Is it true GLP-1 medications were originally just diabetes drugs that got "repurposed" for weight loss?

Fact. GLP-1 receptor agonists were first developed and approved for type 2 diabetes management, and weight loss was noticed as a beneficial side effect in diabetes trials, which led to dedicated research and eventual approval of higher-dose versions specifically for chronic weight management (like Wegovy and Zepbound). So the "repurposed" framing is accurate, it's not spin, it reflects the actual drug development history.
