Obesity (bmi>30)

This pilot study tests whether endoscopic sleeve gastroplasty (ESG), a minimally invasive procedure that reduces stomach size, can help obese adults with heart failure with preserved ejection fraction (HFpEF). Researchers will measure changes in heart failure symptoms and weight …

This trial tests whether taking vitamin C, vitamin E, or both daily for 12 weeks can lower markers of brain inflammation and change appetite-related brain signals in Mexican adults with obesity. Participants are randomly assigned to one of the supplements or a combination, and re…

This trial tests whether a weight-loss procedure called endoscopic sleeve gastroplasty (ESG) can improve blood sugar control and reduce the need for insulin in adults with obesity and type 2 diabetes. Participants have poorly controlled diabetes despite taking standard medication…

This trial tests whether adding inositol or metformin to either a Mediterranean or low-carbohydrate diet improves insulin resistance in obese women with polycystic ovary syndrome (PCOS). About 90 to 102 participants will be randomly assigned to one of six groups and followed for …

This study evaluates the safety and effectiveness of the Allurion Gastric Balloon System, a swallowable balloon placed in the stomach to help with weight loss. It involves 250 adults aged 22–65 with a BMI between 30 and 40. The balloon is swallowed and later passes naturally, avo…

Researchers are testing whether mazdutide, a weekly injected drug, reduces the number of gout flares in adults who have both obesity and gout. The study enrolls 30 people aged 18 to 65 with a BMI of at least 30 and at least two gout flares in the past six months. Everyone receive…

This phase 2 trial tests whether semaglutide, a weekly injection already used for weight loss, can reduce chronic low back pain in adults with obesity. Researchers will compare semaglutide to a placebo over 52 weeks in 250 participants, measuring changes in pain severity, disabil…

Researchers at a French sleep center are studying adults with obesity who are referred for a sleep study because of suspected obstructive sleep apnea. The team measures how much carbon dioxide builds up in the blood overnight using a skin sensor, then compares that cumulative exp…

This early-phase study will test how insulin given as a nasal spray affects nerve activity and blood flow in the brain and legs. Researchers will compare 64 adults with obesity and insulin resistance to healthy-weight individuals. The goal is to understand how obesity changes the…

This study investigates how taurine—a natural amino acid linked to inflammation and cell health—differs between metabolically healthy and unhealthy older women with obesity. Researchers will measure taurine levels before and after a 16-week combined exercise program. The goal is …

This study looks at how incretin-based therapies (like GLP-1 drugs used for weight loss) affect breathing in people with obesity. Researchers will analyze data from 48 adults aged 25-60 with a BMI of 30 or higher. They will use machine learning to find patterns that predict impro…

This study will test whether a therapeutic patient education program is acceptable and useful for adults living with obesity and related conditions like diabetes or joint problems. About 42 participants will take part in a one-day group session and follow-up workshops, then answe…

This study will compare weight-loss plans made by ChatGPT with those made by a human dietitian. 21 adults with obesity will be split into three groups: one gets AI-only advice, one gets a dietitian's plan, and one gets a combination of both. The goal is to see which approach lead…
