Negative pressure wound dressings after breast reconstruction in obesity

You may be more likely to benefit if you’re at higher risk for wound problems after abdominal flap surgery.

Tallahassee, FloridaAges 18–45 - NCT04095117Recruiting
Measure belly size to predict epidural depth in obesity
This study checks whether a measurement of belly size can help predict how deep an epidural needs to go in people with obesity. It may help make epidural placement safer and more accurate during planned leg surgeries.

Hypnosis during noninvasive breathing support for ICU lung illness
This trial tests whether hypnosis can help people in the ICU who need noninvasive breathing support (breathing help without a tube) for breathing flare-ups related to COPD and/or obesity. It aims to make this treatment easier and safer while you are awake.
Rennes, Brittany RegionAges 18 years+ - NCT04232566Recruiting

Edmonton, AlbertaAges 12–18 - NCT04597281Recruiting
Mediterranean diet program for young children at risk of obesity
This trial tests whether a Mediterranean-style eating pattern can help prevent weight problems in young children who are at higher risk. It’s meant for children with normal weight or mild overweight and whose parents have higher body weight, without other medical reasons for weight gain.
CórdobaAges 3–7 - NCT04604626Recruiting
Study rare obesity linked to eating and brain conditions

You may be invited if your case includes clues from your history or symptoms, and you can consent to genetic testing discussions as part of usual care.
La DefenseAges Any age - NCT04613791Recruiting
Alcohol and addictive behaviors in people with obesity
This study looks at how often people with obesity struggle with alcohol or other addictive behaviors, and how these issues change over time. Understanding this connection may help doctors better support patients managing obesity.
