Recruiting studies
- NCT01998750Recruiting

Light therapy for gum disease in people with obesity
This study tests whether adding a special light-activated cleaning (antimicrobial photodynamic therapy) to standard gum disease treatment can help people with obesity who have gum disease. It aims to see if this extra step improves gum health more than standard treatment alone.
Bauru, São PauloAges 18–70 - NCT04578652RecruitingPhase 3
Test fiber plus metformin for teen weight and insulin resistance
This trial studies whether adding fiber to metformin helps teens with severe obesity and insulin resistance improve how their bodies handle sugar. You might consider it if you’re a teen who isn’t yet diagnosed with type 2 diabetes and meets the specific lab and health criteria.
Edmonton, AlbertaAges 12–18 - NCT05982847Recruiting
Blood pressure check for kids in South Africa
This study checks blood pressure in children ages 5 to 17 across South Africa. It aims to find normal blood pressure ranges and improve healthcare for kids.
Mthatha, Eastern CapeAges 5–18 - NCT05975541Recruiting
Infection risk in obesity and type 2 diabetes
This study looks at how obesity and type 2 diabetes affect your body's ability to fight infections. By joining, you'll help researchers understand why some people with these conditions get more infections, which could lead to better prevention and treatment.
Novara, NovaraAges 18–65 - NCT05962372Recruiting
Culturally tailored diet program for adults in Puerto Rico
This study tests a diet program designed to fit Puerto Rico culture and daily life. It may help adults with weight or blood sugar or blood fat concerns improve their health through regular check-ins.
San JuanAges 30–65 - NCT05945355Recruiting
Study of breathing training for children with asthma
This study looks at how an asthma-specific breathing training program affects children’s breathing and asthma control. It may help your care team understand who could benefit from inspiratory (breathing-in) training.
Durham, North CarolinaAges 6–17 - NCT05933499RecruitingPhase 2
Tirzepatide and bimagrumab for body fat and insulin sensitivity
This Phase 2 study tests two medicines to see how they change body fat, insulin sensitivity, and bone health in adults with obesity. It may help people who have tried lifestyle changes to lose weight but have not been able to, though diabetes and several health conditions must be ruled out first.
Boston, MassachusettsAges 18 years+ - NCT05918575Recruiting
Breathing support after a breathing tube in very obese adults
This trial tests whether giving noninvasive breathing support (using a mask or similar device, without a new breathing tube) right after removing a breathing tube works better for severely obese adults. It mainly looks at people at higher risk of needing help breathing again after extubation.
Chicago, IllinoisAges 18 years+ - NCT05906238Recruiting
Study to reduce harm from obesity stigma
This trial looks at ways to lessen the negative effects that people may experience from weight-related stigma. It’s meant to help improve well-being for people living with obesity.
Poitiers, VienneAges 18 years+ - NCT05857150Recruiting
Study tests exercise effects in adults with obesity
This study looks at how your body responds to exercise if you have obesity. It may help researchers understand which changes happen with exercise and how safe it is for people in your age group.
Rochester, MinnesotaAges 20–45 - NCT05798676Recruiting
Study of pregnancy factors linked to a child’s growth
This study looks at breastfeeding mothers and how a mother’s pregnancy and health factors may relate to a child’s growth and body fat. You might be able to join if you were normal weight or overweight/obese before pregnancy and you meet the pregnancy and delivery health requirements.
La Plata, Buenos AiresAges 18–40 - NCT05747976Recruiting
Study for children with very high body size measurements
This study is building a program database for children who have unusually high body size measurements for their age. By collecting genetic and health information, researchers hope to better understand causes of obesity and guide care.
Houston, TexasAges Any age - NCT05745441Recruiting
Dinner routine study for weight and prediabetes health
This study tests whether changing your dinner timing and routine can improve health related to weight and blood sugar in people with obesity and prediabetes (or healthy weight). You’ll follow a set dinner schedule and complete study visits while the team monitors outcomes.
Baltimore, MarylandAges 18–50 - NCT05703347Recruiting
Mobile app coaching to improve sleep and prevent childhood obesity
This study tests a mobile health app that helps children get better sleep, aiming to support healthier weight over time. It is designed for children who are getting less sleep than recommended and are in the higher-but-not-highest weight range for their age.
Philadelphia, PennsylvaniaAges 8–12 - NCT01129297Recruiting
Severe obesity tissue study during surgery
This study collects small tissue samples during certain abdominal surgeries to better understand what drives severe obesity and related blood-sugar patterns. If you agree to the extra sampling, your information and samples may help researchers build a “biological atlas” that could guide future treatments.
Lille, NordAges 18–65 - NCT05242835Recruiting
Study for weight regain after sleeve stomach surgery
This trial studies a specific type of metabolic (weight-related) surgery for people whose sleeve gastrectomy did not lead to enough weight loss or has caused significant weight regain. It may help improve long-term weight and related health problems.
Québec, QuebecAges 18–60 - NCT05611697Recruiting
Compare two weight-loss surgeries for severe obesity
This trial compares two types of bariatric (weight-loss) surgery to see which helps people with severe obesity lose weight and stay healthy. You might be eligible if you’re between 20 and 60 and are already being referred for bariatric surgery after prior unsuccessful weight-loss attempts.
Tønsberg, VestfoldAges 20–60 - NCT05589688RecruitingPhase 1
Personalized acyclovir dosing in overweight and obese volunteers
This Phase 1 study tests how to adjust acyclovir dosing based on body weight and kidney function. It includes healthy volunteers across normal weight, overweight, and obesity levels to better understand how the drug moves through the body.

Two blood-thinner schedules for clot prevention in very obese surgery patients
This study compares two different schedules of bemiparin (a blood thinner) to prevent dangerous blood clots after surgery in people with very high body weight. It may help find the safest and most effective dose/timing for clot prevention around the time of surgery.
Erbil, Kurdistan RegionAges 18–90 - NCT04087655Recruiting
Study obesity and tiny blood-vessel function in women
This study looks at how obesity affects tiny blood vessels and blood flow. It also checks whether a specific training/exercise approach changes these “microvascular” effects in premenopausal women who fit certain metabolic risk criteria.
Tallahassee, FloridaAges 18–45 - NCT05364957Recruiting
Gastric balloon plus asthma care for uncontrolled asthma and obesity
This study tests whether placing a soft “balloon” inside the stomach (intragastric balloon) can help people who have uncontrolled asthma and obesity. It also checks whether the balloon is safe and can improve asthma control when standard inhaler treatment is already in use.
