Popular GLP-1 medications approved for weight loss, diabetes, and heart disease may have untapped potential to treat substance abuse disorders, psychosis, infections, cancer and dementia, a sweeping new study shows.

In all, researchers found that people taking GLP-1 medications had lower risks for 42 health outcomes, including liver failure, lung failure, cardiac arrest, aspiration pneumonia and shock.

Over 2 million people were included in new research to test these drugs against 175 different health outcomes.
