- Summary:
- Semaglutide, the drug behind Ozempic and Wegovy, may have benefits that extend well beyond weight loss and diabetes. In a large Swedish study of nearly 15,000 people with bipolar disorder, its use was linked to a 21% lower risk of psychiatric hospitalization. Researchers think effects on inflammation and brain-related biological pathways could help stabilize mood, though other GLP-1 drugs did not show the same association.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs), widely used to treat diabetes and support weight loss, may also have benefits for mental health, particularly among people with bipolar disorder, according to new research from Griffith University.
Diabetes, obesity, and bipolar disorder frequently occur together and may share some underlying biological mechanisms. According to the latest World Health Organization estimates, about one in 200 people worldwide, or roughly 37 million people, live with bipolar disorder.
GLP-1 medications are already established treatments for diabetes and obesity, but their possible effects on bipolar disorder have remained unclear.
Large Study Examines GLP-1 Drugs and Bipolar Disorder
To investigate the connection, researchers led by Professor Mark Taylor from Griffith's School of Medicine and Dentistry analyzed nationwide Swedish data from nearly 15,000 people with bipolar disorder who had been prescribed GLP-1 medications over a 15-year period.
"People with bipolar disorder who were taking semaglutide (otherwise known as Ozempic or Wegovy), a type of GLP-1 medication, had significantly lower rates of psychiatric hospitalization compared with periods when they were not taking GLP-1 medicines," Professor Taylor said.
"The findings add to growing evidence that GLP-1 receptor agonists may have benefits beyond diabetes and obesity treatment, and could represent a promising new avenue for bipolar research."
The researchers found that semaglutide use was associated with a 21 percent lower risk of psychiatric hospitalization.
Semaglutide May Affect Brain-Related Processes
The findings suggest that GLP-1 signaling could help protect the brain by reducing inflammation, cellular stress, and other biological processes associated with bipolar disorder.
These effects could potentially contribute to greater mood stability and a lower risk of relapse.
However, the same pattern was not seen with every GLP-1 medication. Liraglutide and dulaglutide were not associated with a reduced risk of psychiatric hospitalization, indicating that any potential mental health benefit may not extend across the entire drug class.
Professor Taylor said he hopes the findings will now be examined in a randomized controlled trial, which would provide stronger evidence about whether semaglutide itself can improve psychiatric outcomes in people with bipolar disorder.

Executive Summary
Semaglutide, the active ingredient in Ozempic and Wegovy, was studied in a large Swedish cohort of nearly 15,000 individuals with bipolar disorder who had been prescribed GLP-1 medications over fifteen years. The research found that use of semaglutide was associated with a 21% lower risk of psychiatric hospitalization compared to periods when the individuals were not taking these medications. Researchers hypothesize that the potential mental health benefits stem from the drug's effects on inflammation and brain-related biological pathways, suggesting these mechanisms might help stabilize mood.
The findings suggest that GLP-1 receptor agonists may offer benefits beyond managing diabetes and weight loss, potentially opening new avenues for bipolar disorder research. It is important to note that this association was specific to semaglutide use; other GLP-1 medications, such as liraglutide and dulaglutide, did not show a corresponding reduction in the risk of psychiatric hospitalization. Therefore, any mental health benefit appears specific to semaglutide rather than the entire class of GLP-1 drugs.
