A new study from researchers at LSU’s Pennington Biomedical Research Center, FMOL Health | Our Lady of the Lake Regional Medical Center, and the Metamor Institute found that metabolic and bariatric surgery can be delivered safely and effectively for adolescents and young adults living with severe obesity, leading to significant weight loss and improvements in obesity-related health conditions.
Published in Obesity Surgery, the study examined outcomes from 76 patients ages 10 to 25 who underwent bariatric surgery through a Louisiana-based program at the Metamor Institute between January 2020 and March 2025. Researchers evaluated safety outcomes as well as longer-term health improvements associated with surgical obesity treatment.
The study found that patients achieved an average total body weight loss of 29%-32% maintained over one to five years. Among patients with available follow-up data, 94% experienced remission of type 2 diabetes, 67% showed improvement in hypertension and dyslipidemia and 64% experienced improvement in gastroesophageal reflux disease. Surgical complications remained low, with only 5% of patients experiencing complications within 30 days of surgery.
Researchers noted that these outcomes were likely supported by a comprehensive, multidisciplinary care model that included experienced surgeons, nutritional guidance, behavioral support and coordinated medical follow-up. The study population represented a broad cross-section of Louisiana patients, with nearly 75% covered by Medicaid, highlighting the importance of ensuring access to effective obesity treatment options across socioeconomic backgrounds.
The findings support current American Academy of Pediatrics recommendations that adolescents age 13 and older with severe obesity and related health risks be evaluated for metabolic and bariatric surgery as part of comprehensive, evidence-based obesity care.
