These diabetes and weight-loss drugs might be affecting the parts of your brain that control how you feel emotionally.
People with type 2 diabetes who take GLP-1 drugs like Ozempic might feel a little better emotionally, but the mood boost is small and doesn’t show up in every study.
Certain diabetes and weight-loss drugs like semaglutide and dulaglutide might help reduce binge eating, especially in people with binge eating disorder, by affecting how the brain handles rewards.

Weight-loss drugs like Ozempic don’t seem to raise suicide risk for most people, but there might be a warning sign for those also taking antidepressants or anxiety meds.
