Diabetes has a leading role in the current global epidemic of non-communicable diseases. But it has a rather ambiguous relationship with the ‘seventh art’. On the one hand, diabetes has made a number of high-profile appearances in blockbuster movies – which has helped to raise its profile among the general public. On the other, it remains underrepresented – only around a dozen films have dealt with the condition in the past 25 years – and is often distorted by the time it reaches the screen. Miguel Abad Vila reviews the portrayal of diabetes by various filmmakers and discusses the film industry’s duty to present diabetes accurately and responsibly.
