The Liver Disease 30% of Us Have and Never Feel | Prof Aleksander Krag

Professor Aleksander Krag explains that while a third of adults have fatty liver, the fat itself is harmless—it’s scarring (fibrosis) that predicts liver disease. He breaks down simple, non-invasive tests like FIB-4 and FibroScan that catch fibrosis early and reveals how blood-based alcohol biomarkers expose hidden drinking. The conversation also covers liver damage reversibility, emerging drugs like semaglutide, and the policy changes Krag argues would do more than any clinic.
