Frequently Asked Questions
What is the difference between GLP-1 medications and bariatric surgery?
GLP-1 medications reduce appetite and slow stomach emptying through hormone mimicry, without physically changing the stomach. Bariatric surgery physically changes hunger hormones and stomach size, which often leads to greater and more durable weight loss. If you are deciding between two specific GLP-1 medications rather than between medication and surgery, see our comparison of Mounjaro and Zepbound.
Do I have to stay on GLP-1 medications forever?
Many patients need to remain on GLP-1 medications for years, potentially for life, to maintain their results. Research shows that many patients regain significant weight after stopping these medications.
How much weight can I expect to lose with bariatric surgery?
Many bariatric surgery patients lose 60 to 80 percent of their excess body weight. Patients often also see significant improvement in conditions like type 2 diabetes, sleep apnea, and high blood pressure.
Is bariatric surgery safe?
Modern bariatric surgery has become remarkably safe due to advances in surgical technology, minimally invasive techniques, and anesthesia. At St. Louis Bariatrics, patients also receive thorough evaluations, education, and long-term follow-up care.
