Researchers compare two weight-loss operations in adults with Class IV obesity, defined as a body mass index of 50 or higher. One group receives standard sleeve gastrectomy, where surgeons remove most of the stomach. The other receives the same operation plus a polypropylene band…

This study tests whether specialized bariatric supplements (Elan Believe, Compass, Supreme) prevent vitamin and mineral deficiencies after weight-loss surgery better than standard over-the-counter multivitamins. Over 600 adults undergoing sleeve gastrectomy, gastric bypass, or on…

This study tests whether a daily multivitamin tablet can prevent vitamin and mineral deficiencies in people using GLP-1 drugs (like Ozempic or Saxenda) for weight loss. These drugs suppress appetite, which can lead to low nutrient intake. The trial will compare a multivitamin to …

This study tested two video-guided devices (CMAC D-Blade and CMAC Video Stylet) in 150 obese adults undergoing bariatric surgery. The goal was to see which device allows doctors to place a breathing tube more easily and safely on the first try. Participants had a higher risk of d…

This study tested whether taking oral collagen supplements can increase collagen in the skin of people who had weight-loss or tummy-tuck surgery. 102 participants received either collagen peptides or a placebo for several weeks. Researchers then compared skin biopsies and scar qu…

Weight-loss surgery like sleeve gastrectomy can cause significant muscle loss, not just fat loss. This study follows 110 adults for 18 months after surgery to see how muscle mass changes and whether certain blood markers, called myomiRs, along with routine lab tests, can track th…

This study follows 160 people for 12 months after laparoscopic sleeve gastrectomy to measure changes in two hormones made by fat tissue: asprosin and neuregulin 4. Asprosin rises with obesity and insulin resistance, while neuregulin 4 falls, and researchers want to see if their s…

This study looks at stomach tissue from 100 obese patients undergoing weight-loss surgery and compares it to tissue from lean individuals. Researchers are counting immune cells called macrophages and mast cells, as well as blood vessel density, to see if obesity-related inflammat…

This study tests whether giving people special supplements designed for their type of weight-loss surgery can help keep their vitamin levels healthy. After bariatric surgery, the body absorbs nutrients differently, which can lead to both deficiencies and, from too many supplement…

This completed study looked at 60 people with obstructed defecation, a severe form of constipation. Researchers compared how well a noninvasive nerve stimulation treatment worked in obese versus non-obese participants. The goal was to see if body weight changes the treatment's ab…
