Bettys Diagnose: The Enduring Pulse of Germany’s Beloved Hospital Drama
BERLIN, 22 January 2026 – For over a decade, the fictional corridors of Aachen’s Karlsklinik have been a Friday evening fixture in German living rooms. “Bettys Diagnose”, ZDF’s enduring hospital series, continues to blend medical emergencies with heartfelt personal drama, now in its twelfth season. The show’s unique legacy is defined by its revolving lead role, with three different actresses having embodied the resilient nurse “Betty” since its 2015 premiere.
From Betty Dewald to Betty Hertz: A Series in Evolution
Launched on 9 January 2015, “Bettys Diagnose” initially followed the competent and headstrong nurse Bettina “Betty” Dewald, played by Bettina Lamprecht. Her clashes with Dr. Marco Behring (Maximilian Grill) and advocacy for patients against hospital bureaucracy set the early tone. In a notable narrative manoeuvre, Lamprecht departed after Season 3. The series seamlessly introduced a new lead character, Betty Weiss, portrayed by Annina Hellenthal from Season 4 onwards, who took over as head nurse.
The latest evolution began in Season 10, with Henrike Hahn stepping into the role as Elisabeth “Betty” Hertz, the current head of the nursing service. This phased transition allowed the series to refresh its central dynamic while maintaining continuity for its loyal audience. The core premise remains: each medical case is a “matter of the heart” for Betty and her team, tackled with empathy, skill, and a dose of humour.
