Initiating anti-obesity medications (AOMs) more than 12 months after bariatric surgery is associated with a significantly lower risk of adverse events compared to initiating them within the first 12 months.

If you are considering weight loss medication after bariatric surgery, current evidence suggests that waiting until at least 12 months post-surgery to start the medication is associated with a significantly lower risk of adverse events compared to starting within the first year. This may allow for better surgical recovery before adding pharmacological stress.

AOM initiation ≥12 months after surgery was associated with lower risk of AEs compared to <12 months (aOR 0.01 [95% CI 0.0–0.01]; p < 0.001).
