Background and Aim: The prevalence of obesity among adolescents has risen globally, including in Iran. Obesity during adolescence is associated with severe physical and psychological health issues, such as cardiovascular risks and metabolic disorders. Bariatric surgery has emerged as a promising treatment for morbid obesity in adolescents, offering significant weight loss and improvement in comorbidities. However, concerns remain regarding its long-term impact on micronutrient deficiencies and overall health. This study investigates the short-term outcomes of bariatric surgery in adolescents under 18 years. Methods: This prospective cohort study was conducted as part of Tehran Obesity Treatment Study TOTS. Adolescents aged 11–18 years (n = 118) with a body mass index (BMI) ≥35 kg/m² (with comorbidities) or ≥40 kg/m² were included. Participants underwent sleeve gastrectomy (SG) or gastric bypass (GB) and were followed for one year post-surgery. Data collection included anthropometric measurements, cardiovascular risk factors, micronutrient levels, and surgical complications. A calorie-restricted diet and vitamin/mineral supplementation were provided postoperatively. Results: 1. Anthropometric Changes: • Mean BMI reduction: 15.4 ± 3.6 kg/m² • Mean weight loss: 43.6 ± 11.2 kg • Waist circumference reduction: 30.3 ± 12.6 cm • Excess weight loss percentage (EWL%): 80.4 ± 20.1% 2. Cardiovascular Risk Factors: • Significant reductions in systolic blood pressure (SBP), diastolic blood pressure (DBP), triglycerides (TG), total cholesterol (TC), and LDL-C. • Increase in HDL-C levels. • Complete remission of diabetes mellitus (DM) and hypertension (HTN) one year post-surgery. 3. Micronutrient Deficiencies: • Increased prevalence of ferritin deficiency post-surgery . • iron, zinc, calcium, phosphate, vitamin B12, and 25(OH) vitamin D deficiencies did not significantly change after surgery. 4. Surgical Complications: • No mortality or conversion to open surgery. • Low readmission rates n=3(2.5 %), bleeding n=2 Stricture n=1. Conclusion: The findings indicate that bariatric surgery is a safe and effective treatment for adolescents under 18 with severe obesity, resulting in significant weight loss and improvement in obesity-related health issues within one year. While early intervention shows considerable benefits, the rise in ferritin deficiency emphasizes the necessity for ongoing monitoring of micronutrient levels. Further research is essential to evaluate long-term outcomes and enhance postoperative care.
