Comparing Weight-Loss Surgery and GLP-1 Drugs for Effectiveness and Cost in Treating Obesity

Bariatric surgery achieves 10-year total weight loss rates of 23.4% for sleeve gastrectomy and 26.9% for gastric bypass.

• More complex procedures, such as duodenal switch, result in even greater total weight loss.
• Glucagon-like peptide-1 receptor agonists (GLP-1 RA) can lead to up to 25.3% total weight loss with tirzepatide.
• GLP-1 RA effectiveness is generally lower than that of bariatric surgery and is associated with high discontinuation rates due to adverse effects.
• Less than 1% of eligible patients undergo bariatric surgery annually, despite its superior long-term outcomes.
• GLP-1 RA may provide a treatment option for patients who are hesitant or ineligible for surgery.
• A multidisciplinary approach combining surgical, pharmacological, and lifestyle interventions is important for effective obesity management.
