Summary

This study tests whether restarting semaglutide (Wegovy) just two weeks after sleeve gastrectomy helps teens with severe obesity lose more weight than surgery alone. About 150 teens aged 12–18 who were already on semaglutide before surgery will be randomly assigned to restart the drug or receive standard care for 24 months. Researchers will track weight, blood sugar, and eating behaviors to see if early re-initiation is safe and effective.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Semaglutide (Wegovy) injection
What this could lead to
If it works, this could show that restarting semaglutide soon after weight-loss surgery helps teens lose more weight and improve their health long-term.
What could go wrong
This is a single-center trial with 150 participants, so results may not apply to all teens. Side effects like nausea or vomiting are common with semaglutide, and the study is not yet recruiting.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * ages 12 to 18 years * Tanner stage 3 or higher * severe obesity (defined as a BMI greater than 35 kg/m2 or BMI ≥140% of the 95th percentile) * currently undergoing primary surgical weight loss through the pediatric bariatric surgery pathway at Children's Hospital Los Angeles * be willing to have blood collected before and after surgical procedure at defined points * be willing to have clinical data entered into a prospective database; 8) presence of a consenting caregiver * be taking semaglutide 2.4 mg weekly as part of their routine medical care prior to surgery as part of their obesity treatment program, apart from any planned surgical procedure. Exclusion Criteria: * have a previous diagnosis of type 1 diabetes * taking any medications known to influence body composition or prevent weight loss or promote weight gain (e.g. prednisone) * have been diagnosed with syndromes or diseases that may influence the postoperative course (e.g., Cushing syndrome, Down syndrome, Prader Willi Syndrome) * have significant comorbid medical conditions necessitating frequent hospitalization that may require interruption of medications and/or that would make early re-initiation of semaglutide unsafe due to the other medical comorbidities * refuse to comply with eligibility criteria.
