Deaths due to advanced liver scarring (liver cirrhosis) continue to increase, and liver disease is now the 3rd leading cause of premature death in the United Kingdom. The majority of liver disease is lifestyle related (alcohol, obesity and associated type 2 diabetes, injecting drug use) and therefore reversible if caught at a precirrhosis stage. However, current liver function blood tests are poor inadequate, and subsequently a large burden of liver disease is currently missed.
