Recruiting studies
- NCT05305313RecruitingPhase 4

Study for people who don’t lose weight after bariatric surgery

LondonAges 18–70 - NCT05777928Recruiting
Tests satiety changes after bariatric surgery revision
This study looks at how feelings of fullness (satiety) change in people getting bariatric surgery—either a sleeve gastrectomy or a revision procedure. It may help improve how well weight-loss stays on track after surgery.

Testing how dairy affects heart risk in people with high weight
This study looks at whether eating more dairy (from cow’s milk) changes markers linked to heart and metabolic risk in adults with higher body weight. It mainly aims to understand how diet affects the body’s metabolism and related risk factors.
Pierre-BéniteAges 18–70 - NCT05816798RecruitingPhase 2/Phase 3
Laser treatment to reduce chronic knee pain before weight-surgery
This trial tests whether photobiomodulation (a type of laser/light therapy) can reduce chronic pain in both knees for people preparing for bariatric (weight-loss) surgery. If you have knee pain that limits daily life, the treatment may help you feel better while you’re in the pre-surgery rehabilitation period.
Goiânia, GoiásAges 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 - NCT06015620Recruiting
Health changes after mini gastric bypass surgery
This study looks at how mini gastric bypass surgery helps with obesity-related health problems and changes in body composition. It aims to see if patients experience improvements in conditions like diabetes or high blood pressure.
Bhubaneswar, OdishaAges 18–65 - NCT06057597Recruiting
Comparing two types of gastric bypass surgery for weight loss
This trial compares a new version of gastric bypass (with a longer 150cm bypassed segment) to the standard Roux-en-Y gastric bypass to see which leads to better weight loss and health improvements. It is for people with severe obesity who are already scheduled for surgery and want to help find the best procedure.
ParisAges 18–65 - NCT06132477RecruitingPhase 4
Study of GLP-1 medicines after weight loss surgery
This study looks at what happens when people taking a GLP-1 medication (like Ozempic) either stop or continue it after weight loss surgery. The goal is to learn whether staying on the medicine helps with long-term weight control.
Columbia, MissouriAges 18 years+ - 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 - 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+ - NCT06293703Recruiting
Leg length ratio and weight loss after gastric bypass
This study looks at how the length of different parts of your small intestine affects weight loss after Roux-en-Y gastric bypass surgery. It may help doctors tailor the surgery for better results.
Cleveland, OhioAges 18–70 - NCT06309563Recruiting
Essential amino acid diet for severe obesity
This study tests whether replacing some foods with essential amino acids (protein building blocks) can improve metabolism in people with severe obesity. It aims to find a non-surgical way to boost weight loss.
Oggebbio, VerbaniaAges 45–65 - NCT06530212Recruiting
Comparing two weight loss surgeries for severe obesity
This trial compares two types of weight loss surgery for people with severe obesity. Both procedures aim to help you lose weight and improve health conditions like diabetes or high blood pressure.
MinyaAges 18–65 - NCT06689241Recruiting
Comparing blood thinners to prevent clots after weight-loss surgery
This study compares two blood-thinning medications, rivaroxaban (a pill) and enoxaparin (a shot), to prevent dangerous blood clots after weight-loss surgery. If you are scheduled for bariatric surgery, this trial could help determine which approach works better for someone like you.
AlexandriaAges 20–60 - NCT06781229Recruiting
Gum bacteria in people preparing for weight loss surgery
This trial looks at the bacteria in the mouths of people with a BMI of 30 or higher who are scheduled for weight-loss surgery. The goal is to understand how gum health and body weight are connected.
ToulouseAges 18 years+ - NCT07051109Recruiting
Dual-chamber pain pump for recovery after weight-loss surgery
This trial tests a dual-chamber patient-controlled pain pump after weight-loss surgery. It may help women have better pain relief and recovery.
Seongnam-si, Gyunggi-doAges 19–65 - NCT07073846RecruitingPhase 4
Lidocaine and dexmedetomidine for pain after weight-loss surgery
This study tests whether adding two medicines (lidocaine and dexmedetomidine) to your anesthesia during weight-loss surgery can reduce pain, swelling, and stress on the body. It might help you have a smoother recovery.
Mexico City, Mexico CityAges 18–60 - NCT07098780RecruitingPhase 4
Tranexamic Acid to Prevent Bleeding in Weight Loss Surgery
This trial tests whether a medicine called tranexamic acid (TXA) can reduce bleeding during weight loss surgery. If you are having a sleeve gastrectomy or mini-gastric bypass, taking TXA may lower your risk of hemorrhagic events.
Karachi, SindhAges 18–60 - 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 - NCT07289555Recruiting
Customized SADI-S surgery after sleeve gastrectomy
This trial tests a new, customized version of a weight-loss surgery called SADI-S for people who had a sleeve gastrectomy before but need more help losing weight or keeping it off. The goal is to see how safe and effective this tailored surgery is.
Cairo, Greater CairoAges 18–65 - NCT02024542Recruiting
