Abstract
PURPOSES: The increasing use of bariatric surgery in adolescents has raised some concerns regarding the postoperative outcomes and the optimal time of surgery at young ages. However, no study has yet compared the weight loss and comorbidity resolution following bariatric surgery between adolescents and young adults. METHODS: This study was conducted on a case group of adolescents (aged 11-18) and a control group of young adults (aged 19-29) undergoing bariatric surgery (sleeve gastrectomy or gastric bypass). The two groups were matched in terms of gender, body mass index (BMI), and surgery type and were assessed regarding the surgical outcomes at 1 year after surgery. RESULTS: The baseline characteristics of the adolescents (n = 118, mean age: 17.0 ± 1.6 years) and young adults (n = 236, mean age: 25.2 ± 3.2 years) were similar, as well as surgery-associated complications. The mean loss of BMI (- 15.4 ± 3.6 vs. -15.8 ± 4.6 kg/m2) and 12-month percentage of excess weight loss (80.4 ± 20.1 vs. 80.2 ± 20.1%) were similar in the two groups. Both groups showed parallel reductions in the cardiovascular risk factors. The remission of hypertension, diabetes mellitus, and dyslipidemia was similar between the groups. The increase in the hemoglobin level and copper deficiency was greater in young adults, whereas the increase in ferritin deficiency was greater in adolescents. CONCLUSION: Similar to young adults, bariatric surgery is an effective and safe method to achieve weight loss, resolve obesity-related comorbidities, and improve cardiovascular risk factors in the adolescents.
