GLP-1 is a hormone your gut releases after you eat. It tells the brain you are full and helps control blood sugar. Drugs that mimic it, like Ozempic, became the most talked-about medicines of the decade.

The science goes back decades. Researchers mapped how the hormone works and turned that knowledge into medicines that help millions lose weight and manage diabetes. The discovery is now tipped for the Nobel Prize in Medicine, announced today.

The favourites include Joel Drucker, Jens Juul Holst and Svetlana Mojsov, the scientists most closely linked to unravelling GLP-1’s biology. CAR-T cancer therapy pioneer Carl June is also in the predictions.

The Nobel committee is famously unpredictable, and favourites are often passed over. But a win would recognise research that has already changed millions of lives.

Whatever Stockholm decides today, the hormone that started as a curiosity of digestion has become one of medicine’s biggest stories.
