The Facts

  • Weight-loss jabs like Ozempic and Wegovy may be effective at treating mental health issues in addition to curbing patients' appetite, according to a new study published by scientists from the University of Bern.
  • Across 36 studies involving 26,000 adults in 19 different countries, the scientists reviewed the impact of four weight-loss drugs (semaglutide, liraglutide, exenatide, and dulaglutide), concluding that they were "effective weight loss treatment options for patients with mental illness."
  • The medications, known as GLP-1 receptor agonists, work by mimicking gut hormones that regulate hunger while potentially offering anti-inflammatory and anti-oxidative properties that could reduce neuroinflammation.

The Spin


Narrative A

The studies show that weight-loss drugs can serve a dual purpose, improving physical and mental health at the same time. The benefits this could bring could revolutionize treatment approaches for millions of patients, especially those who have mental illness, who are three times as likely to suffer from obesity.

Narrative B

While the results are promising, additional evidence is needed to fully evaluate the impact weight loss drugs can have on physical and mental health. There is not enough data to make a definitive link that GLP-1 receptor agonists can perform this dual role in the long term, making further studies a top priority.
