This study is testing if metformin, a common diabetes medication, can help obese people who don't have diabetes lose weight and reduce their risk of heart disease. Researchers are enrolling 220 Black Nigerian adults to compare metformin against a placebo pill. The goal is to see …

This study is testing whether a minimally invasive endoscopic procedure to reduce stomach size, combined with lifestyle changes, is better than lifestyle changes alone for treating a serious fatty liver disease called MASH in people with obesity. Researchers will compare the two …

This study is testing whether a 10-week exercise program delivered through video calls (telemedicine) can improve heart and lung fitness and insulin sensitivity in Asian children aged 12-17 who have low fitness levels. Researchers will compare the online program to standard activ…

This study is testing whether taking glutamine, a common amino acid, as a powder for 8 weeks can help improve blood sugar control and ease irritable bowel syndrome (IBS) symptoms in people with obesity. It will involve 110 participants who will be randomly assigned to receive eit…

This study is testing whether a 6-month physical activity program can improve hormone health and lower the risk of developing diabetes in girls aged 8-12 who are at higher risk. It compares a full program with health coaching and text messages to a lighter program with just text …

This study aims to understand a puzzle in early diabetes: why the liver might stop responding to insulin's signal to lower blood sugar but keep making fat. Researchers will give a single dose of a drug called alpelisib or a placebo to healthy adults and adults at risk for type 2 …

This study aims to understand why people with type 2 diabetes are more likely to develop heart failure. Researchers will observe 500 participants with heart failure, some with and some without diabetes, to see how their heart cells produce energy. The goal is to gather knowledge …
