TrondheimAges 18–70 - NCT03497143Recruiting
Gastric bypass or sleeve surgery and lamotrigine drug levels

TrondheimAges 18–70 - NCT03497156Recruiting
Tests drug absorption after stomach bypass or sleeve surgery
This study checks how a blood-pressure medicine called lercanidipine is absorbed by the body after gastric bypass or sleeve gastrectomy. You may be able to join if you are preparing for one of these surgeries in Central Norway.
TrondheimAges 18–70 - NCT03517072Recruiting
Study of long-term success after bariatric surgery
This study looks at what helps people do well in the long run after bariatric (weight-loss) surgery. You may be able to join if you had the surgery about five years ago and are willing to participate.
ArrasAges Any age - NCT03519893Recruiting
Study of blood pressure drug handling after weight-loss surgery
This study looks at how losartan (a blood pressure medicine) moves through the body after gastric bypass or sleeve gastrectomy. It may help doctors better choose and dose blood pressure treatment after weight-loss surgery.
TrondheimAges 18–70 - NCT03519906Recruiting
Bariatric surgery study measuring how metoprolol is absorbed
This study looks at how metoprolol (a blood-pressure medicine) gets absorbed in the body before and after bariatric weight-loss surgery. If you’re preparing for gastric bypass or sleeve surgery, this may help researchers understand dosing and medicine absorption changes after surgery.
TrondheimAges 18–70 - NCT03532477Recruiting
Venlafaxine medicine study around weight-loss stomach surgery
This study looks at how the antidepressant venlafaxine is absorbed in the body when people undergo gastric bypass or sleeve gastrectomy. It may help doctors understand whether dosing should change after surgery.
TrondheimAges 18–70 - NCT03535142Recruiting
Fatty liver in people considering bariatric surgery
This study looks at how fatty liver disease may predict future liver health in people with severe weight gain. It compares people who are planning bariatric (weight-loss) surgery with similar people who are not, to better understand who may be at higher risk.
EsbjergAges 18 years+ - NCT03535376Recruiting
Studies how valsartan works after bariatric surgery
This study looks at how the blood-pressure medicine valsartan is absorbed and processed in your body after gastric bypass or sleeve surgery. It may help doctors choose safer, more effective dosing after weight-loss surgery.
TrondheimAges 18–70 - NCT03538457Recruiting
Gastric bypass or sleeve surgery and paracetamol absorption
This study looks at how your body absorbs paracetamol (acetaminophen) after planned weight-loss surgery. It may help doctors better guide pain- and fever-medication dosing after gastric bypass or sleeve gastrectomy.
TrondheimAges 18–70 - NCT03554902Recruiting
Endoscopic procedure for gastric tubulization
This trial is for people who are already planned to have a specific stomach (gastric) procedure using an endoscope (a flexible camera). It mainly aims to study how this procedure is done and how patients do afterward.
StrasbourgAges 18–65 - NCT03868592Recruiting
Weight loss study in people with very high body weight
This trial looks at how to support long-term weight loss and improve how your body handles fat breakdown. It may help people who have severe obesity after bariatric (weight-loss) surgery, but it has several health and lifestyle limits.
Rochester, MinnesotaAges 18–65 - NCT03875625Recruiting
Tracking body fat and liver fat after weight-loss treatment
This study looks at how body fat and liver fat change after bariatric (weight-loss) surgery or a lifestyle program. You may join if you have overweight or obesity and can safely have MRI scans, so researchers can compare results between treatment approaches.
Hong Kong, ShatinAges 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 - NCT04326192Recruiting
Spinal cord stimulation to reduce stubborn back and leg pain
This trial tests whether spinal cord stimulation (a treatment where a device sends mild signals to the spinal cord) can improve persistent nerve-type back and leg pain. It is mainly for adults who are already planning to try spinal cord stimulation but have not tried it before.
Portland, OregonAges 21–70 - NCT04422405Recruiting
One-anastomosis stomach bypass study for reflux and stomach changes
This study looks at how a one-anastomosis gastric bypass changes how your stomach and esophagus work, especially relating to acid reflux. You may be offered the planned surgery if you fit the weight and heartburn/reflux-related conditions, and the team will measure changes before and after.
Schlieren, Canton of ZurichAges 18–65 - NCT04894838Recruiting
Testing a bypass revision surgery for weight regain
This study looks at whether a specific stomach bypass revision (a “distal gastric bypass”) can improve outcomes after Roux-en-Y gastric bypass when weight loss was not enough or weight was regained. You may be considered if you meet weight-loss goals criteria and can join follow-up and possibly surgery.
Arnhem, GelderlandAges 18–65 - NCT04945473Recruiting
Testing weight-loss surgery follow-up and gastric “recalibration”

StrasbourgAges 18–75 - NCT05000996Recruiting
Gut microbiome study for people having metabolic surgery
