Witness History – GLP-1: A breakthrough for diabetes and obesity

Available for over a year

In the 1980s, scientists made a discovery that would eventually lead to the development of drugs now used worldwide to treat diabetes and to help people manage obesity through weight loss injections.

One of the key scientists behind this breakthrough was Svetlana Mojsov. She discovered that a hormone called GLP-1 (glucagon-like peptide-1) plays an important role in how our bodies respond to food.

Svetlana’s work laid the foundation for a drug company to develop treatments based on GLP-1 — first for type 2 diabetes, and later for weight loss. She tells Gill Kearsley her story.
