A recent study has shown that bariatric surgery is significantly more effective for weight loss compared to popular GLP-1 drugs, which are commonly prescribed for obesity management. The research was presented at the American Society for Metabolic and Bariatric Surgery scientific meeting and collected data from over 51,000 patients who either underwent weight-loss surgery or received injectable medications between 2018 and 2024.
Patients, who had bariatric surgery, including procedures like gastric bypass and sleeve gastrectomy, lost an average of 24% of their initial weight three years after the operation. In contrast, those treated with GLP-1 drugs—specifically semaglutide or tirzepatide—experienced much lower weight loss, averaging only about 5% after six months and around 7% after a year of treatment.
The lead researcher, Dr. Avery Brown from NYU Langone Health, noted that earlier clinical trials had shown more significant weight loss with GLP-1 drugs, with reductions typically between 15% to 21%. However, the differences in real-world efficacy highlight the limitations of these medications when prescribed in everyday clinical settings. Additionally, the study revealed that nearly 70% of patients receiving GLP-1 drugs tend to stop treatment within the first year, which may contribute to their lower average weight loss.
Experts in the field, including Dr. Ann M. Rogers, the president of ASMBS, emphasized that while both surgical and drug treatments can aid weight loss, surgical options provide a more effective and durable solution for individuals who struggle to achieve sufficient weight loss through medication alone. This study underscores the importance of evaluating treatment options, especially for patients who experience side effects from GLP-1 medications or face challenges with compliance due to costs or other factors.
In light of these findings, medical professionals may consider bariatric surgery as a viable option for patients who do not meet their weight-loss goals with pharmacological interventions alone. The relationship between treatment type and long-term weight management outcomes illustrates the need for individualized patient care and the potential to combine both surgical and non-surgical methods to enhance effectiveness.
