Recruiting studies
- NCT04791371Recruiting
Study how fitness and insulin resistance relate to diabetes
This study looks at how low physical activity, insulin resistance in small blood vessels, and cardiorespiratory fitness connect to diabetes and blood sugar control. You may be eligible if you are generally sedentary and fit within the weight range, and if you do not have certain heart, lung, nerve, or medication factors.

Study how exercise changes body fat and metabolism
This study looks at how starting exercise changes the structure and function of body fat. It may help you understand how exercise affects things like cholesterol and blood sugar, even if you’re not currently exercising regularly.
Ann Arbor, MichiganAges 18–40 - NCT04841057Enrolling by invitation
Study of blood and stool changes after weight-loss surgery
This study looks at how your body’s metabolism changes after a specific weight-loss surgery (gastric bypass). It may help researchers better understand what to expect and how to tailor care, while requiring blood draws and stool samples before and after surgery.
Columbia, MissouriAges 18–80 - NCT04851470Recruiting
Dental gum check in adults with obesity
This study looks at gum health in adults with obesity. It may help researchers understand how weight and related health factors affect periodontal (gum) status and what to monitor in bariatric care populations.
LondonAges 18 years+ - NCT04708535Enrolling by invitation
Study how fat changes affect insulin resistance after bariatric surgery
This study looks at how your body’s fat under the skin and inside the abdomen may affect “insulin resistance,” a common problem linked with blood sugar control. It’s for people who are scheduled for bariatric (weight-loss) surgery, to learn more before and after surgery.
Stanford, CaliforniaAges 30–65 - NCT04603859Recruiting
When to induce labor for people with higher weight
