BARIATRIC SURGERY

This study looks at whether sewing shut a specific incision site (the epigastric trocar) during sleeve gastrectomy can prevent hernias from forming later. People having their first sleeve gastrectomy for obesity are included, while those with prior stomach banding or repeat sleev…

This study aimed to see if blocking blood vessels to part of the stomach (bariatric embolization) could help super obese patients lose weight before sleeve gastrectomy surgery, potentially lowering surgical risks. It planned to enroll patients with a BMI over 50 and at least thre…

This study looks at whether giving tranexamic acid (a drug that helps blood clot) during weight-loss surgery can reduce dangerous bleeding. About 1000 adults having bariatric surgery will be split into two groups: one gets the drug, the other gets standard care. The goal is to se…

This study looks at whether a low dose of esketamine, given during and after weight-loss surgery, can help reduce depression in patients who were already depressed before surgery. Forty adults with a BMI over 35 and a Hamilton Depression score of 7 or higher are taking part. The …

This study looks at whether two types of exercise training can improve body composition, heart and lung function, and quality of life in people who have had bariatric surgery. Researchers will compare high-intensity interval training (HIIT) and moderate-intensity continuous train…

This study compares two types of weight-loss surgery—sleeve gastrectomy alone versus sleeve gastrectomy with transit bipartition—to see which leads to fewer cases of dumping syndrome (nausea, diarrhea, dizziness after eating) and better quality of life. Researchers will follow 20…

This study looks at how the foods people eat after bariatric surgery relate to inflammation in the body and stomach problems like bloating and gas. Researchers will collect diet records, blood samples, and symptom reports from 70 adults who had surgery at least 3 months ago. The …

This study was designed to see how well the stomach-acid drug dexlansoprazole is absorbed before and after gastric bypass surgery, and how often ulcers occur afterward. It planned to enroll smokers with obesity who were scheduled for surgery. However, the study was withdrawn befo…

This study looks at 49 adults who had bariatric surgery at least 5 years ago and later regained weight or didn't lose enough. Researchers want to understand how disordered eating, emotional eating, and nutrition affect weight regain. The goal is to help create better follow-up ca…

This study looks at how different doses of glucagon, a natural hormone that raises blood sugar, affect people who have low blood sugar after weight-loss surgery. Researchers will give 28 participants several doses of glucagon and measure their blood sugar and hormone levels. The …

This study follows 14 adults who had a second weight-loss surgery (conversion bariatric surgery) because they didn't lose enough weight or regained weight after their first surgery. Researchers will measure changes in weight, body fat, muscle, and blood tests over one year. The g…

This study looks at whether changing what you eat can help people lose more weight after bariatric surgery. Researchers will track hunger, calorie intake, and energy use in 44 patients who had sleeve gastrectomy. The goal is to find better ways to support long-term weight loss af…

This study compares the eating habits of 44 people who had sleeve gastrectomy surgery for obesity. Researchers want to understand why some patients lose more weight than others by looking at hunger, appetite, and related hormones. The goal is to find dietary patterns that lead to…
