Timing of nerve blocks for weight loss surgery pain
This trial tests whether giving a nerve block before or after bariatric surgery works better for pain control. It could help you have less pain and use fewer painkillers after your procedure.
Hamilton, OntarioAges 18 years+ - NCT06720246Recruiting
Weight loss surgery and liraglutide study on thinking and long-term weight
This trial tests whether bariatric surgery or the drug liraglutide helps people with obesity lose weight and keep it off by looking at how it affects your thinking and behavior. It might help you understand which treatment works best for long-term success.
Milan, MilanAges 20–60 - 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 - NCT06696677Recruiting
Measuring small bowel length in repeat weight-loss surgery
This study compares two ways to measure the length of your small intestine during a second weight-loss surgery. One method uses a 3D CT scan before surgery, and the other uses a special tool during surgery. The goal is to see which method is more accurate and safer.
Cairo, Old CairoAges 16–70 - NCT06488183Recruiting
Pain relief study for laparoscopic weight loss surgery
This study compares two ways to manage pain after laparoscopic bariatric surgery: one method involves numbing medicine placed near the surgery site, and the other uses an ultrasound-guided injection near the back. It aims to find which option works better for recovery in people with moderate to severe obesity.
AlexandriaAges 20–50 - NCT07436013Recruiting
Comparing two types of weight-loss revision surgery after sleeve gastrectomy
This trial compares two surgical options for people who have regained weight or didn't lose enough after a sleeve gastrectomy. It tests whether adding a ring to the standard revision surgery helps with long-term weight loss.
Alexandria, Alexandria GovernorateAges 18–65 - NCT06806787Recruiting
Can Copeptin and Thirst Predict Weight-Loss Surgery Success?
This study looks at whether levels of a blood marker called copeptin and your sense of thirst can help predict how well bariatric (weight-loss) surgery works. If you are eligible, you will have blood tests and answer questions about thirst before and after surgery.
Bologna, BolognaAges 18–65 - NCT06757296Recruiting
Endoscopic revision of sleeve gastrectomy for reflux or poor weight loss
This study tests a new, less invasive way to convert a sleeve gastrectomy into a different type of weight-loss surgery (SASI) in people who have ongoing gastroesophageal reflux or haven't lost enough weight. The goal is to see if this endoscopic procedure can improve reflux and help with weight loss without the need for a traditional surgery.
SingaporeAges 21–65 - NCT07336862RecruitingPhase 1/Phase 2
Weight loss surgery plus GLP-1 drug for obesity and diabetes
This trial tests whether adding a GLP-1 receptor agonist (a medication that helps control blood sugar and appetite) after weight loss surgery improves outcomes for people with severe obesity and related health problems like type 2 diabetes.
BeijingAges 18–60 - NCT02902198Recruiting
Study of taste changes before and after bariatric surgery
This study looks at how your sense of taste works before and after bariatric weight-loss surgery. It may help doctors understand why eating patterns change after surgery.
BaselAges 18–55 - NCT07212868RecruitingPhase 1
How glucagon affects blood sugar after weight loss surgery
This study looks at how the hormone glucagon affects blood sugar in people who have had gastric bypass or sleeve gastrectomy surgery more than a year ago, compared to people who have not had any gastrointestinal surgery. It aims to understand glucose metabolism better and may help improve care for people after bariatric surgery.
San Antonio, TexasAges 18–65 - NCT07119437Recruiting
Low-impact laparoscopy for weight loss surgery
This trial compares a newer, less invasive laparoscopic technique to the standard method for sleeve gastrectomy, a type of weight-loss surgery. It aims to see if the low-impact approach reduces pain and speeds recovery.
Rome, ItalyAges 18–65 - NCT06858761Recruiting
Robot-assisted weight loss surgery: cost and results study
This study looks at whether using a robot during weight loss surgery is worth the cost. It compares outcomes for people having their first bariatric surgery or a repeat surgery for complications.
BordeauxAges 18–70 - NCT06829381Recruiting
Personalized one-anastomosis gastric bypass trial
This trial studies a personalized version of a common weight-loss surgery called One Anastomosis Gastric Bypass (OAGB). It aims to see if tailoring the surgery to each person improves results and safety.
Tel AvivAges 18 years+ - NCT06515691Recruiting
Nerve block for pain after weight loss surgery
This study tests a nerve block (an injection near the nerves) to see if it helps reduce pain after laparoscopic sleeve gastrectomy. The block is called a modified thoracoabdominal nerve plane block, and it may lead to better pain control and recovery.
Istanbul, BagcilarAges 18–65 - NCT06425016Recruiting
Robot-assisted vs. traditional sleeve gastrectomy
This study compares two types of weight-loss surgery: one done with the help of a robot and the other done by hand (laparoscopic). Both are types of sleeve gastrectomy, where the stomach is reduced in size. If you qualify for sleeve gastrectomy, this trial may help doctors learn which method works better.
Cleveland, OhioAges 18–70 - NCT05650307Recruiting
Heart and metabolic scan study of weight and rehabilitation
This study uses detailed heart scans and information about metabolism (how your body uses energy) to understand how metabolic treatments and heart rehabilitation may affect your health. You may qualify either as someone undergoing bariatric (weight-loss) care or as part of a heart rehabilitation group—or as a healthy comparison group.
Cleveland, OhioAges 18 years+ - NCT05408728Enrolling by invitation
Check how sugar absorption predicts weight loss after endoscopy
This study looks at whether a person’s “sugar absorption” pattern can help predict how much weight they will lose. It involves an endoscopy (a look inside the upper digestive tract) as part of routine care, and then matching the results to future weight change.
Jacksonville, FloridaAges 18 years+ - NCT04639778Recruiting
