podlaskie VoivodeshipAges 18 years+ - NCT04284943Recruiting
Surgery for stomach cancer and diabetes
This trial tests a surgery for early-stage stomach cancer that also aims to improve type 2 diabetes by changing how your body processes food. It might be an option if you have both conditions and are not using insulin.

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.
Québec, QuebecAges 18–60 - NCT07058155RecruitingPhase 4
TIPS and weight-loss surgery for liver disease with high blood pressure
This trial tests if doing a TIPS procedure (to lower blood pressure in the liver) before weight-loss surgery (sleeve gastrectomy) helps people with advanced liver disease. It's for those who have cirrhosis and very high blood pressure in the liver, and who qualify for sleeve gastrectomy.

Common questions
- Are there clinical trials for metabolic surgery?
- Yes. Clin2 currently lists 66 recruiting metabolic surgery studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a metabolic surgery 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 metabolic surgery 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.
