Combination anti-obesity medications (AOMs) are more effective than monotherapy for treating weight regain after bariatric surgery, with patients prescribed three or more AOMs losing significantly more weight than those on one.

If you have regained weight after bariatric surgery, taking just one weight-loss medication may not be enough. This study suggests that using a combination of anti-obesity medications, along with lifestyle changes, leads to significantly greater weight loss than using a single medication. Talk to your doctor about whether a combination approach is right for you, keeping in mind that access and cost can be barriers.
