GLP-1 receptor agonists (GLP-1RAs) do not increase the risk of adverse events compared to non-GLP-1RA antiobesity medications in patients who have undergone bariatric surgery.

If you have had bariatric surgery and are considering GLP-1 medications (like semaglutide or liraglutide) for weight regain, current data suggests they are not more likely to cause adverse events than older weight loss medications. However, the study notes that starting these medications more than 12 months after surgery is associated with a significantly lower risk of adverse events compared to starting them within the first year.

Our results showed that GLP-1RA AOMs were not associated with an increased risk of AEs compared to non-GLP-1RA AOMs in patients who had previously undergone bariatric surgery.
